What should I spend gems on in Primitive Brothers?

Choose a build and follow it. Companion build is currently recommended. Early on, get all muscles to +13 before unlocking Bow Bro, and prioritize totems and companion enhancements.

How do I redeem Primitive Brothers coupon codes?

Open the menu (top right), tap the gear icon, select the coupon icon, paste codes one by one, then check your mailbox for rewards.

Should I use alchemy on accessories, runes, or totems?

You should only be using Alchemy on totems for efficient progression.

Why should I get muscles to a low level first?

For attack speed, you gain a small percent of speed every time you level a muscle until it maxes. Many guides recommend +13 before unlocking Bow Bro for companion builds.

Quick Guide

Short on time? These are the most important tips:

Use all Coupon Codes to get around 20,120 free gems. Spend these gems wisely on the next steps.
Get all muscles to +13 before you unlock Bow Bro.
Think about buying the Beginner's Pack and the No Ads option. These provide big benefits.
If you are new, avoid buying chests (except for totems) until you understand the game better.
Join a guild right away. Use public chat to find a helpful guild. You can earn 300 guild tokens daily. NOTE: You will also need to complete your daily quests so that you get a spirit egg bonus, this is mandatory in most guilds.
Do Alchemy every day to improve your totems. Try to turn 8 lesser totems into Rabbit Totems daily.
Always complete daily tasks like Guild Buffs, PVP, Boss Island, Alchemy, Club, and Hospital activities.
Upgrade your totems to level 530 as quickly as you can.
Spend market tokens only on Totem Chests for better progress. Totem Chests are very important.
Before leveling any muscle further past +13, read the full guide to understand how builds work.
When possible, always buy in bulk. Every gem counts and you want to always get that discount.
Come back and read the full guide when you have more time for details.

Time until reset:

Getting Started

Starting Tips

Spend Gems Wisely: Use gems to make your character stronger.
Unlock New Content: Play the game to open new things and activities.
Maximize Daily Activities: Do hourly and daily activities to get gems, tokens, and resources. They add up over time.

Gameplay

Use idle mode to collect resources.
Run the game all day and night for best progress.
Use Sleep Mode to save battery while staying online.
When offline, you get 1 kill per minute, up to 10 hours.

F2P and P2W

The game is free to play, but if you’re considering purchases, here’s the recommended priority order:

No Ads Forever: Removes ads, gives daily gems and chests instantly, and makes "Thor's Might" infinite. Highly recommended.
Rookie Package: Gives a permanent auto-clicker and a 2x stat boost for Bro, Turret, and HP regeneration. Very important.
Intermediate Package: Great follow-up to Rookie Package; adds more value to your early progression.
Orc Uncle: A huge boost to Uncle.
- Attacks as soon as the battle begins.
- Always attacks at the maximum damage rate.
- Probability to attack: +25%
- Crit Rate: +40%
Dark Lightning: Upgrades Thor's Might so each hit always does 10% of the boss's HP, for the maximum of 30% HP damage per battle.
Daily 300 Gems: Passive gem income is always valuable for long-term growth.

Other Helpful Purchases

Extra Totem Deck: Makes it easy to switch between farm and push skill builds.
Monthly Dungeon Pass: Grants 2 extra dungeon tickets per day for 30 days, significantly improving your portal material farming.
Double Turret: Provides a large power boost to your turret. Very helpful for turret-based builds.
Monthly Heart Package: Grants 777 hearts immediately and increases daily heart gain from 100 to 200, helping you level your girlfriend faster.
Figure Box Exchange Tickets: Lets you claim figures missed from past events. Can offer strong bonuses but results are RNG-based and may be disappointing.
Bro Level Pass / Stage Pass / Civilization Pass: These are the most cost-effective ways to acquire gems if you plan to spend real money.
Daily Package Items: Discounted daily gem purchases—another effective and efficient gem acquisition method.

Note: It is not recommended to purchase gems from the weekly or monthly gem packages until you have exhausted the above options, as they are less efficient. Buying gems directly from the “Gems” tab is never recommended due to poor value.

Basic Mechanics

Civilization and Caps

When you reach a new civilization, you get stronger and find more Stone and Rice.
Use stones to level up Bro, Turret, Hut, and ~~Juliette~~ to advance civilizations.
Civilization levels limit some parts of the game, so advancing is important.

