The game of mahjong requires four players, 144 tiles and two dice to roll. It's important to note, however, that there are variations in how the game is played from country to country. The goal of mahjong is similar to poker, in that the aim is to make matching sets and pairs.

Poker is a card game that typically involves betting and individual play, with various hands ranked according to the probability of their occurrence. On the other hand, mahjong is a tile-based game that originated in China and involves skill, strategy, and a degree of chance.
