Cross the Stream How to Play: • This is a game for two players. • One player (Odd Todd) must try to roll as many odd numbers as they can and the other player (Even Steven) must roll as many even numbers as they can. • Decide who will be Odd Todd or Even Steven. • Take it in turns to roll a dice. If you roll a number you need, then you can colour in a stepping stone. For example, Odd Todd can only colour in a stone when they roll an odd number. • If you are the first to colour in all of your stepping stones, you win the game!