Farming and Pushing (Outdated)

Farm stages have the best drop rates before resetting. This makes drops better by one stage.
Farm equipment at farm stages to get stronger and move to the next stage.
There are different farm stages for Gear, Accessories, Turret, and Hut parts. Accessories are the most important.
Skip farm stages with active play until stage 2000. After stage 2000, farm and push from farm to farm.
Try to have at least 1.5 times your current farm stage's power to make pushing easier. Less power means slower farming or not reaching the next stage.
If you choose to go the route of a companion build (Highly recommended), farming becomes unnecessary and is actually a waste of time. Instead, you should focus on pushing to your maximum limits at all times.

Important Update: Farming and Pushing (Current Meta)

Farming for equipment, accessories, turrets, and hut parts is currently pointless.
You only need to farm for Rice and Stone now.
The best way to farm these is to push as many stages as possible.
Forget farming specific stages — focus on pushing your limits to maximize resource gain!

Totem Skills

Totem skills make different parts of the game better, like damage and drop rates.
You get 1 skill point for every 2 successful totem upgrades.
Use different skills for farming and pushing.
If you have an extra totem deck, create 2 skill setups for easy swapping.
Totems also deal damage based on bro strength and the amount of total totem points.

Alchemy

Alchemy lets you change equipment or resources into better items.
Use 100 points for free and refresh 3 times daily for 100, 200, and 300 gems.

Wigs and Masks

Wigs and masks give random stat boosts of 1-5%.
Use dice to change stats and boosts randomly.
For farming, focus on Strength (STR). For pushing, use Evasion (EVA) for slow bosses and Defense (DEF) for fast bosses.

Ranking

Ranking is based on the highest stage you reach.
Server-rank: The first number in your name.
Global-rank: The second number in your name.
Global rank changes your name color.

Ranking Color Guide

Ranking 1 ~ 10
Ranking 11 ~ 100
Ranking 101 ~ 300
Ranking 301 ~ 1,000
Ranking 1,001 ~ 3,000
Ranking 3,001 ~ 10,000
Ranking 10,001 ~ 30,000
Ranking 30,001 ~ 100,000
Ranking 100,001 ~ Remaining Users

The Wall of Space

Space starts at stage 10641.
You need to reach space to go past civilization 75.
Bosses get much stronger between stages 10000 and 10650.
You need a balanced build with good power and HP.

The Wall of The Multiverse

The Multiverse starts at stage 26390.
You need to reach the Multiverse to go past civilization 150.
Bosses get much stronger between stages 25001 and 26390.
You need a specialized build with good power and HP.

The Wall of The Multiverse 2

The Multiverse 2 starts at stage 42,140.
You need to reach the Multiverse to go past civilization 225.
Bosses get much stronger between stages 39,500 and 42,140.
To achieve this, a strong companion build and high HP is strongly recommended.

Battle Mechanics

Boss Battles

Defeat the boss in 12 seconds. If you don't, you lose.
~~Juliette adds an energy bar for boss battles. Keep Juliette's level at least 30 levels higher than Bro's to keep Bro attacking.~~
Use totem skill points to make bosses weaker and increase your damage.

Thor's Might

Deals 5-10% of the boss's HP per try. Use it 3 times per battle to reduce 15-30% of the boss's HP.
With Permanent No-Ads, it's very useful in battles.

Uncle

Uncle also reduces a percentage of the boss's HP.
Fully upgraded, Uncle can remove up to 19.2% of the boss's HP. This helps with the "Space push."
New players should upgrade Uncle with gems when the success rate is high. Later, focus on other parts of the game until you have a strong build.

Grandma

Grandma introduces a revival mechanic. Each level costs 10 Rice Cakes, with a maximum of 150 levels.
Each time you buy a level, one stat is upgraded at random. You cannot choose which stat increases.
The 150 levels are split across five stats:
- Revival Chance: 20 levels, up to 75%
- HP After Revival: 10 levels, up to +60%
- Attack Bonus After Revival: 10 levels, up to +60%
- Additional Combat Time After Revival: 10 levels, up to +4 seconds
- All Stats: 100 levels, up to +400%
Undead Grandma is a premium purchase that adds +25% Revival Chance, +40% HP After Revival, +40% Attack Bonus, +2 seconds of combat time, and doubles all stats (×2).
Undead Grandma is a very powerful P2W purchase — it improves every part of the revival system at once.

