The puzzles

Every puzzle is its own game with its own rules and its own look. Each page explains the rules in about a minute, and then you're playing.

Puzzles by kind

What you get in every game

Exactly one solution

Before a board goes into a game, a solver checks that it has one answer and only one.

A daily puzzle

One new board a day, the same for everyone. Mondays are gentle. Sundays are not.

Hints that explain

Stuck? A hint points at the next step and tells you why it works, so you pick up the trick instead of just the answer.
