The strike ratio for when you hook a ball is far less than reality and you'll leave a flat 10 nine times out of ten. Bowl straight and youll strike nine times out of ten. That makes the game boring quickly and just like every bowling game. Game is also unrealistic as balls can travel up to 30 miles per hour; even PBA pros only get about the low 20s. The game is also heavily ad driven until you make an in-game purchase.
