Editing Slot machine (section)

====Category B====
Category B games are divided into subcategories. The differences between B1, B3 and B4 games are mainly the stake and prizes as defined in the above table. Category B2 games – [[Fixed odds betting terminal]]s (FOBTs) – have quite different stake and prize rules: FOBTs are mainly found in licensed [[betting shop]]s, or bookmakers, usually in the form of electronic [[roulette]].

The games are based on a [[random number generation|random number generator]]; thus each game's probability of getting the jackpot is independent of any other game: probabilities are all equal. If a [[pseudorandom number generator]] is used instead of a truly random one, probabilities are not independent since each number is determined at least in part by the one generated before it.
