Penguins .io is an interesting free multiplayer IO game.
Your task is to control one of the penguins on a slippery ice platform and try to run and push other players out of it. Just click and drag on the screen to move and release to jump. Remember that you will slip after jumping, so avoid jumping too close to the edge or you might be the one falling down. Wait until your jumping power reloads and try again.
Let's play the game.
