Puzzles made with care, for a calm daily habit

How the puzzles are made

• Every puzzle comes from our own puzzle engines, written for Gridarium. Nothing is copied from another site or book.
• Each one is checked before you see it: it has exactly one solution, and it can be finished by reasoning alone. You never have to guess.
• Levels mean something. A puzzle is graded by the techniques a person needs to finish it, step by step, the way you would solve it on paper, not by how many squares are empty.
• The daily puzzle is the same for everyone on the same day, and it changes at your own midnight.

Calm by design

• The timer can be hidden, and speed never earns points: effort does.
• Your streak forgives a missed day, because life happens.
• Large, clear type, strong contrast, big buttons and full keyboard and screen reader support are features, not extras.
