Trilogic Game

The Trilogic game was a game played by the Doctor and the Celestial Toymaker. The rules were as follows: There was a tower made up of 10 plates, each one smaller than the one it was on top of, forming a pyramid-like shape. There were three spaces, A, B, and C where the pieces can be moved. The goal was to move the entire stack from A to C. However, only one piece may be moved at a time, and a piece cannot be placed on top of one smaller than it. The Celestial Toymaker gave the Doctor only 1023 moves to finish the game, or he would be trapped in the Toymaker's world forever.(DW: The Celestial Toymaker)
