Jade Rush. Mahjong solitaire raced against a rival and a draining clock. Tap or click two matching free tiles to clear them: a tile is free when nothing rests on it and one long side is open. On a keyboard, move between playable tiles with the arrow keys or W A S D, select with Space or Enter, and press H for a hint. On a gamepad, use the d-pad with the primary button to select and the secondary button for a hint. Chain matches quickly to build the surge meter and trigger Dragon Rush, which freezes the clock. Clear the pile before your rival clears theirs. Add motion=reduced to the address to soften the effects.
