ANGLE DETECTIVE

Angle Recognition Training Game for Pool and Snooker

Designed to build transferable skills you can take to the real table, Angle Detective is a unique billiards game that trains your ability to see and recognize shot angles through repeated visual problem-solving. 

Unlike traditional billiards games, Angle Detective is a puzzle-based training game built on precise 3D geometry. Every shot challenges you to identify the correct angle before the game reveals the true solution.

An invaluable Practice Mode lets you choose any angle between 0° and 90° and visually ingrain it by clicking through infinite randomized shot layouts.

Designed for pool and snooker players of all levels — and for anyone who enjoys visual geometry puzzles.

Companion Book

Angle Detective is the companion video game to ANGLE DETECTIVE: Radical Methods for Solving the Shot Angle Mysteries of Pool and Snooker — a new instructional book that explains the visual guides used in the game and teaches how to apply them, along with many novel shot-angle recognition tools and methods. Please visit AngleDetective.com for links to the book as well as links to download 17 free precision printable training tools you can take to the table.

What Makes Angle Detective Different

• Not a physics game — an angle-recognition training game

• Infinitely randomized gameplay

• Accurate ball and table geometry

• Clean, focused interface — no ads, no internet required
  
  

Play Modes

Amateur Play Mode
All tools and camera views available with no restrictions.

Professional Play Mode
Restricted tools and camera views simulate real match conditions.
After scoring, the shot can be freely replayed and studied with no restrictions.

Practice Mode
Choose any angle from 0°–90° (in 0.1° increments) and the game continuously generates geometrically accurate randomized layouts at that exact angle — ideal for deeply ingraining angle recognition. You can even raise or lower the view to match your real-life eye height, then click through shot after shot while the view remains at the same height you would have at a real table.
