How it works

• Click to place one tessera. Brush to sweep. Space or right-drag to pan.
• Wash is free. Ink buys Metal (a day) and Gem (three days).
• Held cells block other painters. You can overwrite your own after a confirm.
• Undo a stroke for 30 seconds (⌘Z) and the ink comes back.
• Fought-over cells cost more. Boards last two days.
