Shikaku Unlimited is the same 6x6 rectangle puzzle without the daily wait. Each round generates a fresh set of clues with a guaranteed-unique tiling and the same difficulty band as the daily: solvable by deduction alone, never by guessing. Play as many as you like — unlimited rounds do not count toward your daily streak, so they are the place to drill the counting patterns before tomorrow’s board.
Shikaku is a rectangle puzzle on a 6x6 grid. Seven to nine cells carry a clue; every other cell is blank. The whole grid has to end up divided into rectangles, with exactly one clue inside each rectangle.
A clue says two things about its rectangle. The chip's shape is the shape family — square, wider than tall, or taller than wide — and a chip with a dashed rim names no shape at all. The number is the exact cell count, and every clue shows it. How many clues leave their shape open is the difficulty dial, and it is set by a solver rather than by feel.
You draw a rectangle by dragging across it, by tapping two opposite corners, or from the keyboard — arrow to a corner, Enter to anchor, arrows to extend, Enter to close. The outline reads solid when the rectangle is legal and dashed when it is not, so an illegal shape is never committed and never costs anything.
There is no fail state and no guess counter. Tapping a rectangle you already drew takes it back, and Undo walks the whole board backwards. The only measurement is the clock, the same as Queens and Binary.
Every board served here is run through an exact-cover solver first, and only boards with exactly one possible tiling are published — so a board that looks ambiguous never is.
A clue with a dashed rim is not a free choice. Its rectangle still has to fit between its neighbours, and on a 6x6 board that usually leaves one or two candidates once the surrounding patches are placed.
Any rectangle you draw must contain exactly one clue. That rules out a great many shapes instantly: if a candidate would swallow a second clue, it is dead, whatever its size.
A six-cell rectangle is 6x1, 3x2, 2x3 or 1x6, and the shape icon usually eliminates half of those. A five-cell rectangle only has 5x1 and 1x5 — prime numbers are the easiest clues on the board.
If a cell cannot be covered by any rectangle from any remaining clue, one of the patches you already placed is wrong. Back that one out rather than forcing the rest around it.
Every clue shows its number, so the numbers always add up to exactly 36. Use that as a check: once most rectangles are down, the cells left over must match the numbers of the clues still waiting.
Tapping a drawn rectangle removes it and costs nothing but a move. Shikaku has no fail state and no life counter — the only thing being measured is the clock.
