Establish Your Paper Kingdom

Use your mouse to direct your square. You must determine your area. Your square will leave traces as it is moving. Mark your territory by returning your starting point. A pro tip from us: move cautiously without going too far in the beginning, as you will be open to attacks from other squares.

Guard Your Tail

When a square touches your tail, you will fail the game. So, give weight to not expose your tail too long outside your land. But, likewise, when you catch an enemy whose tail is out, use your chance to eliminate him from the playing field.

Do Not Swallow Your Tail

As other players can catch your tail, you may also accidentally swallow your own! Biting your tail will cause you to lose the game. Therefore, we recommend that you do not let this happen. Do not swallow your tail!
