Ten by ten is the size most shikaku books settle on, and for good reason: a hundred cells is enough room for a long chain of deductions without the grid becoming a chore to draw. Expect large clues like 12 and 15 that stretch across a third of the board, and small 2s and 3s tucked in corners that quietly decide where those big rectangles are allowed to sit. Most solvers work these in twenty minutes or so once the puzzle is familiar.

Each page carries one 10x10 shikaku grid with clean rule lines and clue numbers large enough to read at arm's length. Cell size is kept generous so drawn rectangle borders stay legible even after a few corrections. Every puzzle has an answer page showing the completed tiling. All sheets are black and white and fit a single US Letter page.

Frequently asked questions

What is a good strategy for a 10x10 shikaku?
Work from the constraints inward. Clues on the edges and in corners have fewer legal placements, so start there. Then look for cells that only one clue can possibly reach — often a cell hemmed in by other rectangles — and grow that clue's rectangle to cover it. Large prime clues like 11 or 13 are forced into a single straight line, so place them early.
Do the clue numbers in a shikaku always add up to 100 on a 10x10?
Yes. Because every cell belongs to exactly one rectangle and each rectangle's area equals its clue, the clues must sum to the total number of cells. Adding them up is a quick way to check you have read the grid correctly, and it is a neat arithmetic exercise if you are using these with students.
Is shikaku harder than sudoku?
It is different rather than harder. Sudoku asks you to eliminate candidates cell by cell; shikaku asks you to think in areas and factor pairs. People who find sudoku repetitive often prefer shikaku, and people who like the tidiness of sudoku sometimes find shikaku's open-ended shape choices uncomfortable at first.
Can I print these double sided?
You can, but keep the answer pages separate if the puzzle is for someone else — printing single sided, or printing the puzzle pages first and the answer pages as a second batch, avoids a solution showing through thin paper.
