Why play logic puzzles
A logic puzzle is a small, closed problem. The rules are few. The board is finite. One solution is waiting.
You play to sit with that. To find the next forced mark. To feel the grid tighten until there is nothing left to decide.
It is not a test. It does not promise anything about memory, mood, or how sharp you are. The pleasure is ordinary: a quiet stretch of attention, a unique finish, and the option to stop.
On this site that sit is Sudoku, Star Battle, or Binary Puzzle. Open one when you want it. Close it when you are done.
