TLS Brain Training has three memory puzzles:
Animal Sounds
This game is based on the classic “Simon” game from the 1980s. The player needs to listen to a sequence of sounds made by animals and then repeat it.
One sound is added at each stage until the player makes a mistake. The animals light up as they make the sounds, so it is possible to play with the sound muted.

The classic memory game adapted to one player. You are given a set of face-down cards and must match pairs from the set in the shortest possible time. There are three possible sizes of grid, from small (5x4) to large (7x6).
