What Hamdoku is and who it suits

Hamdoku uses the deduction of Sudoku but drops the digits. The board is split into colored regions, and you fill it with hamsters instead of numbers. The store summary also describes it as a Queens-style puzzle, which fits the same idea of one piece per row, column and region.

It suits people who like Sudoku-style logic and want the same kind of thinking with a softer look. The listing rates it for ages 3 and up.

Placement rules for the hamster grid

Each colored region, each row and each column must hold exactly one hamster. On top of that, no two hamsters may touch, including diagonally. The two rules work together, so a placement that satisfies the region and line rules can still be ruled out by a neighbor.

The listing describes the rules as quick to learn, with the harder part being the deduction needed to finish a board.

Sunflower seeds, hints and notes

Each puzzle gives you three sunflower seeds. A wrong placement costs one seed, so you have three mistakes to work with. Hints are available when you get stuck, and notes let you mark possible spots without committing to them.

The seeds act as the only error allowance the listing mentions, so the notes and hints are the main way to test a guess before you make it.

Daily puzzles, streaks and timed play

A new puzzle arrives every day. Solving the current day's puzzle keeps your streak going. A stopwatch runs during play, and the listing says you can try to beat your personal best time.

The daily format gives the game a fixed schedule, with one puzzle per day to return to.
