Try 2 practice puzzles. Nothing is timed, and the board helps you along.
Then solve as many puzzles as you can in 120 seconds. They get harder as you solve them.

Use the arrow keys to move between cells, the number keys to fill one, and Backspace to clear it. The number buttons work too.

How to play

Region Grid practices working out what must be true. Fill each empty square with a number so that every row, every column and every lettered shape holds each number once. Each puzzle has one answer that you can reach by reasoning. A number that does not fit is marked and counted, and not placed. Use the arrow keys to move between squares, the number keys to fill one, and Backspace to clear it, or tap a square and then a number.
