Stage: 3 and 4 Challenge Level: Challenge Level:2 Challenge Level:2

This is a game for two players. You will need a game board and four counters (or coins). You can print out this copy . If you are drawing it yourself, count the spots carefully.

In the interactive game below, four blue counters are placed on certain red spots on a spiral.
Players take turns to move any counter, moving out towards the snail's tail (the white spot).
A counter can only be moved by sliding it ahead 1, 2 or 3 spots.
Counters cannot jump on or pass each other.
When a counter reaches the tail (the white spot), it slides off and is out of the game.

The winner is the player who slides the last counter off the snail.
