Ink Seven

Collect exposed scroll tiles into a seven-slot tray; triples vanish. Each lower tile needs its two covering tiles removed: directly above and one column clockwise, wrapping at the right edge. A one-tile brushcase can stow the newest tray tile and return it later. Clear every layer, tray and brushcase without collecting seven unmatched tiles.

Tap controls, or Tab then Enter/Space. R restarts. Every action is turn-based; take time to plan.

Seven-slot triple collection; a small original character set, not a dictionary course.
