What to expect from Virgin Games

The online slots world is so extensive, that it can be a bit overwhelming to know where to start. Many agreed that it is easy to become engrossed whilst playing these games (77 percent), whilst 28 percent reported experiencing a ‘binge’ whilst playing online casino games. Yet, almost a quarter of respondents (24 percent) reported that they spend more than they could afford to lose playing online casino games. Predominantly, across online casino games, those that had spent money on online casino games in the last 4 weeks were aged 25 to 34 years old. The Malta Gaming Authority (MGA) regulate online gambling sites to ensure the operator’s games are fair.

Based around a theme – for example Irish folklore or Ancient Greece – the dynamic gameplay is designed to enhance the user experience. RTP casinos not on gamstop (return to player) is the percentage of all money staked that a slot pays back over time. For example, if a game has a 97% RTP, you should (in theory, at least) get back £97 for every £100 you wager (though this is an average across thousands of spins).
