Crash on Roobet, and an honest RTP gap.
Roobet runs its own in-house Crash on the same climbing-multiplier mechanic as the Crash calculator. Its exact RTP is where things get less clear-cut than most platforms — worth reading before you assume a number.
Sources disagree, so we're not picking a side.
Cited figures for Roobet's Crash RTP range from around 96–97% (a 3–4% edge, already meaningfully higher than the crypto-standard 1%) to notably lower figures from independent analyses claiming a much bigger edge based on code inspection and player-observed outcomes. We haven't independently verified either end of that range, and the lower-RTP claims specifically come from unverified third-party sources, not Roobet's own published documentation.
This calculator and every number on this page use the site-wide 99% RTP convention shared with Stake and BC.Game, purely for consistency across the tools on this site. If you're betting real money on Roobet specifically, treat that as a directional estimate, not Roobet's confirmed figure — check Roobet's own published fairness documentation, and be aware that third-party estimates for this platform vary more than most.
Same formula, a meaningfully worse number.
Whatever Roobet's actual RTP is, the win-chance shape doesn't change — it's still RTP ÷ target. What changes is how much smaller your win chance gets at any given target, and how much more the house keeps in the long run.
A 2-percentage-point RTP gap moves the 2× win chance by exactly 1 percentage point — small-looking per bet, but it compounds every round you play.
A verification tool exists — use it.
Roobet publishes a seed-checking sandbox that lets you verify server/client hash values against your own bet history — the same seed-pair model used industry-wide. Reviews note the tool is less approachable than Stake's or BC.Game's equivalents, so expect to spend more effort actually running the check yourself.
Seed pair, published upfront
A hashed server seed is shown before you bet, committing to the round's crash point before you know it.
A sandbox tool for verification
Roobet's fairness sandbox lets you re-run the hash calculation against your own bet history.
Independent of the RTP question
Provably fair proves a round wasn't tampered with — it says nothing about which RTP constant is baked into the payout table itself.
Questions specific to Roobet's version.
What is Roobet's actual Crash RTP?
We don't know for certain, and neither does most public reporting — cited figures range from around 96–97% to notably lower estimates from unverified third-party analysis. We're deliberately not asserting a specific number here; check Roobet's own fairness documentation if you need a confirmed figure.
Does this calculator model Roobet's exact numbers?
No — it uses the 99% convention shared across this site for consistency. Given the genuine uncertainty around Roobet's real RTP, treat every number on this page as directional for Roobet specifically, not a confirmed match.
How would the win-chance formula work if Roobet's RTP is lower than 99%?
The formula shape never changes — only the RTP value plugged into it does.
The formula
- Win chance for target m is RTP ÷ m, whatever Roobet's actual RTP constant turns out to be.
- A lower RTP shrinks the win chance at every target proportionally — a 2-point RTP drop costs roughly 2% of your win chance at any given target.
- The edge grows correspondingly: (RTP − 1) × bet gets more negative as RTP falls.
Comparison at 2× target
- At 99% (this site's convention): 49.50% win chance
- At a cited 97%: 48.50% win chance
Is Roobet's Crash provably fair?
Roobet publishes a seed-checking sandbox for independent verification, the same seed-pair model used across the industry — though it's reportedly less user-friendly than Stake's or BC.Game's equivalent tools. Provably fair verification confirms a round wasn't tampered with; it doesn't by itself confirm which RTP figure is accurate.
Why does this guide hedge more than the Stake or BC.Game ones?
Because the underlying facts are genuinely less settled for Roobet. Stake and BC.Game both cite a consistent ~1% edge across multiple sources; Roobet's reporting is more scattered, including some claims we can't verify. We'd rather show that honestly than round it off to a clean number that isn't actually confirmed.
Is there a best cash-out target on Roobet?
No — whatever Roobet's real RTP turns out to be, every target shares the same edge under that RTP. The general trade-off between target size and win frequency is broken down on the Crash strategy page.
Do "predictor" tools or timing patterns work on Roobet's Crash?
No, for the same reason they don't work anywhere else: the crash point is drawn before the round starts, from data a browser tool has no access to. This applies regardless of which RTP figure turns out to be accurate for Roobet specifically — the fairness mechanism and the impossibility of prediction are separate questions from the RTP dispute above.
