Sudoku

How Sudoku plays: Most boards hide a sequence: clear space, unlock a chain, then convert that opening into the objective. Rushing usually creates dead ends, while patient scanning reveals the efficient path. Dead ends usually come from greedy early moves that block the only efficient path. In Sudoku, the sudoku fantasy is the hook — lean into that fantasy instead of treating every round like a generic Logic template.

Difficulty ramps teach systems first, then demand cleaner execution. Parents often prefer these over combat titles for short shared sessions.
