Settings
Skin
Changes the frame only. The puzzle field stays neutral grey in every skin, so scores compare.
Motion
Controls the rosette and panel movement. Puzzle timing is never affected.
Round clock
Timed rounds start at Medium. Turning the clock off makes scores easier and not comparable.
Colourblind-safe palette
Swaps the afterimage room to a blue–yellow axis and drops red–green pairings.
Screen check
Two rooms depend on your display being honest. Turn off auto-brightness and Night Shift, then raise brightness until every band below is distinct — especially the dark ones at the left.
If the first three bands look identical, the Hard tier is unwinnable on this screen rather than merely difficult.
Turn your phone sideways
The parlor is built wide. If your device has rotation locked, unlock it from Control Centre.
