FAQ

Rainbow questions

What do you actually do in Build An Ant Empire?

Roll an offer at the Ant Queen, buy the ant with Cash, place it in a nest slot, collect the food boxes it produces, sell those boxes for Cash, then spend Cash on egg luck, egg rolls, food income, slots, and later mutations.

How do codes work?

Finish the short tutorial, click the gear icon at the top-right, open Settings, paste one code, and press Redeem. wnixh2 is listed for 100 Star Coins. 9hcb2s is a 15-minute Cash boost that an earlier page said would expire on October 9, 2026, even though later lists still showed it as active.

What should a new colony buy first?

Buy Egg Luck and Egg Rolls first while you keep enough Cash to purchase a strong offer. Then raise food income and add slots when you have ants worth placing. Buy Ant Speed when trips, not ant quality, are the bottleneck.

Which mutation is the strongest?

Starlight is the strongest listed mutation at 5x EFF and a cash price of $5.1Qi. Petal is 3x at $500T. Put those on ants you will keep. Leaf at 1.35x and $1M is only a first mutate for a keeper, not for a Common you plan to replace.

Do pets replace worker ants?

No. Pets come from Pet Eggs bought with Dungeon Pet Coins. They are companions with their own bonuses. Worker ants still produce food, and mount training is a third system that removes the ant you submit.

Are there gamepasses?

An October 5, 2026 catalog of the Roblox shop says there are no gamepasses and that the listed products are one-time buys. Cash prices in the center item shop are a separate list from those Robux prices.
