// demo mechanics, explained honestly
Crypto trading simulators, explained — before you risk anything real.
Crash, dice, and roulette are the three most common "trading-style" demo mechanics you'll find online. We break down how each one actually works, what it can and can't teach you, and why playing a demo round on fixed odds is a completely different thing from trading a real, unpredictable market.

Pick a mechanic
Crash
A multiplier climbs from 1.00x until it crashes at a random point. Cash out before it does, or lose the round.
Read the breakdown →Dice
Pick a target number and a direction. A fair-odds payout is calculated from your exact win chance.
Read the breakdown →Roulette
The oldest fixed-odds mechanic there is — bet on where a random spin lands, get paid by the odds.
Read the breakdown →Crash vs. Dice vs. Roulette, side by side
| Mechanic | Core decision | How the odds work | Main risk lesson |
|---|---|---|---|
| Crash | When to cash out while a multiplier is rising | Crash point fixed before the round starts; the climb is just an animation | Pre-committing to an exit rule and actually sticking to it |
| Dice | Pick a target number and a direction (under/over) | Payout = house-edge-adjusted inverse of your exact win probability | Probability vs. payout size is a direct trade-off, not a hunch |
| Roulette | Which number(s) or spread to bet on | Fixed payout table per bet type; same house edge at every spread | Concentrated vs. diversified risk, and why "due" numbers aren't real |
Why "demo" doesn't mean "practice for the real thing"
Every demo simulator on this site runs on code with fixed, known odds — a multiplier curve, a random-number roll, a wheel with a set payout table. The real crypto market has none of that. Prices move on order flow, liquidity, news, and other traders' decisions, not on a program deciding when to "crash" or where a wheel will "land."
That means the emotional experience of a demo round — the temptation to wait "one more second," the rush of a win, the urge to chase a loss — can be a genuinely useful thing to notice about yourself. What a demo round can't do is teach you to predict a real market, because a real market isn't running on the same code.
Read a breakdown, watch how a round plays out, try a demo round on play credits, and decide for yourself whether risking real money — in gambling, trading, or investing — is something you actually want to do. That decision is yours, not ours, and it deserves more than a five-minute impulse.
FAQ
Are these games actually trading simulators?
They simulate some surface-level trading behaviors — picking an exit point, sizing a bet, reading odds — but the underlying mechanic is a fixed-odds game, not a market. Think of them as a way to feel out your own risk instincts, not as trading practice.
Is this gambling?
The mechanics themselves — crash, dice, roulette — are classic gambling game formats. Played for real money, that's exactly what they are. This site covers the mechanics and demo versions only; whether and how you engage with any real platform running these games is entirely your own decision to make, at 18+.
Do I need real money to read these pages or try a demo?
No. Every page here covers the free demo mechanic, on play credits only.
