A real run of the game, recorded with captions and no sound.

Fill every row and every column with the digits 1 to 9, each once.
The thick borders outline nine irregular regions of nine cells. Each region must also hold 1 to 9 once.
Tap a cell, then a number. Notes lets you pencil in candidates, and conflicts are shown in red.
The regions change with every puzzle, so there is a new shape to learn each day. There is exactly one solution.

Controls: mouse, touch or keyboard. Made by CalcoTools.

Trace each region's shape before you start. A long thin region behaves like a row.
Regions that run through a row take all their cells there, which tells you where a digit cannot go in the rest of the row.
Start where a region meets many filled cells, since its remaining digits are limited.
Notes help most in the narrow parts of a region, where two or three cells share the same few candidates.
