Spotty Condition:

Try to play straighter! Ball selection is a key in conquering various lane conditions. For example, a urethane ball is preferrable for spotty
conditions since it does not "overreact."

Reversed-block Condition:

Try to play straighter! Ball selection is a key in conquering various lane conditions. For example, a urethane ball is preferrable for spotty
conditions since it does not "overreact." The reverse block is not normally created deliberately and is very hard to play. So, to combat the
open-play the center will put more oil in the middle part of the lane.

Walls, Blocks & Top Hats Conditions:

This lack of oil on the outside created a wall of friction. If a hook bowler missed the target a few boards to the outside the extra friction
in that part of the lane would bring the ball back - on flat oil it would probably slide on, or even off the edge of the lane! A wall is clearly
a very high scoring shot.

Christmas Trees Conditions:

This is the fairest possible condition. The Christmas Tree tries to cater to all styles, allowing the cranker to move inside and swing the ball
out to the break point while, at the other extreme, the low-rev hook bowler can play up the outside lines.
