How to play
Open every lens
Tap the die once to begin, then select a closed lens. Matching colours stay open. A wrong colour is visible for the selected time before closing; the die rolls automatically as it closes. Remember the colours you have seen.
Automatic turns
Only colours behind at least one closed lens can be rolled. Each remaining colour is equally likely. Tap the die once to begin. After a wrong guess it rolls automatically. After a match, your setting either keeps the same colour or rolls again. Once all lenses of a colour are open, that colour is excluded from future rolls.
At your pace
Choose the board size, what happens after a match and how long a wrong lens stays open (0.5–3 seconds), show the timer or reduce animation. Only a board-size change starts a new round after confirmation.
A complete spectrum
Open every lens to finish. All six colours are distributed as evenly as possible. Once all lenses of a colour are open, that colour can no longer be rolled. There is no time limit.
Private saved games
Open Game information → Saved games to save, load or delete a private round. At the end choose Yes or No to save, then select a slot and confirm with OK. Finished rounds cannot be continued. A wrong guess resets only the current streak; the longest streak remains saved. Menus and background time do not count.
