Mind Gym: Reaction Memory Test

Mind Gym — 13 quick brain games: reaction time, memory, Chimp Test, math and typing 🧠

Mind Gym puts 13 short brain tests in one app. Check your reaction time in milliseconds, see how much your memory can hold, beat the Chimp Test, race the clock in math and typing, and climb the weekly and all-time top 50 in every game. Each game takes about a minute, so it fits in any break.

⚡ SPEED
• Reaction Time – wait for green, then tap. Three taps, one average in milliseconds.
• Aim Trainer – hit 30 targets that get smaller as you go.
• Typing Speed – type as fast as you can for 30 seconds and see your words per minute.
• Math Sprint – answer as many sums as you can in 60 seconds. They get harder as you score.

🧠 MEMORY
• Number Memory – a number shows, then hides. Type it back. One more digit each round.
• Letter Memory – the same test with letters.
• Visual Memory – squares light up on a grid. Tap the ones you saw.
• Sequence Memory – watch the pattern, then repeat it in order.
• Chimp Test – tap 1 and the numbers turn blank. Tap the rest in order from memory.
• Verbal Memory – words show one at a time. Seen it before, or new?

🎯 FOCUS
• Color Confusion – the word says GREEN but the ink is red. Don't let it fool you.
• Not Not – "not left" means anything but left. Think fast before time runs out.
• N-Puzzle – slide the tiles of the classic 15 puzzle into order and beat your best time.
