Is Roobet Rigged? What “Provably Fair” Proves, and What It Doesn't

Short answer: for Roobet’s own games, Roobet publishes a way to check that each result was fixed before you bet. If the check passes, the site did not change that result after seeing your bet. That is all “provably fair” proves. The games still carry a house edge, Roobet’s fairness page doesn’t cover slots from other studios, and none of it tells you whether a withdrawal will be paid.

What provably fair proves

How Roobet says its games work

Roobet’s fairness page says: “Provably fair means you do not need to ‘trust’ us to be fair; it means you can prove our fairness.” It covers its own games: Roulette, Crash, Dice, Mines, Towers, Coinflip, Plinko, Mission Uncrossable, Keno, Blackjack, Slide, Limbo, Striker and Wheel. Slots and live dealer games from other studios are not on that list.

Roobet describes two methods.

Crash and Roulette (shared rounds). These use two ingredients: a server seed from Roobet and a client seed that is “the hash from a crypto block (like Bitcoin or Ethereum)”. Roobet hashes a server seed with SHA256, then hashes that, “until we have 2 million hashes”. Games are played backwards down the chain. Roobet says it commits to the hash of a crypto block “before that block is mined”, after creating all the server seed hashes, so “we could not control the outcome of each game”.

Dice, Mines, Plinko, Limbo and other single-player games. These use three ingredients:

• Server seed, provided by Roobet. You see its SHA256 hash when you start playing.
• Client seed, provided by you. You can change it before any bet.
• Nonce, a number that goes up by one with each bet.

When you verify, Roobet reveals the server seed, re-runs the three ingredients to regenerate your result, and resets your nonce and server seed. On its Dice tab, Roobet notes the game was moved to a newer engine, so Dice bets placed before and after that move use different verifiers.

How to verify a Roobet round yourself

For Dice, Mines, Plinko, Limbo and the other single-player games:

1. Before you play, note the hashed server seed and set your own client seed in the fairness settings.
2. Play your bets. Note the nonce of any bet you want to check.
3. Reveal the server seed. This also starts a new seed pair, so do it when you have finished with the current one.
4. Hash the revealed seed with SHA256 using any SHA256 tool. The result must equal the hash you were shown in step 1.
5. Use Roobet’s “Verify Results” tool (or your own code) with the server seed, client seed and nonce. The result it produces must match your bet history.

For Crash and Roulette, enter a game’s server seed in the verifier. It shows the server seeds and results for the previous 100 games. Each one should hash to the next in the chain.

If a hash doesn’t match, that is evidence worth keeping. Take screenshots and contact Roobet before anything else.

The house edge is still there

Provably fair proves the draw wasn’t changed. The payout table decides who wins over time. Roobet’s fairness page and its house games guide explain how each game works but do not state a house edge or RTP figure. We did not find one on either page, so we don’t quote one. Treat any Roobet house-edge figure you can’t trace back to Roobet itself with care.

One Crash point catches people out. Roobet’s Crash help article says rounds run in real time, and a cash-out sent too late because of lag “was not received in time”. Roobet says it automatically refunds bets hit by a site-wide or server-side issue. It says it can’t refund client-side connection problems, and suggests Autocashout. A lost cash-out from lag is not the result being rigged. It is also not something provably fair can check.

Roobet’s licence

Roobet’s terms also say a Cyprus company, Raw Entertainment Ltd, acts as a paying and operational agent. The Curaçao Gaming Authority’s register warns that its overviews “do not guarantee the current validity of the licenses”.

A Curaçao licence is not a licence in Canada or the US.

• US: Roobet’s restricted regions are Aruba, Australia, Bonaire, Cuba, Curaçao, Cyprus, Gibraltar, Haiti, Iran, Iraq, Malta, Myanmar, the Netherlands, Nicaragua, North Korea, Saba, Saint Maarten, Saint Martin, South Sudan, Statia, Syria, the United States, the United Kingdom, Yemen and Zimbabwe.
• Canada: Canada isn’t on that list. Roobet is not in iGaming Ontario’s directory or on Alberta’s list of registered sites (both checked October 10, 2026). So it is not regulated in either province. See Are offshore gambling sites legal in Canada?

What provably fair can’t protect: your withdrawal

Roobet’s terms let it hold up payouts in some cases:

• It can ask for any KYC documents and restrict deposits and withdrawals “until you have completed the identification process” (clause 4.9).
• Before a withdrawal it can do enhanced due diligence. If it suspects a breach, it may “delay or decline” withdrawals and may not explain why (clause 10.4).
• From the tenth fiat withdrawal in 30 days on, it charges a 2% fee on each one (clause 10.8).
• The terms are governed by Curaçao law. Complaints go to CS@roobet.com.

Canadian regulators can’t step in. iGaming Ontario says it “has no legal relationship with unregulated igaming Operators” (iGO). See Gambling withdrawal complaints in Canada.

If you need a break

Roobet’s help centre has a self-exclusion article. Provincial programs don’t reach it: Ontario’s BetGuard covers “all regulated igaming websites in Ontario” (iGO FAQs), and Roobet isn’t one of them. For free, confidential help, see Problem gambling help in Canada.
