Honkaku Yonin Uchi Mahjong - Mahjong Ou — About this game
Start by identifying likely groups and a pair, then look at the visible discards before committing to a direction. Calling a tile can speed a hand but also changes its structure. Keep the current score in mind when deciding whether to keep pushing or choose a safer discard.
