Gaming machine technical standards
See our gaming machine technical standards (categories B3 and B4) for 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 B4, C, and D gaming machines can be tested via an independent test house or via the manufacturers own processes under strict controls. 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)
B4 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.
