There are two main ways of playing for free at an internet casino, but only one can win you money. Many slots providers will let you try their games for free – with virtual money. This gives players the chance to read the paytable, absorb the rules, and see if they like the game. If they do, great, they can switch to the live version and play for real money. If not, well, no problem, it was a free test drive that didn’t cost a thing.
