How to play

A field of closed tiles hides some mines. Open every safe tile and you win. Open a mine and the round is over.

Numbers

An open tile shows how many mines touch it, counting all eight neighbours, diagonals included. A blank tile has no mines around it, so the game opens its neighbours for you.

Controls in Sweeplight

• Tap a closed tile to open it.
• Press and hold to place a lantern (a flag) on a tile you know is a mine. You can swap tap and hold in Settings, or use the Flag mode button.
• Tap a number whose lanterns are all placed to open the rest of its neighbours at once (a "chord").
• Pinch to zoom and drag to move around bigger boards.

No-guess boards

Classic Minesweeper sometimes leaves you with two tiles and no way to know which one is safe. Sweeplight checks every board with a solver before you play it and only keeps boards that can be finished by logic from the opening. If you are stuck, there is always a safe tile somewhere; the Hint button shows it, with the numbers that prove it.

The Journey and its rules

Levels grow slowly and a boss waits every ten levels. Along the way new rules appear, each introduced with a short demo:

• Fog: some numbers hide behind a question mark until most of their neighbours are open.
• Timed: a clock counts down; the time grows with the size of the board.
• Ice: frosted tiles take two taps, one to crack the ice and one to open the tile.
• Locked ground: a shadowed band opens only when everything else is clear.

Stars: one for a clear, two for a clear without hints, three without hints, without a Second Chance and within the target time.

Daily, Weekly and more

The Daily is the same board for every player in the world and changes at 00:00 UTC. Clear it each day to build a streak; one free streak freeze a month covers a missed day. The Weekly is a big board for the whole week, the Special uses one of the Journey's rules, Time Attack gives you three minutes for as many small boards as you can, and Zen has no clock at all.
