Independent testing that a game's random number generator is genuinely unpredictable and statistically fair, carried out by an accredited lab such as GLI or eCOGRA.
No regulated market will license a game without it, and operators cannot accept content that lacks a current certificate — it is a gate, not a quality badge.
We build platforms that record which certified build of a game is live and when it changed, because an uncertified version reaching players is a compliance incident, not a bug.
