Rock, Paper, Scissors
Settle it without both of you throwing at the same time and arguing about it.
Playing against someone who cannot read you
Rock paper scissors is not really a game of chance between people. It is a game of reading habits, and humans have plenty: players throw rock first more often than the other two, and a player who just lost tends to switch to whatever would have beaten them.
That is what makes the game beatable by anyone paying attention - and why a wheel is a genuinely different opponent. It has no pattern to spot, no tell, and no memory of the last round.
Settling something with one throw
The most common use is not a game at all. Two people, one thing neither wants to do, and rock paper scissors as the accepted way to decide it - the wheel simply removes the argument about whether someone threw late.
Simultaneity is the part that breaks down in person, especially over video where the lag is real. A spin everyone watches has no such problem: the result appears at the same instant for everybody.
Variants worth adding
The three-throw version is one option among many, and the wheel takes any of them because the list is just text.
Beyond rock, paper, scissors
- Rock Paper Scissors Lizard Spock. Five throws, ten outcomes, and a much lower chance of a draw. Add the two extra entries and the wheel handles it.
- Best of three, tracked. Turn on Count and the Results tab keeps the running score without anyone having to remember it.
- Weighted handicap. Give one throw more of the wheel if you are playing against someone who needs a head start. Visible on the rim, so nobody can claim they did not know.
Is the wheel a fair opponent?
Fairer than a person, in the specific sense that it plays each throw with exactly equal probability and cannot be read. Every spin draws from your browser's cryptographic random number generator, and the result is chosen before the wheel starts turning.
Against a human opponent this makes the wheel unbeatable in the long run - not because it wins, but because it cannot be exploited. Over many rounds you will land on a third each way, which is exactly what playing an unreadable opponent looks like.

Questions
Rock Paper Scissors Wheel FAQ
Can I play Rock Paper Scissors Lizard Spock?
Yes. Add Lizard and Spock to the entries and the wheel rebuilds with five throws. The wheel picks a throw; the rules of who beats whom are still yours to apply.
Can it keep score across rounds?
Yes. Turn on Count in Settings and the Results tab tracks how many times each throw has come up, which doubles as a running score for best-of series.
Is the wheel actually unpredictable?
Yes. Each spin uses crypto.getRandomValues() rather than the ordinary Math.random(), and the result is drawn before the animation runs. There is no pattern to read, which is the one advantage it has over a human opponent.
Why use a wheel instead of throwing by hand?
Because simultaneity breaks down in person and badly over video, where lag makes late throws hard to rule out. A spin everyone watches resolves at the same instant for all of them.
Can I give one throw better odds?
Yes, using weights. A throw weighted 2 against throws weighted 1 takes twice the wheel. The split is visible on the rim, so a handicap is never hidden.
