Adults only

The Edu Casino is for adults (18+). It uses fictional chips only — no real money, nothing to buy, nothing to win.

House Edge Roulette

A practice roulette table with 100 fictional chips. Each round the table offers a bet: work out its win chance or expected value, then bet or sit out. An EV panel tracks the expected result next to the real one, and a 1,000-spin simulation shows the drift.

How to play

Pick a wheel. Single zero (37 pockets, 2.70% edge) or double zero (38 pockets, 5.26% edge).
Answer. Each round, say the win chance or the expected value of the bet on offer.
Bet or sit out. Bet the fictional chips or just watch the spin. Sitting out never costs points.
Score. 100 per right answer, plus your expected chips: decisions count, luck doesn't.

Quick tips

Count the pockets. Red wins 18 of 37 pockets on a single-zero wheel, not 18 of 36.
Every bet has the same edge. On these wheels every bet keeps 2.70% (single zero) or 5.26% (double zero) of each chip on average.
Expected value is a long-run average. EV = chance of winning × win − chance of losing × stake. One spin can go either way.
Sitting out is worth zero. Not betting is the only choice with no expected loss, and it never costs points here.
Run the simulation. 1,000 spins show luck shrinking and the edge taking over.
