Frequently Asked Questions

• Are online slots completely random?

  Yes, slot games are completely random. Every online slot game found in a legitimate, licensed online casino utilises random number generator software which ensures that each and every individual spin of the reels is completely unique and random.

• Is there a strategy to playing online slots?

  Slot games are not a game of strategy, unlike some other casino games.  There is no sure way to beat the system and find a winning formula. However, it does pay for players to be educated in the core mechanics of a slot game such as features, RTP and volatility before playing it.

• Are slots rigged?

  In short, no, slots are not rigged, because they don't need to be. Slots are a game of chance based on statistical probability designed to be in favour of the casino. Over millions or even thousands of spins, the casino will always profit based on the odds (or RTP) of the game and the combinations that land.  In fewer spins, a player can profit, but overall with all players of the game considered, the RTP will become truer and the difference is the casino's profit.

• Can you win money playing online slots?

  Yes, players can win money playing online slots. It's even plausible that players could trigger a bonus feature (such as free spins) or a progressive jackpot, which sees them significantly boost their bankroll.
