Spin a slot from a major studio, and the result comes from a random number generator on that studio's server. Roll a provably fair dice game, and the result comes from seeds the player can check afterwards.
Both games look similar on screen, yet their results travel very different paths. One relies on certified software and audits, while the other relies on cryptography and, in some cases, a smart contract.
The origin of each result shapes what a player can verify, who controls the outcome and which protections apply.
Three Sources of a Casino Result

Provably fair systems let players confirm a round wasn't altered after the bet. Bitzo's guide to how provably fair verification works walks through the steps.
Studio Slots Rely on Certified Software
Major providers run their RNGs on their own servers. Testing labs such as GLI, eCOGRA, iTech Labs and BMM check that the output stays random and that payouts match the published return to player.
Players cannot verify a single studio spin themselves. Trust rests on the lab certificate, the provider's licence and the casino's choice of RTP build, since studios often offer several return settings for the same title.
Third-party games verify differently for that reason, as an explainer on why third-party games work this way describes.
Provably Fair Originals Rely on Cryptography
Provably fair games commit to a hashed server seed before the bet. After the round, the casino reveals the seed, and the player can recombine it with their own client seed and the nonce to reproduce the result.
This method proves the casino didn't change the outcome after seeing the bet. It doesn't prove the game's long-term return, which depends on the payout table the casino sets.
Fully On-Chain Games Go Further
Some Web3 casinos run games entirely through smart contracts. Randomness comes from an on-chain source such as a verifiable random function, and every bet and payout appears as a public transaction.
These games remove the casino's server from the result path. They also make every bet public and add smart contract risk if the code contains a flaw.
Licensed Lobbies Mix Both Types
Licensed crypto casinos usually offer far more studio slots than provably fair games. Certification requirements and provider agreements shape that balance, as a look at provably fair games in a licensed lobby explains.
Players who value self-verification can filter for provably fair titles, while those who want branded studio content accept the audit-based model.
Dexsport's Lobby Across Both Models
Dexsport marks 62 games as provably fair inside a library of 7,500-plus titles. Around 3,300 slots come from more than 45 studios, and roughly 870 live tables add the camera-based model.
Dexsport's provably fair section suits players who want to check rounds themselves, while its studio slots follow provider certification. Casino play counts twice toward its pre-withdrawal wagering rule.
Dexapp LTD holds the Anjouan licence behind Dexsport, whose terms allow ID requests whenever needed.
Conclusion
Studio slots draw results from certified RNGs on provider servers, checked by testing labs and licence audits. Provably fair originals combine server and client seeds that players can verify after each round.
Fully on-chain games move the result into a smart contract with on-chain randomness, making every bet public. Live tables rely on physical equipment and studio controls.
Dexsport combines 62 provably fair titles with around 3,300 studio slots and roughly 870 live tables. Match the game type to the kind of verification you value. Countries set their own casino rules, so confirm the local rules, play only after reaching legal age and remember that KYC or AML checks may apply.
