Fivefold Quilt

Keyboard & design notes

Tab to a cell; arrow keys move focus; Enter or Space activates it. Number keys activate the numbered controls. R restarts. Cells are numbered 1–25 in reading order.

Five distinct pentominoes: I, L, P, V and T. No loss; invalid placements do not spend pieces. Undo recovers the prior placement.
