Pro Mahjong Tsuwamono GB — About this game
The first Tsuwamono GB focuses attention on the choices inside a mahjong hand: which shapes to preserve, when a call is useful and whether another player's discards suggest danger. Keep your plan flexible when the draw changes it. A concealed hand is a useful starting point because calling too early can narrow the scoring patterns available. Learn to recognize a valid win before increasing the pace.
