24 lessons covering pool, 9-ball, and snooker — from aiming to position to safety. Every shot you fire gets a diagnostic readout: actual cut angle vs ideal, cue-ball error, what to fix next time.
Ghost ball, contact point, cut-angle arc — overlaid in real time on the table. Stop guessing; see where the cue ball must go before you shoot.
The instant your shot lands, you get the numbers: "Cut too thick by 5.3° (actual 24°, ideal 30°)". No more "I don't know why I missed."
Per-lesson stats show whether you systematically cut thick, thin, or aim off entirely. See the bug before you fix it.
From aiming fundamentals to game-specific tactics for pool, 9-ball, and snooker. Every lesson grounded in the WPA / WPBSA rule books and Dr. Dave Alciatore's billiards.colostate.edu — not invented from scratch.
Ghost ball, contact point, fractional aim. Three industry-standard methods + 4 progressive drills.
Three points in a line. The foundation of every cut.
Anchor: 30° = 1/2 ball. The reference cut every player must master.
60° razor-thin cuts. Precision over power.
Estimate cut angle from visual overlap. Train your eye.
Two laws that decide where the cue ball ends up. Stun and rolling, in order.
Plan the last three balls first. Capelle's #1 principle.
When the tangent line points the wrong way — bounce the cue ball back.
Fold the table mentally. Aim at the virtual pocket.
1-rail banks via simple cushion arithmetic.
Strike point decides forward, stop, or reverse.
Three effects: squirt, swerve, throw. Two work against you.
A tool, not a default. Running, check, and gearing English.
When even banks fail. Rules vary wildly across game types.
The "magic" curve shot. Where physics gets weird.
Why 9-ball punishes greedy shots. Forced lookahead.
Wing ball + squat the rock. The most important shot of every rack.
9-ball's secret-weapon rule. Most under-used legal weapon at the amateur level.
Plan 7-8-9 first. Phil Capelle's "22 Principles of Position."
Distance, angle, snooker — in that order. You don't need a snooker to win.
12-ft table, 52.5mm balls, tighter rounded pockets. Same physics, different geometry.
Reds, colors, respots, and the 147 break. WPBSA rules in 10 minutes.
The other half of the game. Why snooker frames aren't won by potting alone.
Start at 1.1 if you're new. Pros can jump straight to Chapter 5 or 6.
Diagrams + key points first, then drills on the simulated table. ~10-15 min per lesson.
"Cut too thick by 5.3°" or "Hit the OB cleanly, scratched the cue ball." Specific, actionable.
Each lesson has a pass threshold (typically 70%). Progress saved locally.

No — but it can teach you the geometry and physics that most players never explicitly learn. Real-table practice combined with this app's diagnostic feedback is faster than either alone. The simulated cue ball obeys the same 90° tangent and 30° rules as a real one.
Yes for fundamentals (Chapters 1-4 — aiming, cue ball control, follow/draw, English are universal). The tactical lessons in Chapter 6 cover snooker-specific rules and safety play. The simulator currently uses a 9-ft pool table, so practice geometry approximates rather than replicates a 12-ft snooker table — concept-first, with explicit notes on differences.
Chapters 1-4 cover everything you need for 8-ball. Chapter 5 (9-ball tactics) overlaps significantly — pattern play and safety hierarchy apply to both formats.
Yes. The roadmap includes: full physics for jump shots and massé, more 9-ball break configurations, and 10-ball tactics. Existing lesson errata get corrected as the underlying research is updated.
Every physics claim is grounded in the WPA / WPBSA rule books, Dr. Dave Alciatore's billiards.colostate.edu, Phil Capelle's Play Your Best 9 & 10 Ball, and Bob Jewett's instructional column work. We cite where it matters.