Stat Amplifiers

Totems

Totems boost different stats. You can get them by completing stages in the Bronificent Tower.
Every 2 upgrades give you 1 skill point.
Totems make you much stronger, and you should aim to get at least 530 total enhancements as a new player.

Rune Monument

Rune Monuments boost different stats.
Change Rune Shards in the Rune Factory. Get Rune Shards by completing stages in the Rune Shard Dungeon.

Glyph

Unlock Glyphs at stage 3001. They boost different stats.
Every completed tier gives a 1% Civilization boost.
Upgrade the highest tier for the best stats. Then, upgrade from low to high.
When possible, skip upgrading glyphs.
When you unlock glyph transcend you can improve the civilization boost. It is expensive.

Spirits

Spirits can cause damage to the enemy.
They increase all of your stats overall.
You always want to equip a spirit based on the secondary skill. This is mostly determined by lv of a spirit. This is the reason why players mostly equip blue or purple spirits in the beginning; they give the best secondary boost.
Each spirit also amplifies a specific secondary skill depending on the type you choose:

Rat: Increases Strength.
Cow: Increases HP.
Tiger: Increases Turret Engineering.
Rabbit: Increases Hut Construction.
Dragon: Increases Bow & Slingshot Companion Stats.
Snake: Increases Spear and Axe Companion Stats.
Horse: Increases Illustrated Handbook Stats.
Sheep: Increases Challenge Stats.
Monkey: Increases Gear Level Stats.
Chicken: Increases Accessory Level Stats.
Dog: Increases Turret Part Stats.
Pig: Increases Hut Material Stats.

Medals & Half Sibling

Bronze Medals are earned for each continent you finish (70 stages per continent).
Gold is required to level up medals and unlock better boosts.
Bronze Medals: 0% boost
Silver Medals: 0.75% boost
Gold Medals: 1.25% boost
Emerald Medals: 2.5% boost
Gold is collected passively by the Half Sibling and can also be purchased with gems or money in the store.
The Half Sibling collects Gold passively for you.
Upgrade Half Siblings using Gold to increase gathering speed, success rate, and the max amount gathered.
Half Sibling's max level is 50.
A level 50 Half Sibling gives 250 Gold Nuggets per day, worth 750 gems.
With the monthly pass, this increases to 500 Gold Nuggets per day, worth 1500 gems.
Efficiency Tip: To be most efficient, get the Half Sibling to level 50 as fast as possible. After that, upgrade all badges to Silver, then Gold, and finally Emerald. This is the fastest way to maximize the boost you get from Medals.

Girlfriends

Provide all stat boosts.
Unlock stages: 501, 1000, 1500, 2500, 4000, 6000, 8500, 11,500, 15,000, 19,000, 23,500, 28,500, 34,000, 40,000, 46,500.
Gain hearts passively daily up to 100 (200 if you purchase the upgrade in the store). Hearts can also be bought with gems / money.
Each level you upgrade a girlfriend grants a 1% boost.
You can modernize them and equip accessories from the Department Store (earned via VIP level).
Each modernization and accessory adds a star; modernization adds 6% boost and each accessory gives an additional 4% boost.
Note: Strategy is to upgrade all girlfriends equally.

This chart shows the colors used in the Girlfriend dating mini-game, which is how you unlock new girlfriends. Use it to unlock the exact girlfriend you want, or to avoid ones you dislike.

Cube of Space-Time

Grants all stat boosts.
Requires different materials to upgrade; required materials may vary at each level.
Lv 1–10: +1% per level
Lv 11–30: +1.5% per level
Lv 31–50: +2% per level
Lv 51–59: +2.5% per level
The early boost looks small, but long term this is one of the most efficient boost mechanics in the game.
From lv60+, the actual power gain increases a bit each level, so it gets efficiently stronger as you keep upgrading. This is not irregular.
Note: The Cube of Space-Time's material cost is based on its worth. Lv1 costs materials worth 500 gems per attempt, increasing by +50 gems per level until Lv67. After that, the cost increases by +100 gems for each attempt.

Slates

Unlock stage: 9001. They can only be used after stage 10,641.
There are 11 slate types across 8 tiers.
Every slate you own contributes to a tier collection bonus that amplifies all slate buffs.
Types:

All Stat — best overall slate.
Hero Stat
Gear Level
Accessory Level
Turret Engineering — 2nd best for turret builds.
Turret Part Level
Hut Construction
Hut Material Level
Illustrated Handbook Stat
Challenge Stats
Companion Stats — 2nd best for companion builds.

