The Secret World of Casino Game Testing and Certification

Casino games like slots, roulette, and blackjack seem simple on the surface for a player. Put in money, press a button or throw the dice and watch the results unfold. However, behind the scenes, is an intricate world of mathematics, technology, regulations, and auditing governing these games to ensure fairness and randomness for players. This article will provide an inside look into the secretive industry of casino game testing and certification.

The Need for Testing and Certification

Casino games rely heavily on elements of chance and randomness to ensure each outcome is independent of the last. The sequence of numbers from a roulette wheel spin or the arrangement of symbols in a slot game must be completely random and free of bias. Even the slightest pattern or predictability can be exploited and compromise the integrity of gameplay.

Additionally, casinos like Kansino are for-profit enterprises with a statistical edge built into most games. While the inclusion of a house edge is necessary and disclosed to players, casinos could unfairly tweak the odds in their favor.

For these reasons, regulatory bodies mandate that all casino games undergo rigorous inspection, testing and certification by accredited third-party labs before deployment in a live casino. Jurisdictions like the UK, Gibraltar and Malta require compliance and certification to operate legally.

The Testing and Certification Process

Game testing involves both mathematical analysis and extensive simulations of gameplay. Test labs thoroughly examine the random number generator (RNG) and source code powering the game for bias. The RNG must produce output that is statistically random, non-predictable and passes various statistical tests. Table 1 shows some common statistical tests used.

Common Statistical Tests for Random Number Generators

Chi-SquaredDetermines how likely an observed distribution matches a theoretical distribution
RunsChecks if too many patterns/runs exist in sequence
PokerSpecial test for card/table games to determine fair card distribution
PermutationAnalyzes distribution of all possible outcomes

The game mathematics and payouts are also reviewed in-depth during testing. This includes verifying the stated pay table and odds match the actual long-term payback percentage accounted for in the code.

In addition to mathematics, labs will simulate billions of game rounds. This allows them to verify in practice that the stated odds are realized, and no unintended patterns emerge.

If issues are uncovered in testing, the lab reports them to the game creator for resolution before certification can proceed.

Obtaining Certification

Upon successfully completing testing without major issues, labs can issue certification for the game. Common certifications include:

  • UKGC: Issued by labs accredited by the UK Gambling Commission,
  • GLI-19: Gaming Laboratories International standard covering integrity,
  • RNG: Explicit certification of RNG fairness,

Certification confirms the game meets requirements for randomness, fairness and lack of predictability. It also signals compliance with major gaming jurisdiction regulations.

The presence of certification marks on a game interface lends further credibility and transparency to players. It communicates rigorous external testing was completed to verify game integrity.

Ongoing Monitoring

The process does not end after the initial certification. Accredited labs have ongoing monitoring programs to regularly retest live games. This ensures the integrity has not degraded over time as the game accumulates more plays. Monitoring may uncover issues like a weakening RNG or a change to the game mathematics by the operator.

Labs will revoke certification for non-compliance until the operator corrects the issue. Continuous oversight maintains player confidence in fair gameplay.

Inside Look at a Secretive Process

Far more than just lights, sounds and artwork, casino games rely on complex mathematics and technology operating in line with regulations. The extensive testing and certification process, while hidden from players, works constantly in the background to uphold game randomness and fairness. So the next time you press spin or bet it all on black, you can have confidence the game was rigorously vetted to provide a fair shot.
