Understanding Online Slot Games

Online slots can look very different from one another, but most are built around the same core features. Learning terms such as RTP, volatility, paylines and jackpots makes it easier to compare games and understand how they are designed to play.

Return to Player (RTP)

Return to Player, usually shortened to RTP, is the theoretical percentage of money wagered on a slot that the game is designed to return to players over a very large number of spins. For example, a slot with a published RTP of 96% has a theoretical long-term return of R96, NZ$96 or £96 for every 100 wagered.

This percentage is calculated over a long period and does not predict what will happen during an individual playing session. Players can win considerably more or lose considerably more than the published RTP would suggest over a small number of spins.

Slot Volatility

Volatility describes the general risk and payout pattern of a slot. Lower-volatility slots are designed to produce smaller wins more frequently, while higher-volatility games tend to produce wins less often but have the potential for larger payouts.

Neither type is automatically better. Instead, volatility helps players understand the type of playing experience a particular slot is designed to provide.

Paylines and Ways to Win

Traditional online slots use fixed or adjustable paylines that determine which symbol combinations produce a win. Modern games may instead use systems such as Megaways, cluster pays or ways-to-win mechanics that do not rely on traditional paylines.

The number of paylines or ways to win does not indicate how likely you are to win overall. Factors including RTP, volatility, symbol values and the game’s mathematical model all contribute to how a slot performs.

Bonus Features

Free spins, wild symbols, scatter symbols, multipliers, expanding symbols and bonus rounds are common features in modern online slots. Certain games also offer cascading reels, expanding grids, respins or bonus-buy features.

Although these features can change how a game plays, players should still consider the RTP and volatility rather than assuming that a slot with more bonus features offers better returns.

Progressive Jackpot Slots

Progressive jackpot slots have prize pools that increase as players place qualifying bets. In some cases, jackpots are linked across several games or casinos, allowing the prize pool to grow considerably before somebody wins it.

Jackpot slots can offer very large top prizes, although the jackpot itself may be difficult to trigger. Some games also use a different RTP for the progressive jackpot element.

Play Slots for Free

Free-play or demo slots allow players to try many online slot games without wagering real money. This can be useful for learning the rules, paylines and bonus features of an unfamiliar game before deciding whether to play it for real money.

Where available, our slot pages provide information about the game and its features so readers can understand how it works before playing.

How We Review Online Slots

Our slot reviews focus on the information players need to understand how a game works rather than simply whether it looks entertaining. When the information is available, we check the game’s published RTP, volatility, paylines or ways to win, maximum payout, bonus features and the software provider behind the game.

What We Look At

When researching an online slot, our team considers:

Slot specifications can change, and casinos may offer different versions or configurations of the same game. For that reason, we check information against available provider and casino sources and update our slot content when significant changes come to our attention.
