Pro Mahjong Tsuwamono GB2 — About this game
Look for a realistic route to a scoring hand while watching the discards around the table. Calling a tile can complete a set quickly, but it also reveals part of your hand and may remove a potential scoring pattern. When an opponent looks dangerous, protecting your points can be better than chasing a distant win. Start with simple concealed hands before relying on frequent calls.
