Playing it well
The house throw is locked in before you choose, so there is no pattern to fall into and nothing to outsmart. Rock is exactly as good as paper.
With only three outcomes it is an easy place to sanity-check the odds. Play a few hundred quick rounds and you should win roughly a third of them and end up near where you started.
Quick check. Read the tie rule first, then the win payout. Ties pushing with a 2.00× win is a zero edge. Ties pushing with 1.98× is a 1% edge. Ties losing with a 2.00× win would be a 33% house edge.
Fair odds are not a winning system. Taking the casino’s advantage away does not hand you one. The best any of these games does is break even over time, and a bad night can still take everything you brought. Decide what you are willing to lose before you open the game, not halfway through it.
What it pays
The numbers below are what actually lands in your balance, using a $10 bet as the example.
You win a third of the time, lose a third and tie a third. If a tie gives your stake back, a fair win has to pay double — anything less and the house is taking a cut.
So check two things before you play: what a win pays, and what happens on a tie. If ties count as a loss, a fair win would need to pay triple instead.
| Result | How often | A $10 bet returns |
|---|---|---|
| You win | 1 round in 3 | $20 |
| You tie | 1 in 3 | $10 back |
| You lose | 1 in 3 | Nothing |
FAQ
Check the game panel — this one rule changes the entire calculation. If ties return your stake, a fair win pays 2×. If ties count as losses, a fair win has to pay 3×. A game treating ties as losses while paying 2× would carry a 33% house edge.
