Mines
A fast-paced minesweeper-inspired cognitive game where numbers flash briefly. Memorize clues, deduce safe tiles, and clear the board.
Overview
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.

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