Start Splitting and Selling

  1. Split your cells. Use SPLIT at the bottom of the screen to increase your population. Wait for the cooldown, then split again. Splitting can also produce mutations.

  2. Sell for cash. Use SELL to turn your batch into money for upgrades. You can sell before reaching capacity.

  3. Improve the next batch. Buy upgrades from the right-side panel, then continue splitting and selling.

  4. Try a challenge. Once CHALLENGE becomes available, enter to work toward cash targets with limited SELL attempts.

Upgrades and Cash

When to sell depends on your current goal:

  • Normal production: Check how much capacity remains; a full population has no room to grow.
  • Timed sale bonuses: Sell before the relevant bonus expires.
  • Challenges: Check the target and remaining TRIES before using another sale.

Income also depends on the cells in your batch, mutations, cards, and active bonuses. A larger population alone does not determine the payout.

Mutations and Fusion

Find and identify mutations

Splitting can produce mutated cells. Open MUTATIONS to check your collection and YOUR BEST BALL to inspect its composition. Wings and halos are equipped accessories, not defining mutation features. For more discovery opportunities, compare mutation boosts and when to use them.

Read a fused ball

Hover over a ball to see its VALUE, TRAITS, and overall PAYS multiplier. One ball can contain several value mutations and traits: the five-mutation Penta-Mutant Vampire example combines Toxic, Gold, and Stone with Vampire and Coin Ball, and pays ×14.

Use the displayed PAYS value for the whole ball rather than multiplying its individual VALUE entries. Other fusion combinations show how these categories coexist.

Handle Rotten warnings

A Rotten warning shows a $0 payout. Click the affected ball before splitting and look for CURED! feedback.

Challenges and Bosses

Open CHALLENGE when its entry becomes available. Each set has three goals, with a Boss restriction on the third. Every SELL spends one try and adds credited earnings toward the current target. Failing a goal does not make you lose anything.

  • One Try Fewer: Prepare larger batches because you have one less sale attempt.
  • Splits Take Twice as Long: Allow the full, longer cooldown before splitting again.
  • Only Half of Your Balls Pay: Judge each sale by the actual progress added to the goal bar.

Reaching a goal brings up CASH OUT. Its amount is separate from the goal target; rewards can include cash, Tokens, or cards. Beating the Boss completes the set and opens the Card Shop.

Mitosis Challenges and Bosses: Goals, Tries and Rewards

Calculate the remaining challenge target and average credited cash needed per remaining SELL attempt.

Remaining cash = max(target cash − credited cash, 0). Average cash needed per remaining sale = remaining cash ÷ remaining SELL attempts.

  • Each SELL consumes one attempt and adds its credited earnings to the current goal.
  • Enter the remaining attempts shown on the goal bar, including any Boss restriction.
  • Credited cash is the amount counted toward the goal after applicable restrictions.
  • The result is a target budget, not a prediction of the next sale or CASH OUT reward.

Cards and Loadouts

  • Get cards: Earn them through challenge rewards or buy offers in the Card Shop with Tokens.
  • Arrange cards: Drag them in My Cards. Effects activate from left to right.
  • Sell cards: Open a card's details to see its SELL option and Token value.

No Wait is a cooldown-related card named as a route to the Minimum Cooldown achievement. For shop rerolls, slot options, and management controls, use the card management guide.

Tokens and the Skill Tree

Earn and spend Tokens

  • Rebirth and challenges: Award Tokens as part of progression.
  • Daily Spin: Can award Tokens through results such as Token Stash.
  • Card sales: Card details show a Token SELL value.
  • Meteor Shower: Its event card can display a Token reward indicator.

Spend Tokens on skills, Card Shop purchases, and shop rerolls. The TOKENS panel describes a +2% money bonus per token; read its displayed bonus when assessing your progress. The Token guide covers sources and spending choices.

Unlock automatic splitting

Buy the central Auto-Split skill for 5 Tokens, then enable AUTO beside SPLIT. You can buy it before your first rebirth and without purchasing another skill first.

Buying Auto-Split reveals Quick Start, Tokens I, Value I, and Slot 4. Their costs and the starting branch are covered in the Auto-Split and skills guide.

Rebirth

Open the circular-arrow Rebirth button on the left to preview your reward in TOKENS. Check READY, the expected Token award, and the before-and-after money bonus.

  • Reset: Cash and the three basic upgrades—Ball Value, Split Speed, and Capacity—return to zero. You will need to rebuild production and buy cash upgrades again.
  • Keep: Your level and XP progress carry over.

Your first rebirth also unlocks Wheel Spin.

  • Millionaire: Earn $1,000,000 in total.

QUICK ANSWERS

Good to know

Do I need to rebirth before unlocking Auto-Split?

No. Buy the central Auto-Split skill for 5 Tokens, then enable AUTO beside SPLIT. No earlier skill purchase is required. See the Auto-Split guide for the starting branch.

Does rebirth reset my level and XP?

No. Your level and XP carry over, while cash and the Ball Value, Split Speed, and Capacity upgrade levels reset. Check your reward preview before rebirthing.

Do Lab Goggles give the level 5 sale bonus?

No. Lab Goggles and the +5% cash-on-every-sale bonus are separate level 5 rewards. Claim the cash bonus through Level Rewards; it is not a goggles equipment effect.

How do I leave the splitting screen?

Click the Exit door in the lower-left corner and wait for the teleport transition to return to the 3D world. The beginner guide shows the control.
