Constitutional Draughts was invented by Mike Zapawa in 2020 to reduce the number of draws compared to its parent game.

The rules are the same as those of International Draughts with the following difference:

  • If a king makes a non-capturing move it may not move over a square where it would be captured by a king if it would stop there. However, it may move onto such a square to sacrifice itself (or to 'stick' there if the opponent must make a bigger capture elsewhere).
