Open. Capture. Conquer.

Everything about Catch a Crate in one place: every crate, brainrot, boss, item, mount and event, with the real odds straight from the game.

How to play

Crates fall from the sky. You open them to get brainrots. Brainrots make money at your base. More money means better crates. That is the whole loop!

Two kinds of money

Cash ($)

Your brainrots make cash every second. It piles up at your base: walk onto your base and press CLAIM to collect it.

Spend it on: crates, display cases, generator upgrades and rebirths.

Crescents

The rare money. You get it from daily rewards, boss wins, events, the Bestiary, Blood monsters and just playing (5 every 15 minutes).

Spend it in the Crescent Market and at the Blood Altar.

Good first goals

  • Fill your 3 free display cases, then buy case 4 for just $750.
  • Spin your Random Crate Generator at your base. Spins are free and refill every 5 minutes, even while you are away.
  • Claim your daily reward every day. Day 30 gives 15,000 Crescents!

  • Fill in the Bestiary: the first time you get any brainrot or crate you earn Crescents.

Crates

Crates rain onto the crate fields: up to 8 every 15 seconds, and never more than 60 at once. Rarer crates cost more, need more clicks and hold better brainrots. Crates nobody buys disappear after a few minutes. Tap a crate to see what's inside.

How opening works

1. Pay

Your first click buys the crate. Its price is on its tag. Once you pay, it's yours: nobody else can take it.

2. Click it open

Keep clicking. A Common takes 2 clicks, an Omnipotent takes 50.

3. Watch out, it's alive!

Halfway through, a crate (Common to Exotic) has a 50% chance to grow legs and run off! Chase it down and keep clicking.

4. Stop the meter

A meter swings up and down. Stop it in the GOLD for the best brainrot, ORANGE for the middle one. RED gives the basic one.

Crate odds change the luck to see how it helps

x1

Luck Card rituals and Server Luck boosts make every crate except Common more likely. Their bonuses add up: a 2x card plus a 3x boost is 4x.

Try it: make it rain

Drop 8 crates with the real odds (and the luck you picked above).

Try it: open a crate

Practise the real meter. It swings just as fast as in the game: one full swing every 0.8 seconds.

The super rare ones

Good to know

  • Base full? If all your display cases are full, a new brainrot only stays if it's better than your weakest one. You get a warning before you buy.
  • Lightning in a storm can blow up crates that nobody has bought yet.
  • Opening a Mythical or better crate is announced to the whole server.
  • The Rubble Buddy makes your crates need 25% fewer clicks. A Siege Ram finishes all the clicks at once (and stops a runaway crate dead).
  • A Blessed Key turns a crate you're opening into the next rarity up.

Brainrots

Brainrots are what you collect. Every crate holds 3 of them: a basic one, a better one and the best one. Put them in your display cases and they make cash every second.

Fusion: 3 become 1

Go to the Arcane Altar with 3 copies of the same brainrot equipped, and fuse them into the next brainrot on the ladder. The top one of a rarity fuses into the first one of the next rarity!

Boosted brainrots fuse too (3 Boosted make a Boosted next one). Blood monsters can't be fused.

Boosted brainrots have a gold outline and make 2.5x cash. You get them from the Boosted crates that bosses give you.

Tip: 3 of the top Omnipotent brainrot can't be fused. It's the end of the ladder.

The fusion ladder tap any brainrot

Blood monsters

Bought with Crescents at the Blood Altar during a Blood Moon. They make cash and Crescents from your display case, and get stronger with every Blood Moon (up to 10).

Your base

Your base holds your display cases, a trash can and your own Random Crate Generator. Press BASE any time to go home.

Display cases

Each case shows one brainrot, and each one makes cash. You start with 3 free cases and can buy up to 10.

Cash and Crescents pile up at your base. Stand on your base and press CLAIM. Nothing is ever lost: if you leave, it's banked for you.

Don't want a brainrot? Throw it in the trash can at your base.

