Party Animals Cats Evolution

Merging with an idle economy attached. Identical kittens combine into the next species up, and the ladder runs to twenty-one distinct forms — which is long enough that the top of it is a genuine target rather than an afternoon.

The animals generate coins on their own, so the board earns while you are deciding. Coins buy either more starter animals or boosters that speed the whole thing up, and choosing between those two is the only real strategic question the game asks.

It is built to be left running and returned to, which is the honest description of the idle genre when it works.

1. Click two identical animals to merge them.
2. Let the board generate coins while you play.
3. Buy new starter animals or boosters with the coins.
4. Work up the ladder toward the twenty-first species.
