Domino Stack

Face-down tiles fill the reserve in Domino Stack. Four face-up dominoes sit in the middle, forming four trains with eight playable ends. The full set has 28 pieces, and the layout asks for every tile to leave the reserve and join those lines before play stalls.

How to play?

Draw from the stockpile one domino at a time. Place each piece on either end of a train when the numbers match. Up to four ends may accept a move during play. A round stops the moment no train can take the next domino. Lay all 28 tiles onto the four trains to win.
