A slingshot is a hand-held Y-shaped frame with a rubber band, and it fires by releasing the elastic you stretched. A catapult is a machine that throws something using stored mechanical energy, usually from twisted rope and sinew or from a falling counterweight. The confusion is mostly a language problem: in British English, “catapult” is the normal word for the hand-held toy that Americans call a slingshot.
For games, the practical difference is what your finger does. A slingshot asks you to set an angle and a stretch. A catapult asks you to time a release.
How a slingshot stores energy #
Pull the pouch back and the rubber stretches. Stretched rubber stores elastic potential energy, and letting go converts most of it into the projectile’s speed. Two things decide where the shot lands: how far you pulled, which sets the launch speed, and which way you pulled, which sets the angle.
That’s why nearly every slingshot game caps the stretch. Once the band is at its limit, extra pull adds no speed, and your only remaining control is direction. Locking the power at maximum and changing only the angle is the single biggest improvement most players can make, and it’s the core of our slingshot aiming technique guide.
The word itself is younger than you’d think. The Online Etymology Dictionary records slingshot from 1849, formed from “sling” and “shot,” and defines it as a “hand-catapult” — which is exactly the ambiguity this article is about.
How a catapult stores energy #
Catapults are siege engines, and they come in families depending on where the energy comes from.
| Machine | Energy source | Notes |
|---|---|---|
| Ballista | Torsion in twisted rope or sinew | Works like a large mounted crossbow |
| Mangonel | Torsion, driving a single arm | The arm swings up against a stop |
| Trebuchet | A falling counterweight | Medieval, roughly the 12th to 14th centuries |
The trebuchet is the one most games copy, because it’s the most visual. A counterweight of stones drops, the long arm swings, and the sling on the end whips the projectile forward. Nothing is stretched and nothing is twisted; the whole thing runs on gravity acting on a heavy box.
The word “catapult” is much older than “slingshot.” Etymonline dates catapult to the 1570s, from the Greek katapeltēs, built from a word meaning “against” (as in against walls) and a root meaning to toss or hurl. In Roman use it named “a Roman military engine for throwing huge darts.” By 1927 it had also come to mean the device that launches aircraft from a carrier deck.
Side by side #
| Slingshot | Catapult | |
|---|---|---|
| Size | Hand-held | A machine, often siege-sized |
| Stores energy in | Stretched elastic | Twisted fibre or a raised counterweight |
| You control | Angle and stretch | Usually the release timing, sometimes the counterweight |
| Reload | Instant | Slow, often needing a crew |
| Typical projectile | A stone, a ball bearing, an angry bird | A boulder, a dart, a fire pot |
| Accuracy | Good at short range, in a trained hand | Better suited to an area than a point |
Why British and American English disagree #
In the UK, the Y-shaped toy is a catapult. In the US, it’s a slingshot. Neither is wrong, and the overlap is old: the 1849 definition of “slingshot” literally uses “hand-catapult” to explain it.
This trips people up when searching for games. A British player looking for “catapult games” often wants Angry Birds, which is a slingshot game, while an American searching the same phrase usually wants trebuchets and castles. Our two lists are split the way the machines actually work: best slingshot games and best catapult games.
How games use each one #
Slingshot games give you a drag-and-release control that maps directly onto the real thing. Angry Birds is the famous one. Kitty Kaboom, our cats-versus-robots game, works the same way: you drag back from a wooden fork, a line of white dots previews the arc, and you release to fire a cat at a tower of cardboard, wood, glass, brick or metal. Because the pull is capped, every full-power shot leaves at the same speed, so the angle is the only variable you’re really learning. Six of the seven cats then add a mid-flight tap power, which is a thing no real slingshot does.
Catapult games usually turn the launch into a timing problem. In a trebuchet game you watch the arm swing and tap at the right moment, which feels less like aiming and more like rhythm. Crush the Castle, which reached the App Store in September 2009, is the template.
Cannon games get grouped in with both, though a cannon is neither: it uses expanding gas, not stored mechanical energy. If a game asks you to set an angle and a power bar, it plays like a slingshot whatever the art shows.
Does the physics differ once it’s in the air? #
No. Once the projectile leaves the machine, only two things matter: how fast it’s going and in what direction. Gravity bends the path into the same arc regardless of what threw it. That’s why aiming skill transfers between a slingshot game, a trebuchet game and a cannon game, and why 45 degrees is the farthest-reaching angle on level ground in all of them. We work through that in what launch angle goes the farthest.
The machine only decides the starting conditions and how much control you have over them. A slingshot gives you fine control over both speed and angle. A trebuchet gives you a fixed throw and one moment to release.
Frequently asked questions #
Is a slingshot a type of catapult? #
In the loose sense, yes: both store energy and release it to throw something. In technical use, catapults are siege engines powered by torsion or a counterweight, while a slingshot is a hand-held elastic launcher. British English treats the hand-held version as a catapult too.
Which is more powerful, a slingshot or a catapult? #
A catapult, by a wide margin. Siege catapults threw stones weighing tens of kilograms at walls. A slingshot throws something you can hold between two fingers.
What is the difference between a trebuchet and a catapult? #
A trebuchet is a catapult that uses a falling counterweight instead of twisted rope. Torsion machines like the mangonel and ballista store energy by twisting fibre; the trebuchet stores it by lifting a heavy weight.
Do Angry Birds and Kitty Kaboom use slingshots or catapults? #
Both use slingshots. You stretch elastic and release it, and the games show a Y-shaped fork with bands. Crush the Castle is the well-known trebuchet game.
Why do British people call a slingshot a catapult? #
The words overlapped from the start. “Catapult” arrived in English in the 1570s as a name for throwing engines and later stretched to cover the hand-held toy in British usage, while American English adopted “slingshot” from 1849. Both names describe the same piece of rubber on a forked stick.
