Rock, Paper, Scissors

Win big with the timeless classic: Rock, Paper, Scissors!

In RPS players compete against the house by choosing one of three options: rock, paper, or scissors. The rules of the game are straightforward: rock beats scissors, scissors beats paper, and paper beats rock. If the player and the computer both choose the same option, the game is a draw. The outcome is determined by the VRF, and the player either wins or loses depending on the result.
Following table shows the payout multipliers for different cases.

Each of the three outcomes is equally likely. So, here's how the expected value for a 1$ is calculated:
Expected Value=13×0.96+13×(−0.02)+13×(−1)=−0.02.\text{Expected Value} = \frac{1}{3}\times 0.96  +\frac{1}{3}\times (-0.02)+ \frac{1}{3}\times (-1)=-0.02.Expected Value=31​×0.96+31​×(−0.02)+31​×(−1)=−0.02.
Therefore, the house edge of RPS is 2%.
