This is a set of stacking tokens to play the mathematical game of Nim. If you know the winning strategy, you will never lose unless the other player also knows the winning strategy.
This is a first draft and I intend to create stacking version that is travel friendly, or pocketable, so I can challenge people I meet and… win.
I find this a great game to get students interested in learning exponential functions by telling them to search for exponential patterns.
