Online slots FAQs
Do you know the difference between an expanding wild and a scatter symbol? Not to worry, we’ve answered some of the most frequently asked slot-related questions below!
Are slot machines random?
The outcome of a slot spin is determined by a mechanism called a Random Number Generator (RNG) which produces hundreds of thousands of results every second.
RNGs are tested by independent third-party companies to make sure they're compliant and fair for all players.
However, the odds are in favour of the slots provider and casino with the average slot return to player (RTP) varying between 90%-98%. You can find details of these odds in a game's paytable.
Do I need to wager my winnings from a slot bonus?
The majority of free spins bonuses are subject to wagering requirements with some casinos requiring you to play through your winnings up to 80 times the original bonus value.
Casinos like bgo and PlayOJO offer no wagering spins with all winnings paid out in withdrawable cash. Although no wagering casinos aren’t the norm, they’re certainly on the rise with more offers popping up monthly.
Can I play bingo at slot sites and casinos?
We've separated our lists of bingo sites and casinos to help you to quickly and easily choose your next place to play.
While you'll often find slot games on a bingo site, it’s rarer to find bingo rooms at a casino. Use the filter options on our category pages to tailor your search to your preferences.
