Sudoku Soap

Scratch to play

(+6, -3)

Layers and layers of Sudoku games in a bar of soap.

Wash up a bit to expose the game, and then play by scratching the numbers onto the bar.

Keep washing to get to the next game.

An excuse to get clean, I guess. +

I don't think it would unlayer evenly, but maybe the tiles on your bathroom wall could be made into a sudoku grid instead?

I think you could get it to unlayer evenly... maybe alternate dense and softer layers when making it.

The bathroom tiles... hmmm... that's a thought.
