Logic games have no luck in them once you know the rules — every board can be reasoned out. They look exactly like concentration from across the office, because they are.
Best times are tracked per difficulty, so your Expert clear never gets buried under Beginner practice runs.

Logic games are the respectable end of the office break: a grid, a set of rules, and a solution that can be reasoned out every single time. There is no reflex to train and no luck to curse — just deduction, concentration and the occasional very bad click. They look exactly like work from across the room, which has historically been the point.
Both games here are ranked by time, per difficulty, and only clean solves count (no hints, no guesses that happened to work). The house target for each board is a brisk time we set as a benchmark; your own best is kept in this browser and nowhere else unless you opt in to the tops.
- Minesweeper The game that shipped with every office PC for a reason. Beginner to Expert.
- Sudoku Looks exactly like work from across the room. Easy to Expert, saves mid-puzzle.

Questions from the floor
Why are Minesweeper and Sudoku ranked by time?
Because a correct solve is the baseline — the interesting question is how fast. Best times are kept per difficulty so an Expert clear is never buried under Beginner practice, and only hint-free, flag-honest solves count for the tops.
Does Sudoku have pencil marks and undo?
Yes. Toggle pencil mode to note candidates in a cell, undo any step, and the puzzle saves itself mid-solve. Using a hint still lets you finish, but the time will not qualify for the leaderboard.
How do I flag a mine on a touchscreen?
Long-press a cell to place a flag, tap to reveal. On a laptop, right-click flags. Chording — clicking a satisfied number to clear its neighbours — works with both mouse buttons or a two-finger tap.
