Nitro Mutation Steal an Egg: How to Get the x2.75 Income Bonus
Learn what the Nitro Mutation does in Steal an Egg, how its x2.75 income multiplier works, and how to earn Trophies in Nitro Race to buy a Nitro Mutation Consumable.
The Nitro Mutation Steal an Egg bonus gives an egg a x2.75 income multiplier. In the mutation stacking formula, that means Nitro contributes +1.75 above the base x1. It is a valuable event reward for improving the Money / Sec of an egg you plan to keep.
This Nitro Mutation Steal an Egg guide explains the reward, how to find and join Nitro Race, how to earn Trophies, and where to buy the Nitro Mutation Consumable.
Nitro Mutation Steal an Egg Income Benefit
| Mutation | Income Multiplier | Stacking Bonus |
|---|---|---|
| Nitro | x2.75 | +1.75 |
For example, an egg with a base income of $100/s becomes $275/s with Nitro before any separate weight or size multiplier is applied. Nitro stacks by adding its +1.75 bonus to other mutation bonuses; it does not multiply their displayed values directly.
For the complete formula and every currently listed mutation, use the Steal an Egg mutations database or the Mutation Multiplier Steal an Egg guide.

- Go to that biome and enter the event.
- Participate in the race to earn Trophies.
- Open the Racing Event shop and spend Trophies on a Nitro Mutation Consumable.
- Use the consumable on the egg you want to improve to apply the Nitro Mutation.
The event interface and shop show the current Trophy cost and available stock, so check them before spending your rewards.
Nitro Race Tips for Earning Trophies
Nitro Race is the route to the Nitro Mutation Steal an Egg reward. Arrive as soon as the on-screen biome announcement appears, since the entrance location can change with the event. Joining races consistently gives you more opportunities to build Trophies for the Racing Event shop.
First-place finishes also progress the Win Pass, while race participation is the way to earn Trophies for shop rewards. Read Steal an Egg New Update #8: Mounts, Shooting Stars & Nitro Race for the broader event overview.
Which Egg Should Receive Nitro?
Because Nitro is an x2.75 multiplier, it is usually most useful on an egg with high base Money / Sec that you expect to keep. Compare candidates in the Steal an Egg Egg Index, then check the additive stacking calculation before using a limited consumable.
Pet weight or size is separate from mutation stacking, so a higher-weight pet can further increase the final income after the Nitro multiplier is applied.
