Four short browser demos covering the core mechanics you'll find at crypto casinos — 3-reel slots, Over/Under 7 dice, Hi-Lo cards, and pick-a-box multipliers. Try the probability models behind real titles at Winz, Stake, and BC.Game before you ever sign up. Virtual credits only — no deposits, no withdrawals. 18+.
3 reels, 1 payline, 6 symbols. Match any two for 3×, match all three for 10×. No wilds, no scatters — pure classic-slot odds.
Launch demo →Call Over 7 or Under 7 on two dice. Hit pays 2×. A total of exactly 7 pushes (stake returned). 15 wins, 15 losses, 6 pushes out of 36 outcomes.
Launch demo →One card shows face up. Call whether the next card is higher or lower. Same rank pushes, correct call pays 2×. Read the probability before you commit each round.
Launch demo →Pick one of six closed boxes. You'll land on 0×, 1×, 2×, 5×, 10×, or 50× with uniform probability — a teaching model for real pick-a-box bonus rounds.
Launch demo →Crypto casinos sell big numbers — 150+ supported coins, $20,000 welcome packages. Knowing the actual hit frequency of a 3-reel slot or the real shape of the Over/Under 7 distribution is the only way to judge whether those bonuses are worth the wagering requirements. These demos live entirely in your browser; credits persist in localStorage. Every demo maps 1:1 to a mechanic at the crypto casinos we cover, so you can test the math before you use a welcome bonus.
