Mem Blitz Games
Three Ways to
Challenge Your Mind
Each game targets a different cognitive skill — spatial memory, inhibitory control, and working memory.
Spatial Memory
Directions
Four arrow buttons — up, down, left, right. The game flashes a sequence of arrows, and your job is to tap them back in the exact same order. Each round you survive, one more arrow is added to the chain.
Round 1: One arrow appears. Tap it back.
Round 2: The first arrow replays, plus a new one. Tap both in order.
Round N: The sequence keeps growing. One wrong tap ends the game.
Inhibitory Control
Color-Word
A color name flashes on screen — but it's written in a different ink color. Your brain wants to read the word; your job is to ignore it and tap the tile that matches the ink instead. Simple to understand. Surprisingly hard to execute.
A word appears — for example, "RED" — written in green ink.
Ignore the word. Look at the ink color. In this case: green.
Tap GREEN on the grid of four color tiles — before time runs out.
Based on the Stroop Color and Word Test, first published by John Ridley Stroop in 1935. It measures cognitive interference — your brain's ability to override a dominant automatic response.
Working Memory
Numbers
A sequence of digits flashes on the watch screen, one at a time. Once they've all appeared, you reproduce the sequence on a full numpad. Every correct answer adds one more digit to the next round.
Round 1: A single digit appears. Enter it on the keypad.
Round 2: Two digits flash in sequence. Enter them in order.
Round N: The chain grows by one each time. One mistake ends the game.
Based on the digit span task, a staple of cognitive psychology since 1887. The average adult can hold 7 ± 2 digits in working memory — can you beat it?
