Provably fair tech at Roobet: NZ’s most trusted online game
Trust is one of the most important factors NZ players consider when choosing an online casino. Before placing a bet, you want to be sure that games are operating fairly, through a transparent gaming environment.
This is especially important for online casinos, since you can’t physically see how rounds are managed like in live tables. Instead, you have to rely on systems like a random number generator (RNG) and just trust that every result is being generated fairly and reliably.
The importance of trust and reliability is something that Roobet is aware of. One of the features Roobet uses to establish the trust that NZ players need is provably fair technology. Whether you’re playing Mission Uncrossable or any of Roobet’s other original titles, you can play with full confidence that every round is fair.
What does provably fair mean?
Provably fair means you can check any game result yourself once a round ends. The platform shares the exact data used to decide the outcome, so you know everything is completely transparent.
The system uses three main pieces of data: a server seed from the site, a client seed from your device, and a nonce. These three values mix to create the final result.
To show that the game is honest, Roobet turns the server seed into a secure code called a hash and displays it before the round begins. Having this code upfront proves that the game’s outcome was already locked in before you placed your bet.
What games use provably fair tech at Roobet?
All of Roobet’s original titles make use of provably fair tech. The ‘Provably Fair’ page even outlines exactly how each game generates results and how you can use the tools to verify the outcome.
Even though every original title has different mechanics, you can play all of them without worrying about results being changed mid-round. Roobet’s commitment to transparency and to providing the best possible casino experience shines through in its use of provably fair tech in its original game designs.
How does it work?

While the process can seem complex, the process that provably fair tech works through is actually fairly simple. Secure values are combined to generate the game result, and those values can then be checked to confirm the fairness of the outcome.
| Factor | Purpose |
| Server Seed | A value generated by the platform before the round begins. |
| Client Seed | Data provided by the player’s platform. |
| Nonce | A number that changes between rounds to ensure unique outcomes. |
| Hash | A secure data string that can’t be changed once generated |
| Final Result | The outcome is generated from the combined inputs. |
Before the game starts, the site generates a server seed and shows it to you as a secure code, or hash. This code serves as an unchangeable reference point that you will use later to double-check the outcome.
Next, your client seed mixes with the server seed. The game automatically runs these numbers through a calculation to determine the final result of the round.
Once the game ends, the site reveals the original, unscrambled server seed. You can take that seed, plug it into the tools on Roobet’s ‘Provably Fair’ page, and turn it into a hash yourself.
If your new hash matches the one you saw before the round started, you know the game used the exact data it promised. This simple check proves that the platform did not alter your results during play.
