More ground to cover. More connections to discover.
A new daily set is ready.
Swipe sideways to explore the field, or choose Fit board.
Open the leaf to begin. Your first opening is safe.
Right-click or hold a tile to flag. Keyboard: arrows to move, Enter reveal, F flag, H hint.
Hard contains 256 tiles and 45 mines. It gives you more clues and boundaries to keep track of. Each accepted board still has a complete logical path from its safe opening, using local clues, overlapping groups and the total number of mines.
On a small screen the field can scroll sideways to preserve larger tap targets. Use Fit board to see the whole field, or Large tiles for roomier controls. A Flag mode button lets you mark mines without using a right mouse button.
There is no countdown or limit on breaks. Pause covers the field, and time spent in a hidden tab does not count. A hint can reveal a reasoning step, and your shared result includes any hints or recoveries from a mine hit.
