# Snail One Hundred

##### Stage: 1 and 2 Challenge Level:

This game is about counting up to 100.

You will need the board which you can downloadÂ here, an ordinary dice and a pair of matching counters for each player.

How to play the game:
To start put both your counters on "0" - which is the snail's eye!

The first player throws the dice and moves one of their counters that number along the snail's body. Take turns at throwing the dice.

After you get to "9" the first counter goes back to "0" and the second counter goes onto "1 ten".

Go on moving the first counter along the snail's body and moving the second counter to the next "ten" every time you get to the end and go from 9 to 0.

The winner is the first to reach "100".
