Gaming machine technical standards
See our gaming machine technical standards (categories A and B1) for the full details of the technical standards which this category of machine must comply with.
All gaming machines sited on casino premises must comply with our gaming machine technical standards.
Category B1, B2, B3 and B3A gaming machines must be tested by an independent test house to ensure they comply with the technical standards in full. Test houses are also sometimes referred to as test labs.
For categories A, B1, B2, B3, B3A, B4, C, D, server networked and downloadable, cashless payment, linked progressives and wireless networks refer to the gaming machine testing strategy.
Return to player (RTP)
B1 machines must display the 'theoretical target percentage return to player'. RTP is an average measured over a large number of games and will vary over a typical session due to normal game volatility.
The manufacturer will decide on the game RTP.
There is no minimum RTP requirement. However, the minimum average return must be displayed to the player for the game.
The value displayed must be verified either by the manufacturer or accredited test house for categories B1, B2, B3 and B3A.
