Primaries No. 1

1. Fill the canvas with rectangles.
2. Every rectangle must be a different shape. A 2×3 and a 3×2 count as the same.
3. Keep them close in size. Your score is the gap: the biggest rectangle’s area minus the smallest’s. Lower is better.

Any finished canvas can be framed and signed on the day’s wall. Improve it as often as you like. The smallest gap possible is perfect. A new canvas every day.

Some canvases have black squares (leave them empty) or a fixed rectangle, marked with a small square in its corner.

Drag to draw a rectangle. Tap one to remove it.
