What each game is, in one minute
Crash is a real-time multiplier game: the line climbs from 1.00× until it randomly “crashes.” You must cash out before the crash to lock your multiplier. Popular titles range from crypto-native bustabit to studio games like Aviator by Spribe.
Dice is the simplest crypto original: you pick a win chance (for example, 50%) and the game rolls a number. If the roll is in your target range you win at a fixed multiplier; otherwise you lose. Dice on established sites is typically provably fair and often runs with a small built-in house edge.
Odds, RTP, and house edge compared
Crash RTP varies by title. Aviator by Spribe lists a 97% RTP (≈3% house edge), while bustabit—the classic crypto crash—states a 1% house edge (≈99% RTP). This means two crash games can feel identical but return different long-run percentages. Always check the game’s info page.
Dice on leading crypto sites commonly runs at a 1% house edge. For instance, Bustadice’s FAQ states “The house edge is 1%.” Community explanations for Stake’s dice show the same 1% edge in the payout math at common targets (e.g., 50% chance pays 1.98× instead of 2.00×).
RTP is a long-run average, not a short-session promise, and volatility determines how bumpy the ride feels. Industry explainers stress that RTP and volatility are separate: high RTP doesn’t mean frequent wins, and fast games like crash can publish RTP while still swinging hard.
Volatility and session feel
Crash outcomes follow a heavy-tailed distribution: many low multipliers, few very large ones. At the same RTP, lowering your auto-cashout target increases your hit rate but reduces average win size; stretching for big multipliers means rarer wins and more variance. Media guides and explainers highlight that crash’s appeal is precisely this trade-off between risk and reward.
Dice is steadier. Because you choose the win chance and the multiplier is fixed by that choice, variance is easier to tune. The house edge remains the same across settings, so changing your target mainly reshapes volatility, not expectation. Community walkthroughs illustrate the 50%→1.98× example and similar settings.
Provably fair: how both games prove fairness
Crash (bustabit) publishes its house edge and runs public “seeding events” that generate long hash chains in advance; players and third parties can verify that results were predetermined and not influenced by live bets. The help center explicitly states the house edge is 1% and that the game proves advertised odds.
Dice implementations on major platforms use client seed + server seed + nonce combined via HMAC-SHA256 to derive each roll, then reveal the now-expired server seed so you can recompute every result. Stake’s provably fair page documents this input set and HMAC-SHA256 process.
On-chain games may instead use a verifiable randomness oracle such as Chainlink VRF, which returns a random value plus a cryptographic proof that smart contracts verify on-chain before using it.
In regulated markets, provably fair complements—not replaces—testing and oversight. The UK Gambling Commission mandates ongoing compliance and even live RTP monitoring for remote games.
Example bet math you can verify
Crash at 99% RTP (1% house edge)
Many crash formulas imply that the chance of reaching or exceeding a target multiplier m is roughly (RTP)/m. With a 1% house edge (RTP 99%):
Chance to hit 2.00× ≈ 0.99 / 2 = 49.5%
Chance to hit 10× ≈ 0.99 / 10 = 9.9%
This aligns with community math tables used to illustrate bustabit-style games. Always consult the game’s own documentation for the exact mapping.
Dice at 1% house edge
If you choose a 50% win chance, the fair payout would be 2.00×, but with a 1% house edge it pays 1.98×. Community explanations show the calculation: house edge = (fair payout − actual payout) / fair payout = (2 − 1.98) / 2 = 1%.
Bankroll and risk management tips
Pick a small base unit (for example, ~1/50 of your session bankroll) to survive normal swings. Use auto-cashout in crash to control variance, and avoid chasing losses with aggressive progressions: they change variance, not long-term expectation. Because RTP is long-run and variance is high in both games—especially crash—pre-set loss and time limits are essential.
Safety, licensing, and crypto payment notes
Fair algorithms don’t replace consumer protections. If you’re in a regulated market, verify licensing and testing; the UK’s strategy includes live RTP monitoring and approved test houses.
Crypto deposits are typically irreversible once confirmed, so test with a small amount and double-check networks/addresses before sending.
Which should you play?
If you value steadier sessions you can dial in, dice with a 1% edge is the more predictable choice. If you want real-time sweat and are comfortable with swings, crash offers a thrilling variance profile—but its RTP varies by title, from 99% at bustabit to about 97% on Aviator, so the specific game you pick matters.
FAQs
Is crash always worse than dice?
No. It depends on the title. A 1%-edge crash game like bustabit has similar long-run odds to 1% dice, while a 3%-edge crash game like Aviator is mathematically worse—though many players still prefer its format.
How do I know my rolls or crash points are fair?
Look for a provably fair page that shows server seed (hashed), your client seed, and the nonce. After the seed is revealed you should be able to recompute any past round. Stake’s implementation notes HMAC-SHA256 with those inputs; bustabit publishes seeding events and documents the 1% edge.
Does RTP tell me how often I’ll win?
No. RTP is a long-run percentage return; volatility and your targets control how streaky outcomes feel. This distinction is emphasized in responsible-gaming explainers and media guides.
