Shots, Trajectories, & Statistics in Classic Mode
Analyze your bowling performance like never before! This section explains the statistics, lane trajectories, and interactive features in Classic Mode.
Interactive Features
Rearrange & Swap Tiles:
Hold down on the tiles to move them or swap them out for other metrics! Customize them to prioritize the stats that matter most to you.
Shot History Navigation:
Near the top, where it displays your shot number, you can easily revisit previous shots and delete them if needed. To delete a shot, hold down on the number!
Filter Lane Trajectories:
By holding down on the lane diagram, you can select which trajectories you want to view—strikes, spares, missed strikes, or any combination thereof.
View Metric Trends:
Click on any tile to open a detailed graph showing that statistic’s trend throughout your session. Observe how it changes—or remains consistent—across your throws!
By default, Spares, Made Strikes, and Missed Strikes are all enabled!
On the lane, each shot appears in a distinct color. Green shots are a strike, blue shots are missed strikes, and black shots are spare attempts.

Foul Line
- This statistic shows the board where the bowling ball crosses the lane at the foul line.
Arrows
- This statistic shows the ball’s board position when crossing the arrows (e.g., board 7.5 or board 9.0), offering a numeric reference for initial aim and alignment.
Entry Board
- The entry board is the specific board number at which the ball enters the pocket (the headpin and its adjacent pin).
The ideal entry board is commonly board 17.5 for right-handers.
Hook Factor
- Hook factor describes the degree to which a bowling ball curves or “hooks” as it travels down the lane.
- Quantified by measuring the rate of lateral acceleration during the ball’s hook phase, in boards per second squared.
Breakpoint Board
- The breakpoint board is the lane board where the ball reaches its maximum lateral deviation before hooking back toward the center of the lane.
Breakpoint Distance
- Breakpoint distance is the linear distance from the foul line to the point where the ball reaches its breakpoint.
- It tells bowlers how far down the lane the ball travels before beginning its hook.
Launch Angle
- Launch angle is the initial angle at which the ball leaves the bowler’s hand relative to a line parallel to the lane’s boards.
- A zero-degree launch angle means a straight path, whereas a positive angle causes the ball to start curving either inward or outward.
Impact Angle
- Also called the entry angle, impact angle is the angle at which the ball contacts the pins as it enters the pocket.
The optimal impact angle is 6 degrees.
Launch Speed
- Launch speed is the velocity of the ball at the moment it is released by the bowler.
- It represents the highest speed the ball achieves during its journey down the lane, before friction slows it down.
Impact Speed
- Impact speed is the speed of the ball at the moment it strikes the pins.
Average Speed
- Average speed is the overall speed of the ball calculated over the entire distance from release to pin impact.
Hook Boards
- Hook boards describe the number of lane boards the ball moves laterally from its breakpoint to the point of entry into the pocket.
Max Speed Loss
- Max speed loss refers to the point along the lane where the ball experiences its greatest reduction in speed—typically the moment when the ball’s reaction transitions from smooth skid to aggressive hook.
Speed Loss
- Speed loss is the overall reduction in the ball’s velocity from the moment of release to when it hits the pins.
Shot Time
- Shot time is the total time elapsed from when the ball is released until it strikes the pins.
RPM
- This statistic is calculated by LOOKING at your ball and determining how fast the rev rate is in RPM!
