About Command Memory
A memory game with commands. Look, remember, then match each command with what it does, or type it from memory.
Command Memory uses only commands from the free lessons, level by level. Play it free in your browser, with no ads and no sign-up.
Guide How to play
- Pick a deck and press Play. The cards show for a moment: commands on dark cards, what they do on light ones.
- The cards turn over. Flip two: a command and what it does make a pair. Two that do not match turn back over, with nothing lost.
- Flip a light card and you can type its command from memory instead. Type it right and its pair is yours, with a bonus.
- Stuck? Press ? or Peek to see every card again, twice a round. Match every pair in the deck to finish.
- No mouse needed: the arrow keys move between cards, and Enter turns one over.
Command Memory practises remembering what each command does, and entering it from memory. Knowing what a command does before you press Enter is the first rule of the terminal.
