How to Masse the Cue Ball (Curve Shots)
The masse is the shot that makes people put down their drinks and watch. The cue ball leaves the tip, travels one direction, then bends around a blocking ball as if it changed its mind. It looks impossible, but it is just extreme spin doing what spin always does, curving the ball as friction with the cloth takes hold. It is also the shot most likely to get you yelled at by a room owner, so it pays to learn it correctly and practice it somewhere you are allowed to.
How the Curve Actually Works
When you strike down on the cue ball off-center, you give it two things at once: a direction of travel and a tilted axis of spin. At first the ball skids along the initial line. As cloth friction grabs the spinning surface, the ball begins to follow the spin, and the path bends. The steeper your cue and the farther from center you hit, the more the spin axis tilts and the harder the curve. Think of the tip contact like a clock face on top of the ball: hitting at 4 or 5 with a raised cue curves the ball to the right, hitting at 7 or 8 curves it left. Speed stretches the curve out; a softer hit lets it bend sooner.
Semi-Masse: The Curve You Will Actually Use
Most practical game situations call for a semi-masse, sometimes just called a curve shot. Elevate the cue 30 to 60 degrees, address the cue ball slightly off-center on the side you want it to bend toward, and stroke smoothly through the ball rather than stabbing at it. The cue ball will travel a foot or two on its initial line, then arc around the edge of a blocking ball to reach your target. Start by trying to bend the ball just a few inches over three feet of travel. That modest curve is enough to clear the edge of an obstructing ball and is far more controllable than a full hook. Keep your bridge hand planted firmly and your grip light; a tight grip at elevation is the fastest route to a miscue and a chewed-up piece of cloth.
Full Masse: Near-Vertical and Unforgiving
A full masse puts the cue at 70 to 90 degrees, almost straight down. The stroke comes from the shoulder and wrist, driving the tip down through the ball into the cloth. Done right, the cue ball can travel forward a short distance and then return, or hook sharply around a ball only inches away. The margin for error is tiny. A millimeter of contact difference changes the whole path, and grip pressure matters: keep the hand relaxed so the cue can rebound off the ball instead of pinning it into the slate. Full masse shots are rarely the percentage play in a real game. Learn them for the control they teach, not because you expect to need one on league night.
Why Table Owners Get Nervous
Every masse drives the cue ball down into the cloth and slate, and a mishit can do real damage. The common injuries are a crescent-shaped tear where an unchalked tip slid off the ball, a burn mark from the ball grinding into the cloth, and in bad cases a cracked ferrule or a ball dent in the slate backing. This is why many rooms post no-masse signs and why you should always ask before practicing curves on a table you do not own. Chalk thoroughly before every attempt, keep your tip well shaped, and lay a spare piece of cloth or a towel under the practice area when you are drilling repetitive full masse strokes at home.
A Safe Practice Progression
Start with the cue at about 30 degrees and a center-ball hit, just getting comfortable stroking downward without miscuing. Then move the tip a half-tip off center and watch for a gentle bend over four or five feet. Once that curve is repeatable, place an obstacle ball and practice bending around its edge to hit a target ball. Increase elevation only when the current angle feels boring. Fifteen minutes of curve practice a week is plenty, and the side benefit is real: you will finally understand why your normal shots drift off line whenever you use sidespin with even a slightly elevated cue. Curve practice makes that swerve a tool instead of a mystery.

Sturdy Hard-Tip Full Cue
Elevated and masse strokesA stiff, solidly built cue with a hard, well-shaped tip stands up to steep downward strokes far better than a whippy shaft with a soft tip, reducing miscues and ferrule stress.

Cloth care after practiceMasse practice grinds chalk into the cloth, so a proper table brush keeps the surface clean and helps you spot any burn marks before they get worse.

Is the masse legal in league play?
Under most standard rulesets the shot itself is legal, but many venues and some leagues ban it to protect their cloth. House rules override the rulebook here, so always ask before shooting one in a match.
Will masse shots ruin my cue?
Not if your equipment is sound and your tip is chalked. The risk comes from miscues, which jam the ferrule against the ball, and from thin-shafted cues flexing under steep strokes. A sturdy cue with a hard, fresh tip handles curve practice fine.
Why does my cue ball curve when I am not trying to masse?
Any time you use sidespin with your cue even slightly elevated, you create a small masse effect called swerve. It is why long shots with english drift off line, and it is the main practical reason to understand masse physics even if you never shoot the trick shot.