Random Crate Generator

A slot machine at the back of your base. Spins are free: you start with 10 and get 1 back every 5 minutes, even while you're offline. Pull the lever and it lands a crate, which goes into the Crates tab of your inventory. Open it there, or fight its boss!

It uses the same odds as the sky. Upgrade it with cash (and Crescents at the higher levels):

Rebirth

When you're rich enough, rebirth for +15% cash forever and +15 max health. To rebirth you need the cash, and every display case you've unlocked must hold a brainrot of that rebirth's rarity or better (not a Blood monster).

You lose: all your cash, all your brainrots, your Luck Cards and your Crowbar.

You keep: your display cases, Crescents, items, cosmetics, mounts and every weapon from Items crates.

Rebirth 2 gives the Coin Roller mount, rebirth 4 the Pogo Stick. You can rebirth 12 times.

Health

Everyone starts with 100 health. Each rebirth adds 15. Wearing cosmetics adds more (you can wear 2 at once): from +10 for Common up to +120 for Celestial. The most anyone can have is 500. Mounts don't add health.

Capture & bosses

With a Magnet you can capture a crate instead of opening it. Captured crates wait in your inventory. Open them later, or challenge the crate's boss for big rewards.

The Magnet duel

Buy a Magnet in the Crescent Market (10 for 3 uses). Hold it and click a crate nobody has bought. A tug-of-war starts: win quick minigames to push the bar up. Full bar = captured. Empty bar = it breaks free.

Capturing costs 3x the crate's price.

Minigames: Overcharge (mash), Channel (hold), Strike (hit the zone), Surge (press the key), Counter, Deflect, Lock On and Redirect.

Boss fights

Open your inventory, go to Crates, pick a captured crate and press CHALLENGE. Go alone or invite up to 5 friends. Everyone needs a weapon, and you can pack up to 3 items.

How to win: dodge the warnings on the ground. After an attack, one of its armour plates swings open. Run round and hit it! Break 2 plates and the boss gets dizzy: now every click and hit does big damage.

Knocked out? You watch your team. If they win, you get the rewards too.

Every win pays: Crescents (), a Boosted crate of that rarity (its brainrot makes 2.5x cash) and an Items crate of that rarity. Everyone in the party gets all of it. More players = more boss health (+65% per extra player).

The crate bosses

Weapons

You need a weapon to fight a boss. The Crowbar is sold in the Crescent Market. Every other weapon comes from Items crates, has a special move (F) and is kept when you rebirth.

WeaponRarityStyleReachSpecial moveRecharge

Items

Items come from Items crates (boss rewards), the Crescent Market, daily rewards and the shop. Most help in boss fights. Some help you anywhere.

What's in each Items crate

You get one from every boss win (and the Blood Crate from the Blood Altar). Weapons, cosmetics and mounts are one of each: once you own one, it can't drop again.

The Crescent Market

Always for sale:

Luck Cards: 3 random cards are in stock, changing every 10 minutes. They cost cash and Crescents.

CardLuckLastsPriceIn stock

The Luck Card ritual

Two or more players hold the same kind of Luck Card and stand together for 10 seconds. The cards smash together and the luck of every card is added up, boosting the crates falling for the whole server. The cards are used up.

Mounts & cosmetics

Mounts are rides with a special power (press Q to hop on). Cosmetics are things you wear: each one has a perk and gives you extra health. You can wear 2 at once.

Events

Big moments that change the whole server. Only one big event can happen at a time.

The Frozen Citadel horde

During the Great Freeze you hold the citadel for 20 waves. Elite waves (5, 10, 15 and 20) are tougher and pay double, and wave 20 wakes the Glacier Colossus. Waves 5, 10, 15 and 20 also give an Items crate. Monsters you hit can drop Items crates just for you.

The monsters (tap one to see what it can drop):

Knocked out? You're frozen solid until the wave is cleared, then you thaw at full health. If everyone is frozen at once, the citadel falls. Hold all 20 waves to win the Glacier Mammoth mount.
