Maths Inquiry - Fair or Unfair?

We have been experimenting with fair and unfair games and are currently making our own unfair maths games.

 When you throw the counter you get more points if it goes in the tube but the tube is closer to one side and the other side has lots of piranhas. If you land on a piranha you miss your turn.

 We are making our game board.
