What Are Online Slots?
For those new to the topic, slots are games where you spin reels to form winning combinations called 'paylines'. Matching symbols on these paylines result in prizes. Online slots are digital versions of traditional slot machines and can be played on desktop, mobile, or tablet devices. In the UK, slots are sometimes called Fruit Machines or Fruities, while in Australasia, they are referred to as Pokies.
While the basic concept is simple, modern online slots stand out due to their adaptations and innovations. A wide range of themes and gameplay features gives these games a significant edge over outdated land-based slot machines.
Key Aspects of a Good Online Slot Game
RTP & Volatility
A quality slot game typically features a medium to high Return to Player percentage (RTP%). The higher the RTP, the better the payouts. A reasonable RTP is around 96% or higher, which is the industry average. However, some games with lower RTPs can still be worthwhile, especially if they feature large progressive jackpots or unique mechanics where the RTP increases the longer you play.
In-Game Bonus Features
Modern online slots come packed with exciting bonus features that enhance gameplay and increase winning potential. Popular features include:
- Free spins
- Re-spins
- Multipliers
- Wilds and scatters
- Expanding reels
- Colossal symbols
- Avalanche or cascade reels
- Win-both-ways paylines
- Pick-and-click features
- Gamble features
- Megaways mechanics (243+ ways to win)
These features provide engaging and dynamic experiences, making modern slots far more appealing than classic, first-generation games.
Thrilling Themes
A compelling theme can make a slot game more enjoyable. Popular themes include:
- Fun cartoon characters
- Viking and Norse mythology
- Magic and mystical stories
- Space and sci-fi adventures
- Seasonal themes (Christmas, Halloween, Easter)
- Ancient Egypt-inspired slots, like Book of Dead and Book of Ra
Branded slots based on TV shows and movies are also highly popular, including Gladiator Slot, Who Wants To Be A Millionaire, Vikings, and Game of Thrones.
Progressive & High-Value Jackpots
The thrill of winning life-changing sums makes progressive jackpot slots incredibly appealing. Popular progressive jackpot games include Mega Moolah, Divine Fortune, and Age of the Gods. While massive jackpots are rare, smaller daily jackpots or 'Drops & Wins' (commonly provided by Pragmatic Play) are great options for players looking for frequent payouts.
Minimum & Maximum Bets
Understanding a slot's betting limits is essential. Slots with higher maximum bets often have better payout potential, particularly for jackpot games that require a max bet to win. Always check the game rules to understand how bets impact payouts.
Mobile Slots
Modern slot games are developed using HTML5 technology, ensuring seamless performance on mobile devices. However, older slots may not always be optimized for mobile play, so it's worth verifying their compatibility.
Understanding RTP %
Return to Player percentage (RTP%) indicates the average amount a player can expect to win back over time. A higher RTP increases your chance of winning some funds. While most slots have a fixed RTP, some games feature dynamic RTP values that increase as you play.
