Chromatic Brackets

Restore three mint ■ rows AND three amber ◆ rows within 30 domino drops. Tap any cell to choose its column. Rotate changes horizontal/vertical orientation; Reverse pair swaps its two fixed colours, not the whole palette. The dashed landing and forecast show exactly what your drop will do.

A new tile flips an uninterrupted straight run of rival tiles when another tile of its own colour brackets the far end. Empty gaps stop the bracket. Both new domino tiles stay protected during that drop. Only full, single-colour rows disappear; remaining rows shift down intact.

Corner colours matter: they cannot be bracketed from outside the board. Select an occupied left or right edge tile and Brush edge to repaint it. Start with one charge; each balanced pair of mint/amber rows restores one, up to two. Brushes do not spend dominoes. A blocked drop spends nothing. Arrow keys focus cells; Enter selects. Restart repeats a seeded challenge; reload starts a fresh one.
