Class II and Class III slots are distinguished by their mechanics and regulations. Class II slots, commonly in tribal casinos, operate like bingo machines with outcomes determined by a central server, where players compete for shared jackpots. In contrast, Class III slots, found in commercial casinos, use random number generators for independent outcomes, providing a traditional gaming experience with more diverse games. Class III is also governed by stricter regulations, influencing game play, payouts, and the overall casino environment for players.
