While both no deposit bonus games and demo games both allow players to play casino games for free, the huge difference between them is that it’s not possible to win money from demo games. Additionally, casinos will often offer demo games on their site which doesn’t require a player to create an account to play them.
Demo games will be clearly marked with ‘Demo’ or ‘Play for Free’, which allows player to know at all times they there is no possibility to win real money from them. The purpose of playing demo game is to try a game out to see if it is entertaining, while also providing a great opportunity to learn the rules of the game. The demo game will have an automatic start-up with virtual credits or cash amount loaded onto the game which simulates what it would be like to play for real money. At no point would it be possible to convert any winnings made from a demo game into real money, as it is just allowing player to play for fun.
No deposit bonus games on the other hand do allow players to win real money. Although players are able to play for free without an initial deposit, it’s entirely possible to win real money as a result of playing games with this bonus.
