When it comes to choosing online or mobile slot games to play for real money, there are a number of factors you should take into consideration. These include the game's theme, layout, colours, sound effects and background music, number of reels, numbers of pay-lines, bonus features such as wilds, scatters, expanding wilds, free spins, multipliers and more.
However, one of the most important factors to picking slots is often overlooked, particularly by inexperienced slot players - the RTP.
10 Online Slots You Should Never Play
Short for Return to Player (also known as a payout percentage), the RTP is an average of how much of any currency unit ($,£,€ etc.) is returned or paid out to players in winnings expressed as a percentage. For instance, a slot with a 97% RTP means that over time 97p of every £1 played on that game will be paid out as winnings, while 3p is kept by the casino.
This is not to say if you play this slot that you're guaranteed to get out 97% of what you put in. It means that over time an average of 97% will be paid out collectively to players of the game. In other words, you could spend £100 or more on this slot and not win a penny, or you could spend £10 and win a mammoth jackpot - RTP has no bearing on short-term play.
A slot's RTP is very important because it tells you how 'generous' a slot is. For instance, slots with RTPs in the mid to upper 90s are much more generous than those with RTPs in the 80s. Your aim in any casino is to 'get more bang for your gambling buck' and you can achieve that with slots by choosing games with the highest RTPs and avoid those with the lowest.
The trick is to know which online slot have the lowest RTPs and avoid them like the plague. Unfortunately, not all online casino software vendors publish their slot RTPs, which means you may have to search for them on the web, which is tedious.
