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 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.
