Choosing slots worth playing
Slots make up most of the game library at every casino on this page, and the differences between them are larger than they look.
RTP is published for a reason
Return to player is the proportion of stakes a game returns over a very long run. Most slots sit between 94 and 97 percent. That range is the difference between a bankroll lasting an evening and lasting an hour. The figure is usually in the game's information panel, and some operators run the same title at a lower RTP setting than others.
Volatility decides how it feels
A low-volatility slot pays small amounts often. A high-volatility one pays rarely and larger. Neither is better, but they suit different budgets. High volatility with a small bankroll is the fastest way to a short session.
Free spins are not all equal
Look at the spin value, the games they apply to, the expiry window and whether winnings arrive as cash or as bonus funds subject to further wagering. A hundred spins at ten cent with 40x wagering on the winnings is worth far less than the number suggests.
Jackpots
Progressive jackpot games usually carry a lower base RTP, because part of every stake feeds the prize pool. Some require a maximum bet to qualify at all. Check both before playing one seriously.
