About this game

The log floats in a pond and you see it from its end, so it is a circle. Red stands on the left of the top and Green on the right. Each player has two buttons in their own bottom corner of the screen.

Hold a button to run that way. The log rolls the other way under your feet and carries the other player with it. Stand too far down the side and your weight turns the log further, so it gets harder to climb back.

The players can't get past each other. Run into someone who is standing still and they are knocked back. When both players run at each other, both bounce back, and the slower one is thrown further.

There is one trick. Let go of your button just before the other player hits you and you dig your boots in for a moment. They bounce off and stumble backwards, and their buttons do nothing until they get their feet back. Dig in too early and it wears off before they arrive.

A player who goes too far down the side slips and slides into the water, and the other player gets the point. First to 3 wins. The log is thinner in each round, so it turns faster.

If both players hang back, waves start to come in after 8 seconds. Each wave turns the log harder than the one before.

On your own, you play Red against the computer. On easy it can be beaten by running straight at it. On medium and hard it digs in when it sees you coming.
