Fairness & RNG
Every round on Arcade Spin is decided by a pseudo-random number generator (PRNG) that runs entirely inside the browser — never on a remote server.
Anatomy of a spin
- You tap "Spin". The browser calls
Math.random(). - The returned floating-point value is mapped to one of the 37 pockets (0 through 36).
- The wheel animates and lands on that pocket.
- Any matching bets are credited to the virtual balance automatically.
No house tilt
Because the result is computed locally and paid in coins with zero monetary worth, we have no incentive — and no mechanism — to bias the wheel. There is no server-side adjustment based on the bet stack, balance, or history.
A note on the maths
European roulette uses one zero pocket. Even-money bets such as Red, Black, Even, or Odd lose when the ball settles on 0, which gives the house a long-run edge of roughly 2.7% in any paid version of the game. Arcade Spin uses the same wheel layout, so the same long-run statistics apply — only here, no money rides on the outcome.
See for yourself
Open the browser's developer tools, switch to the Network tab, and watch a few spins. You will not see any request leaving the machine to determine the outcome. The whole game lives client-side.
