Crease is a free daily puzzle game about folding a strip of numbers. It has no accounts, no sign-up and no tracking of what you do in the game.
Each day's puzzle is generated from the date by a program. The program picks a random strip, folds it a few times to make the target, then runs a solver to confirm the puzzle can be solved in exactly that many folds and has very few solutions. Every player gets the same puzzle on the same date.
