# The game beneath the game.

A practical reference for the forces, geometry, and choices that shape cue-ball behavior.

### Diamonds

How rail markers create repeatable references for banks, kicks, and route planning.

### Throw

Why object balls can be pushed off the pure geometric line by friction and spin.

### Squirt & Deflection

What changes when the cue contacts away from center and why equipment matters.

### Speed Control

How pace changes pocket acceptance, rail response, and final position.

### Natural Angle

Using the tangent line and rolling-ball behavior to predict cue-ball departure.

### Pattern Play

Choosing routes that create larger position zones and fewer difficult recoveries.

Launch edition: This public knowledge base establishes the curriculum map. Full lessons, diagrams, and replay examples will be released as the recovered training application is validated.

## A useful rule

Before adding spin, establish what center ball and speed alone will do. Spin is most useful when it solves a specific route problem—not when it is added out of habit.

## Another useful rule

Plan position as an area rather than a dot. Larger zones create simpler shots, wider margins, and more reliable patterns.

Beta Notice · July 2026

Bank Shot Buddy is in active development. The training methodology, physics foundation, and pattern library are real and ready to use at the table today. The interactive simulator is being built now. No numbers on this site have been fabricated — when real player data exists, you'll see it here.
