How to play

Four discs sit on the left post. Take all of them to the right post, one at a time, never putting a larger disc on a smaller one. Tap a post to pick up the top disc and tap another to drop it (or use the arrows and Space). There is a move limit.

The story behind it

Tynwald Hill, on the Isle of Man, has four stepped levels. The discs and the rules of the game are made up. Read the story in Tynwald: the Isle of Man assembly whose name comes from Norse and which still meets on a hill.
