Slots come in all themes, styles and designs, so deciding which one to play is not always an easy choice. You may choose to eliminate which slot to play by gaming provider or volatility whereas the more elite slot players will determine which slot to play based on the Return to Player (RTP).
After all, the highest RTP slots will pay out more, in the long run vs. those with a lower theoretical return to player.
Quick Facts That Are Good to Know:
- RTP = Return To Player
- Volatility = How swingy the game is
Volatility explained: A player can expect less, but bigger wins on a high volatility slot, vs. regular, small wins on a low volatility slot.
RTP explained: Return to Player percentage (RTP) is a theoretical percentage of all money wagered on a slot machine (or other casino game) which will be paid back to us – the players – over time. This is a number based on an infinite amount of time and spins. RTP is just the flip side of house advantage.
House Edge explained: A slot machine; Rainbow Riches: Home Sweet Home has a 2.25% house edge. This means that for all money wagered on this game, the theoretical Return To Player would be 97.75%
Note: This list will be updated on a monthly basis, should we review a game that has a higher RTP than those listed below.
