Why it matters
Boosts are the difference between a grind and a sprint. A 30-minute 2x Money window with a full PIT lineup out-earns an hour of normal play — and codes make the best boosts free.
Boost Types
There are three ways boosts reach your coop:
- Timed code boosts. Free 2x Money and 2x Corn windows from redeemable codes — typically 30 minutes.
- Permanent gamepass boosts. Double Money, Double Corn and Fusion Master multiply every session, forever.
- Boost chickens. Rare chickens like the Corn boost chicken hatch from the Scratch Egg and grant a boost while active in your roster.
Free Boosts — Active Codes
Codes are the cheapest boosts in the game. The current active set includes:
| Code | Boost |
|---|---|
| LETMECOOK | 50 Cash + 1 Thunder Egg + 2x Money Boost (30 min) |
| EGGSCELLENT | 50 Cash + 1 Thunder Egg + 2x Corn Boost (30 min) |
| SERGIOVERSE | 50 Cash + 1 Scratch Egg + 2x Corn Boost (30 min) |
Codes expire, so always check the live codes page before planning a boost session — and redeem before spending earned currency.
Permanent Boosts — Gamepasses
Gamepasses are the only permanent boosts. Prices and picks from our gamepass guide:
- Double Money (299 Robux) — doubles all Cash income. The single fastest economy booster and the best first buy.
- Double Corn (299 Robux) — doubles Corn production for laying and feeding. Strong if you rely on egg income.
- Fusion Master (1,199 Robux) — boosts fusion efficiency. Worth it once you start building a mutated roster.
Stacking Rules
- Codes stack with every gamepass. A 2x Money code plus Double Money multiplies further — never sit on a code boost during a paid-double account.
- Corn and Money boosts can run together. A 2x Corn window feeds the laying chain while 2x Money runs the PIT.
- Timed boosts tick down in real time. Log out with a live window and it may expire before you return — plan the offline session around it.
When to Use a Boost
- 2x Money: start a PIT-heavy session. Line up your strongest fighters, then pop the boost — background Cash plus fighting income double for the full window.
- 2x Corn: before laying or fusion. Feed the laying chain or stock Corn for fusion before opening eggs.
- Events beat normal grinding. During Chicken Boss or boost events, spend boost windows on event eggs and event income first.
- Stack with rebirth timing. Post-rebirth, a boost window accelerates the race back past your old tower floor. See when to reset.
Common Boost Mistakes
- Popping 2x Money with an empty PIT. The window multiplies nothing. Prep the lineup first.
- Sitting on a code boost you already redeemed. Use the window before it expires — logging out mid-boost wastes it.
- Buying Double Corn before Double Money. Money pays for everything after; Corn is the complement, not the foundation.
- Ignoring boost chickens. A Corn boost chicken from the Scratch Egg is a free permanent-ish boost sitting in your pool — don't sell it as fodder. See the sell guide.
Boosts FAQ
How long do code boosts last? The current active set grants 30-minute 2x windows alongside eggs and Cash.
Can I use more than one code at once? Redeem the full live set — different codes grant different boost types that run together, and each stacks with gamepasses.
Do boosts work offline? Log back in before the window ends and farm the stockpile during the bonus — the offline income guide covers the full setup.
