Whenever you google the name of an online slot game, you will see a huge number of results offering a demo version. These are free slots, games that you can play without opening an account or depositing any funds. 

You can also play free slots for fun at online casinos and gambling sites where you have an account. Just select the play-for-fun option. But playing free slot games for fun is not the only reason you should consider this option. 

Free slots are also a great way to test a game before you risk your own cash. Nowadays, slots come with all kinds of features and bonus rounds and playing a new real-money game without testing it first could result in some missed wins and big losses if you don't know what to expect.

Another example is progressive jackpot games, which are always very tempting thanks to the huge prizes on offer. But they are usually much higher volatility than normal games. Checking out a progressive jackpot slot in demo mode will help you decide if you can afford to play it for a start. 

This is true for any slot game, of course. And it will also help you manage your bankroll if you do decide to play for real. Playing 100 spins or more on a free slot will give you a reasonable idea of the hit frequency, and the size of the average win. This information can help you decide the bet level that will keep you in the game longest while still giving some good winning potential.

Of course, you can’t win real money when playing demo slots. But they are a great way to enjoy a risk-free slot session. And they are also a valuable tool for getting to know a game and managing risk. After all, fun gambling is responsible gambling. Good Luck.
