Aiming Ball: How to Read It

The Aiming Ball (ABall) provides guidance on how to strike the cue ball to achieve the intended result shown in a drill. It communicates two things:

  1. Stroke speed
  2. Tip position (spin and follow/draw)

(1/2 tip of right English, 1 tip of follow, speed of 2-1/2 tablelengths)

The Aiming Ball is a teaching aid. It is meant to guide execution, not replace decision-making.


What the Aiming Ball Represents

An Aiming Ball shows:

  • Where to strike the cue ball
  • How hard to hit the shot

Different equipment and strokes may produce slightly different results, but following the Aiming Ball guidance will help you execute the shot as the drill designer intended.


Speed Indicator

The speed indicator shows the recommended cue ball speed for the shot.

  • Speed is shown on a numeric scale from 0.25 (very soft) to 6 (very hard)
  • A speed of 1 corresponds to one table length
  • A speed of 2 is roughly a typical lag shot (down-table and back)
  • Many drills rely on speed control for correct cue ball position

Speed Control drills are provided to help you calibrate your stroke to your table and equipment.


Tip Indicator (Spin and Follow/Draw)

The tip indicator shows where to strike the cue ball.

There are two supported display formats.


X / Y Format (Default)

  • X value → left/right English (side spin)
  • Y value → follow or draw (top/bottom spin)
  • Values are shown in tips

Example:

  • X = 0.5 → half tip of right English
  • Y = 1.0 → one tip of follow

Clock Format (Optional)

The Clock format represents tip position using:

  • O’clock position
  • Number of tips

This format can be selected in Settings → Aiming Ball Style.

Both formats represent the same information; choose the one that is easier for you to visualize.


Showing and Hiding the Aiming Ball

  • Press A to toggle the visibility of the Aiming Ball
  • Hiding the Aiming Ball is useful if you want to:
    • Analyze the shot on your own
    • Test your understanding before checking guidance

Important Usage Notes

  • Not all drills include an Aiming Ball
  • Some drills intentionally omit the Aiming Ball to encourage problem-solving
  • When Statistics is active, the intended speed/spin may be captured for analysis
  • The Aiming Ball does not account for every equipment or cloth variation — it is guidance, not a guarantee
