You can play rock paper scissors online for free right now on our play page: pick a throw against the computer, or play a real person, with no download and no account needed to start. The rest of this page explains what to look for in any RPS site or app, and how to actually win once you are there.
This used to be the "RPS Arcade" page. The arcade is gone and the play page replaced it, so everything here points to what exists today.

What makes a good online RPS game
I have played a lot of bad RPS sites. The good ones share a few things:
| What to check | Why it matters |
|---|---|
| Throws are locked in simultaneously | If one side can see the other's throw first, the game is broken |
| The computer's play is honest | A bot that secretly reads your click can win every round. A fair one commits before you do |
| You can see your history | Reviewing your last ten throws is the fastest way to spot your own habits |
| Ties are handled clearly | Real rules replay ties; some sites quietly count them, which skews records |
| No pay-to-win | Nothing about RPS should be purchasable. Cosmetics are fine; better odds are not |
| Plays in a browser | Apps are fine, but a site you can open from a link is easier to share with a friend |
A fair game against a computer is a real test of how random you are. A computer opponent that plays truly at random will win, lose and tie about a third of the time each against anyone, forever. A computer that tries to predict you can beat you if you are predictable, which most of us are.
Other places people play RPS online
A few kinds of places are worth knowing about:
- Chat and messaging bots. Many chat platforms and community servers have simple RPS commands. They are fine for settling a quick argument but usually keep no stats.
- Mobile app stores. Search either store and you will find dozens of RPS apps. Quality varies a lot, and many are thin wrappers for ads, so check the table above before you settle on one.
- Programming competitions. If you would rather write a bot than play by hand, Kaggle ran a well-known Rock, Paper, Scissors simulation competition from November 2020 to February 2021. Bots played 1,000-round matches against each other, and more than 1,600 teams entered. The competition is closed, but the public notebooks and write-ups are still a great education in pattern detection.
I am deliberately not listing specific third-party apps by name here. Apps come and go, and a list of dead links helps nobody.
How to win at online RPS
Online play is different from playing face to face. You cannot read hands or body language, so everything comes down to patterns in the throws themselves.
Against the computer
The State of RPS report describes WRPSA's dated throw frequencies and sample limits. Those observations concern players, not a promise about what the computer will choose. Against a machine, review your own completed throws and avoid becoming predictable.
Against people
Real opponents have habits, and there is decent research on what those habits are. In a 2014 Zhejiang University study by Wang, Xu and Zhou, 360 students played 300 rounds each, and winners tended to stick with their winning throw while losers shifted in a predictable direction.
The State of RPS report records a different after-win tendency from the laboratory study. It defines an upgrade as the throw that beats the player's own previous throw. Its sample is mostly computer play, so use these observations as hypotheses to test against a real opponent:
- Open with paper. Rock is the most common first throw.
- Watch what they do after a win. If they tend to stay, throw what beats their last throw. If they tend to move up (as our players did), throw what beats the throw that beats it.
- Watch what they do after a loss. If they tend to upgrade, expect the throw that beats their own previous throw.
- Change your own pattern every few rounds. A human opponent is watching you, too.
The full version is in our strategy guide, and if you are new, how to play covers the basics and the official rules cover ties and match formats.
Want more variety?
If three throws feel limited, try Rock Paper Scissors Lizard Spock, the five-throw version created by Sam Kass and Karen Bryla and made famous by The Big Bang Theory. It cuts down on ties. Our variations page lists other versions from around the world.
