Math Game – NIM 37 – Addition Strategy Game
NIM 37 is a two-player mathematical strategy game. In this version, a counter is moved around the board and a running total is kept. The player who takes the running total to 37 loses the game. There is a lot of mathematical thinking in this game. Heaps to investigate!
What you Need:
2 Players
1 Counter
How to Play:
1. The person with the highest number made from the last 3 digits of their phone number goes first.
2. Player One places a counter on any number on the game board. This is the score for the move.
3. Player Two then slides the counter to a different number along the blue lines. This number is added to the first to give the running total.
4. Play continues in this fashion until one of the players is forced to make the total 37.
How to Win:

The person who takes the running total to 37 loses the game.

OR 

The person who forces their opponent to go over 37 wins the game.

Variations:

Investigations:

– Does aiming to take your total to an odd number help you win more games?
– Does aiming to take your total to an even number help you win more games?
