Fill the grid.
Beat the clock.
Plotwork is the fun, snackable take on Shikaku, the Japanese rectangles puzzle. Every number is the size of its box - draw them all, with no gaps and no overlaps, and the grid is yours. A new daily puzzle every day, free.
It's easy - just fill the grid
Every number is a box
A 6 means a box of six squares - two by three, three by two, or a straight line of six.
Drag to draw it
Press on one corner and drag to the opposite one. The box counts its squares as you go.
Fill every square
One number in every box, no gaps and no overlaps. Get it right and the whole grid lights up.
