Daily puzzles

One new position for each game, every day. Solve at least one of them to extend your streak; solve all six for a full row of snowflakes.

The weekly rhythm

The week sets the level. Monday and Tuesday bring gentle positions, Wednesday and Thursday sharper ones, and from Friday to Sunday the deep ones. A new set appears at midnight by the clock on your own device.

A streak grows by one for each calendar day with at least one daily position solved, and breaks after a day without. It lives only in this browser; another phone or computer keeps a count of its own.
