🃏Play Memory Match

Memory Match — concentration, pelmanism, pairs, depending on where you grew up — is the simplest possible test of visual working memory, which is exactly why it has survived as a children's game, a cognitive test and a coffee-break distraction all at once.

The interesting part is that the optimal strategy is not to remember everything. It is to gather information cheaply early, then cash it in. A player who spends the first few moves deliberately revealing unknown cards in a fixed order will usually finish in fewer total moves than a player who tries to match immediately.

This board uses eight bright symbol pairs on a four by four grid, which is the size where the game is quick but not trivial. A perfect game is eight moves; a good game is under twenty; most first attempts land in the mid twenties.

There is no timer, deliberately. The pressure in this game should come from your own move counter, not from a clock that punishes thinking.
