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.

  • 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.
  • Therefore, the house edge of RPS is 2%.
