4. How To Choose An Online Slot
Choosing an online slot is mostly a personal decision for each player.
The more familiar you become with the subtle differences in each slot game, the more you will begin to prefer one game over another.
Having said that, some factors will decide which game is played.
Not all bingo sites offer every slot game.
Some players prefer to only play Egyptian themed slots, for example.
Higher RTP slots payout more over long-term gameplay. However, for most players, we will never complete the millions of spins needed to achieve the games’ theoretical RTP – so this alone may not be the best deciding factor for choosing a slot game.
Also known as volatility, this is how often a game pays out a win. For example, on average, every four spins vs every ten spins. This feature is not published to players, but you will become familiar with it by playing the games.
Some bingo site slots promotions will only include certain games.
