What happens in play
You begin as a fly in an open arena. The goal is to eat so that your creature evolves into something stronger, and to keep going until you are the strongest creature in the arena. Eating moves you up; being caught by a predator ends the run.
Survival has a second side: you also have to drink water to stay alive, so the arena is a mix of food stops and water stops. Larger animals are a threat to a small one, so a lot of the game is deciding when to hide and when to move out. Poki lists mouse and arrow-key control, and the game runs on computer, phone and tablet.
“Drink water before you chase food; the game treats water as a survival need, not an extra.”
What each key does

Tips for the first runs
Drink water before you chase food; the game treats water as a survival need, not an extra.
While you are still a fly, stay away from larger creatures and treat hiding as a normal move.
Pick one control method, mouse or arrow keys, and stay with it for the first few runs so your steering becomes predictable.
Leave an arena area when a predator is close instead of waiting to see if it notices you.

The kind of player it fits
Players who enjoy io-style arenas and a slow climb from the smallest creature to the biggest.
Where it can frustrate
- Poki does not state an age suitability for it.
- Poki is an ad-supported platform, so expect advertising around the game on poki.com.
- Because other creatures can end a run quickly early on, the first minutes can feel harsh.
