Join Unicorn, Mari Lwyd, Kelpie, Pegasus, and dozens of other horses from myths. Merge gems into creatures, creatures into magic ponies, and ponies into legends, and ride them up the mountain of mystical dreams! Merge Mountain is a family weight resource management. Cards grant powers and move you tracks on the mountains. When a player makes a big enough herd or reaches the top, the game ends and points are counted.
