FAQ
What does Tanzanite Certified mean?
It means a casino has achieved all of the core pillars we believe are essential to a trustworthy casino. It is a real measure of the product, above and beyond a simple license.
Can a casino lose certification?
Yes. Certification can be withdrawn if the evidence changes or a casino no longer meets the standard.
How is provably fair assessed?
A majority of house games must be provably fair. Any game advertising provable fairness must be correct: players must be able to influence the result and get clear seed, event, and verification instructions for every relevant game.
How is proof of funds assessed?
When proof of funds is the remaining missing criterion, we compare the site maximum wins against funds linked to the casino. Hot wallet balances may count, but operators often need to verify exchange or cold wallet funds to cover the difference. Casinos can also ask for this check earlier, while other Tanzanite Standard criteria are still missing.
Is this a replacement for a license?
No. A license confirms registration with a regulator; Tanzanite measures the player-facing checks a license may not cover.
