How do I play?
Choose Fill and tap a segment. Potion fills from the round bulb to that segment. Choose X to exclude a segment and everything after it; Erase returns the whole tube to Unknown. Match the row and column totals, and decide every segment to finish.
What does A + B = 5 mean?
The two tubes labeled A and B contain five filled segments in total. Letters identify tubes, not colors. Combine this recipe with the row and column clues.
Can I undo a mistake?
Undo and Redo keep your last 100 moves. Reset asks for confirmation and can also be undone. Hints explain a deduction and never use money or consumable credits.
Offline play and settings
All 120 puzzles work offline. In Settings, you can change sound, haptics, and English or Traditional Chinese. Motion follows the device’s Reduce Motion setting.
