Twinwell Accord
Left and Right cooperate to clear THREE same-color pairs each. Players alternate after each drop; tap one of the active player’s two lanes. Equal colors at the same height clear together; mismatches remain. Trade the next rune with the SHARED center bridge once per turn to save a color for your partner. Retrieve a stored rune after the queue ends. Completed wells yield turns to the other player. Limited rune supply and overflowing columns can end the accord.
Tap tiles, or use Tab and Enter. Arrow keys move board focus.
