How to play

  1. Press Start Round or hit Space.
  2. Each turn shows one square and speaks one letter.
  3. If the square is in the same position as it was N turns ago, press V or click Position Match.
  4. If the spoken letter is the same as it was N turns ago, press A or click Audio Match.
  5. Only press a match button when there is actually a match. Guessing wildly is allowed, but the score will judge you, as scores rudely do.
