Memory Card Game

Match pairs across 4 modes with a brain fatigue twist that speeds up flip-backs.

Memory Card Game

Pick a mode. Brain fatigue makes cards flip back faster as you go.

About Memory Card Game

Classic memory card matching game with four modes: Classic (no pressure), Time Attack (90-second deadline), Hardcore (5 lives), and Infinite (each level adds more pairs). Tracks moves, match streaks, and best scores per mode in localStorage. Includes a brain fatigue mechanic — the longer you play, the faster cards flip back, forcing you to lock pairs into memory faster.

How to Use

  1. 1Pick a mode from the menu — each has its own best-score record.
  2. 2Click any two cards to flip them. Match the symbols to keep them face up.
  3. 3Build streaks by matching pairs consecutively without misses.
  4. 4Watch the flip-back timer — it gets faster the more moves you make.
  5. 5Match all pairs to win the level (or beat your previous best).

Frequently Asked Questions

What modes are available?
Classic (8 pairs, no pressure), Time Attack (10 pairs, 90-second timer), Hardcore (8 pairs, 5 lives), and Infinite (starts at 6 pairs and adds one more pair each level you clear).
What is brain fatigue?
The longer you play, the faster mismatched cards flip back face-down. Flip-back time decreases by 15 ms per move (down to a 300 ms floor), simulating cognitive fatigue.
Are my best scores saved?
Yes — best scores per mode are saved in your browser's localStorage. Nothing is sent to any server.
How is the score calculated?
For Classic, Time Attack, and Hardcore: score = (pairs × 10) − moves. For Infinite mode: score = highest level reached.
