StartTwo players (or one player and the computer) take it in turns to move the lifesaver ring on to a number. This number is added to the running total for this game. The object of the game is to reach a total of 23. If a player makes the running total greater than 23 they have lost.
This game also works well with students playing in pairs at desks around the classroom. After each game the players move to a new desk, winners moving clockwise around the room and losers moving anticlockwise.
The game will need to be played a number of times by students before they start to see that there are some strategies that can be employed.
Note that each player has to move the lifesaver ring to a new number when it is their turn, they cannot stay on the number the lifesaver ring is on.
For the 1 player game above it is always possible to beat the computer as the player always has first move.

"Turning The Dice Game: This is played with a single die. The first player calls any number, from 1 to 6, and the second player throws the die. Then they take it in turns to roll over the die in any direction they choose, but never giving it more than a quarter turn. The score increases as they proceed, and the player wins who manages to score 25 or force their opponent to score beyond 25.
I will give an example game. A calls 6, and B happens to throw a 3, making the score 9. Now A decides to turn up 1, scoring 10; B turns up 3, scoring 13; A turns up 6, scoring 19; B turns up 3, scoring 22; A turns up 1, scoring 23; and B turns up 2, scoring 25 and wins.
What call should A make in order to have the best chance of winning?
Remember that the numbers on opposite sides of a correct die always sum to 7."
