Best and worst bets
Best
A slot whose help screen shows 96% or more.
Avoid
Low-RTP versions of popular slots.
Variants
Payline slots, ways-to-win slots, pays-anywhere grids and Megaways differ in how wins form, not in price. Jackpot slots divert part of the return to a prize pool. Volatility runs from gentle games such as Starburst to very high ones such as Sweet Bonanza.
