Basic Rules
Memorize numbers that flash briefly, avoid mines, and open all safe tiles. Tiles with no adjacent mines auto-expand in a chain.
A fast-paced minesweeper-inspired cognitive game where numbers flash briefly. Memorize clues, deduce safe tiles, and clear the board.

Flash Mines is a fast mines puzzle where numbers flash briefly and then disappear. Memorize the clues, deduce safe tiles, and open all safe tiles. Tiles with no adjacent mines auto‑expand, and hints can be used without limit. As stages increase, the board grows, mines increase, and the flash time gets shorter.
Memorize numbers that flash briefly, avoid mines, and open all safe tiles. Tiles with no adjacent mines auto-expand in a chain.
A number indicates how many mines are in the surrounding 8 tiles. Use it to deduce safe tiles.

Because numbers vanish within seconds, you must perceive information quickly and make rapid decisions—training processing speed.
You need to hold the displayed numbers and positions briefly, strengthening short-term retention and working memory.
Numbers indicate how many mines surround a tile. Inferring safe tiles from these clues trains logical reasoning.
Choosing when to use hints and which tiles to open requires deliberate control and attention switching.
