Mahjong Calling by ASM Games is a card-based adaptation of the classic tile game. The rulebook guides players on forming winning hands using cards instead of tiles. Players aim to create sets of pungs, kongs, and chows, along with a pair, to complete a 14-card hand. The game follows traditional Mahjong mechanics, including drawing and discarding cards, calling for discards, and declaring “Mahjong” to win. The rulebook likely covers card types, hand formations, scoring, and special hands, adapting the rich strategy and gameplay of Mahjong to a card format.
