How to play
Choose four symbols, then submit. Use the clues to find the hidden code.
Exact = right symbol, right slot. Misplaced = right symbol, wrong slot.
Clues are totals, not slot markers. Each symbol counts once; repeats need repeated matches.
Easy: all guesses stay visible. Medium: four permanent reveals per game. Hard: no past guesses. In Medium and Hard, your latest result stays until you place the next symbol. Changing difficulty starts a new code.
Keyboard: 1–6 to place, ← → to select, Backspace to erase, Enter to submit.
