We've been reading Christmas books with our son this season and one was a Jolly Postman book with a board game. The game needs a counter per player and a die.
It's very simple - roll the dice and move the number. Some spaces move you forward, some backwards, some miss a turn etc.

I know about the probabilities of rolling 1-6 on the die, and the squares you land on are chance - however we've played this little game over 10 times and every single time - whoever has the yellow counter wins. It doesn't matter if I use the yellow counter, or if my son uses the yellow counter - they will always win (so far).
Should the maths determine that technically we should win 50/50? Or could there be some other reasonable explanation, and of we played more then we should see the lock even out?
