How to play
Choose the aroma seals to complete the empty spaces, then click «Check code». Analyze the response in comparison with your earlier tries. In Simple mode, ✓ indicates a correctly placed seal, shows that the seal is in the wrong place, and — signals that it's either missing or a repeated extra. Classic mode provides the overall count of correct matches.
Discover the code before you exhaust your attempts. «Undo» will remove the last seal added, while «Clear» will reset your current attempt. On a computer, use the numeric keys to pick seals, Enter to verify the code, and Esc to pause. On mobile devices, simply tap the controls. To switch languages, go to «Language» in the menu.
