Sushi Sudoku

You control the cursor, clicking on empty squares to place a piece of sushi from a selection tray. The core objective is to fill the nine-by-nine grid so that each row, column, and three-by-three block contains every type of sushi exactly once. The game often provides a few pieces to start, and you spend your time scanning the rows and blocks, figuring out which piece can logically fit in a given spot. The pace is methodical, and the difficulty comes from the initial puzzle setup rather than any time pressure. It feels like a quiet, focused exercise in pattern recognition.