Tiers & Buffs: each tier has a base buff and a collection bonus.

Common — 0.5% buff, 0.5% bonus
Uncommon — 1% buff, 1% bonus

Epic — 3% buff, 2% bonus
Legendary — 5% buff, 2.5% bonus
Mythic — 7.5% buff, 3% bonus
Abyssal — 10% buff, 4% bonus
God — 12.5% buff, 5% bonus

Strategy: Unlock and fill all slots with Epic or higher All Stat slates plus your build’s 2nd-best stat (Companion Stats or Turret Engineering). After that, replace the lowest-tier slates — prioritize the 2nd-best stat over All Stat. You can also fill every slot with All Stat only. That is more expensive, but it gives better survivability.

Relics

There are 5 tiers, each holding 12 relics, which all have 100 upgrades to max.
High risk / High reward mechanic.
Successful upgrades will randomly increase one of the relics in the current tier.
Every 12 successful upgrades in a tier will decrease the success chance by 1%.
Upgrade using pickaxes equal to the level you are upgrading.
Strategy: Max relics that complement you build in a tier first before moving to the next tier. The stat increment will increase with each level, becoming huge at the last few levels before max
Level 1 (max): +200% buff
Level 2 (max): +400% buff
Level 3 (max): +600% buff
Level 4 (max): +800% buff
Level 5 (max): +1000% buff
Relic names & buffs:

Advancing Torch — Bro Strength
War Drum — Bro HP <-- always max
Feather of Prophecy — Turret Engineering
Mask of Abyss — Spear/Axe Bro Stats <-- always max
Horn of Awakening — Bow/Slingshot Bro Stats <-- always max
Giant's Statue — Hut Construction <-- always max
Sage's Fan — Illustrated Handbook Stats

Emblems

Provide all stat boosts.
Unlocked through leaderboard progression — you gain access to new emblems as you climb in global rank or push to higher stages.
When you meet a rank requirement, you can craft the emblem using gems. Once crafted, the bonus is permanent and is not lost even if your rank drops.
Warning: If your rank falls below the emblem you are currently crafting, the craft stops and the gems spent are lost.
Tiers by rank:

Common (Rank 10,000–5,500) — +2% per emblem, 300 gems, 15 min
Uncommon (Rank 5,000–600) — +3% per emblem, 500 gems, 30 min
Rare (Rank 500–401) — +2% per emblem, 700 gems, 1 hr
Epic (Rank 400–301) — +3% per emblem, 1,050 gems, 1 hr 30 min
Legendary (Rank 300–201) — +4% per emblem, 1,400 gems, 2 hr
Mythic (Rank 200–101) — +5% per emblem, 1,750 gems, 2 hr 30 min
Abyssal (Rank 100–11) — +6% per emblem, 2,100 gems, 3 hr
God (Rank 10–1) — % varies; price and craft time unknown

Note: From Rare to Abyssal, every 5th emblem gives 3× more all stats, costs 3× more gems, and takes 3× longer to craft.
Strategy: Craft as many emblems as you can, but be careful near rank thresholds — avoid starting a craft if a rank drop would cancel it and waste your gems.

Archmage House

Found in the town. Provides all stat boosts.
Unlock stage: 20,001.
Spend 300 magic powder to imbue magic into your wigs and masks.
Imbuing a wig/mask rolls one of the following tiers:

Common (59.5% chance) — +0.5% all stats, +1 point
Uncommon (15% chance) — +1% all stats, +2 points
Rare (10% chance) — +1.5% all stats, +3 points
Epic (7% chance) — +2% all stats, +4 points
Legendary (4% chance) — +2.5% all stats, +5 points
Mythic (2% chance) — +3% all stats, +6 points
Abysmal (1.5% chance) — +5% all stats, +10 points
God (1% chance) — +10% all stats, +25 points

Note: If you imbue a wig/mask that was already imbued, the old effect is replaced with the new one.
For every 100 points you can level up the Staff, which amplifies Wig and Mask all-stats effects.
Strategy: Watch ads to unlock all Wigs and Masks if you haven’t already. Imbue all wigs/masks once, then replace all Common with Uncommon or higher. After that, replace all Uncommon with Rare or higher. Keep replacing the weakest pieces into higher tiers until everything is God tier. If you are a new player, you can stop spending gems on powder after everything is Uncommon or higher.

