Rules

  • All 3 must be the same pet. Same rarity is not enough.
  • The 3 can have different weights and mutations.
  • There is no cooldown.
  • The machine says better pets give more luck. No site has the real odds.

Keep These Out

  • Mutated pets. A mutation does not carry over. Even 3 pets with the same mutation can lose it.
  • Your best copy of each pet. Weight does not add up. One player fused 3 Scorpions of 457, 256, and 247 kg and got 86 kg.
  • Pets that earn a lot. The new pet rarely beats all 3 together.

Common Questions

Do mutations carry over when fusing?

No. A mutated pet can come out with no mutation, even when all 3 pets have the same one.

Why did my fused pet get smaller?

Size is rolled again. It does not add up the 3 pets.

Is there a cooldown?

No. Fuse any time you have 3 pets and the cash.
