How times are counted.
The timer starts when your first opening is ready, so board generation time is excluded. Pausing covers the board and stops the clock. Switching away from the page pauses the game too.
Only unassisted, non-replay wins set records. Classic and no-guess times are separate. These are personal, pausable game times, not verified competitive speedrun scores.
Custom records and game statistics.
Custom records use the exact row count, column count and mine count. No flags records are kept separately, as are Classic and no-guess games. Seeded, shared, imported and authored boards are practice.
Advanced statistics count successful state-changing actions, not every physical mouse click. 3BV counts the minimum reveal clicks needed without flags or chording: one for each empty opening and one for each remaining safe numbered square. 3BV per second divides that value by active game time. These values appear after a round.
The game has 16 achievements based on saved local results. See the achievement requirements and the complete options reference.