Figures

Figures provide various benefits in battle. Here are some key points:

Earn figures by completing holiday events throughout the year.
Equip a figure by navigating to Artifacts and selecting the Figure tab.
Purchase a "Figure Box Exchange Ticket" to unlock a random figure.
Figures are a strategic way to enhance your stats; choose ones that complement your build.

Vehicles & Wings

Your bro rides into battle using Vehicles and his Wings. While these don't provide any direct benefits on their own, both can be upgraded to significantly boost all your stats.

Vehicles are upgraded using Fuel, which can be purchased from the in-game store or earned in the portal.
Wings are upgraded using Feathers, which can be purchased from the in-game store or earned in the portal.
Upgrading either one increases your all stats bonus, which enhances every stat across your character and is considered one of the most valuable boosts.
Try to upgrade all your unlocked vehicles and wings evenly. When upgrades become too expensive, shift focus to others until new options become available.
New vehicles and wings tend to offer a much larger benefit at low levels, so prioritize leveling them as soon as they’re unlocked.
Wings are unlocked through leaderboard progression—you’ll gain access to new sets as you climb in global rank or push to higher stages. Once unlocked, the bonus you receive from wings is permanent and will not be lost even if your rank drops, however you will not be able to upgrade them further.

Builds

Invest gems in a specialized build to be more efficient

~~Bro-build:~~ Very outdated and not recommended. You will likely hit a wall around Stage 25,000. Only kept on this page to show historical options. Requires Lv80 Chicken and Rabbit Totem. P2W REQUIRED.
~~Turret-build:~~ Outdated and underperforms past Stage 30,000. Still usable if you want variety, but expect slower progress. Needs Lv80 Deer and Rabbit Totem. P2W REQUIRED.
Companion-build: Currently the strongest and most recommended build. Extremely powerful without needing an auto-clicker. Does require setup and management but is F2P FRIENDLY.

Essentials

186 is the magic number for enhancements, boosting stats by 12,500%.
Alchemy is critical for changing accessories, runes, and totems to suit your build.
All builds need around 510–550 Totem Points for full skill coverage. Specific skill setups are listed on each build's dedicated page.

Companion Build

Currently the best build. It relies on companion skill triggers to do tremendous damage in boss battles. It is also F2P friendly.

Early Game

Enhance Bow Bro to +186. He will be your main damage dealer.
Get total Totem points to 530. This will cover all essential totem skills, defensive and offensive.

Mid Game

The next mechanics are used to boost your build even further. Keep in mind it can take a while as this will cost a lot of gems.

Enhance Slingshot Bro to +186. He shares a common slot for different boost mechanics.
Slates: Fill all slots with Epic or higher All-Stats and Comp-Stats. Then replace the lowest tiers — prioritize Comp-Stats over All-Stats. All-Stats only is more expensive but gives better survivability.
Relics: Max the important stats of Tier 1 which complements the build. (HP, Comp-stats)
Totems: Get 700 totem points to unlock a new All-Stat slot.
Wings & Vehicle: Get everything to lv40 (first yellow star).
Cube of Spacetime: Keep this civ-maxed. The early bonus looks small, but long term it is one of the most efficient boosts in the game — and from lv60+ each level gets stronger.
Spirits: Aim for maxed blue (lv130) and purple (lv100) grade. It costs a few gems but in the end gives plenty of All-Stats.
Smithy: Get all muscle, turret and hut enhancements to 13 → 25 → 50 or 100.
Rune Monument: Aim for +500% boost to your most important stats. You can choose to use the free resources from the Portal and hourly free ads.

Late Game

Enhance Spear and Axe Bro to +186. They both share a common boost slot for different boost mechanics.
Other mechanics can be improved even further.

Long Term

Totem Alchemy is very important for this build. Rabbit totem for survivability and Wolf totem for companion damage output. Always convert 8 totems a day, costing 600 gems.

Rabbit to lv50 → Wolf to lv50
Rabbit to lv80 → Wolf to lv80
Crow to lv80

Smithy

The Smithy unlocks at stage 1001 and provides powerful stat boosts. Be sure to allocate your Smithy points correctly to maximize effectiveness.

Disclaimer: The Bro Build is very old, not recommended, and generally considered ineffective. It remains on the site purely for historical and reference purposes. For the best experience, use the Companion build. Companion is currently the most popular and refined option.
