A game played with coins has the following rules.
1. Coins are set up in a triangle.
2. Coins are moved until the triangle is upside down.
3. The number of moves is recorded.
For example, if a two-layer triangle is used, then only one move is required to flip the triangle.
A three-layer triangle would only require two moves.
