What labs do

Testing labs audit a game's RNG, verify that payouts match the stated rules, and check that systems behave correctly. Operators use their certificates to show games are fair.

The main labs

Well-known independent testers include eCOGRA, iTech Labs, GLI (Gaming Laboratories International) and BMM Testlabs. A game or operator that has passed their tests can display a seal.

What a seal means. It signals independent verification — but check the seal is genuine and current, ideally linking to the lab's own site.

What a certificate covers

Certificates can cover RNG randomness, return information accuracy, and responsible-gambling and dispute processes. See eCOGRA and fairness testing.

Lab vs licence vs provably fair

Three things support trust: a licence (the operator), lab testing (the games), and provably fair (player-verifiable results). Strong operators have more than one.
