Class II and Class III Slot Machines
Slot machines in most countries, specifically the U.S., are either Class II or Class III. Class II slots are well-liked in land-based Native American tribal casinos. Class III slot machines, however, are usually used in commercial casino venues in large cities like Atlantic City.
Class III slot outcomes are strictly a function of chance and probability, and every spin is a function of randomness. Class II slots are different in the sense of functioning like lottery or bingo. The outcome of winning or losing depends on predetermined results for a fixed number of spins.
Jackpot Types
There are two general categories of jackpots: fixed and progressive.
In fixed jackpot slots, a set winning combination pays out a big prize regardless of the amount bet by the player. In progressive jackpot slots, a portion of every bet made by the player is added to the prize pool, which accumulates over time. The prize pool is reset when the jackpot is won.
Progressive jackpot slots may be:
- Standalone – the jackpot is linked to a single machine
- Local – multiple machines of the same type are linked together
- It's important to familiarize oneself with these differences when choosing on what jackpot game to play.
Online Slots

Slots also vary depending on the number of paylines. Some have just one payline, while others provide hundreds or thousands. The player always has an option of choosing that game which is in line with their preference and style of play.
