TARDIS hopscotch

TARDIS hopscotch was a game designed by the Celestial Toymaker for use in his world, the Celestial Toyroom. It was so called because it led to the First Doctor's TARDIS. TARDIS hopscotch was played by rolling a die, then using its face-value to determine the number of spaces moved. The floor between spaces was heavily electrified.

Dodo Chaplet and Steven Taylor played TARDIS hopscotch as the final game of their trials. In it they competed against Cyril, who frequently resorted to underhanded methods. Cyril was killed when, in a rush of glee, he slipped on his own trap and fell into the electric field. Dodo and Steven continued playing until they won and were reunited with the TARDIS.
