What Features Give Slots Players the Biggest Win Potential in 2025?

Slots have been hugely popular for a long time, since the first mechanical machines were introduced in the 19th century, right through to today’s sleek online versions. Many new features have been brought in during that timespan, and it’s worth looking at them to see which are most popular right now, and how they’ve gained thousands of fans by offering tempting prizes.

This list of current casino games includes titles such as Coins of Leprechaun Hold & Win, 3 Pots of Lunar Wolf Hold & Win, and Super HotChilli Hot & Win. This intriguing variety of themes from around the planet confirms that the Hold & Win mechanism is now widely used on slots with many different themes, but how does it work?

While the mechanism varies from one casino game to the next, this is generally a bonus round where landing certain symbols leads to the player getting a chance to spin the reels again. Special symbols then land during these spins, giving the chance for big wins. The re-spin round may include extra features, such as locked symbols and the chance to earn more spins.

Coins of Leprechaun Hold & Win is an Irish-themed slot based on the leprechaun mythology and played over three reels. When three bonus symbols land, three re-spins are awarded with the special symbols locked in place. Mini, minor, major, and grand jackpots can all be won during this bonus round if symbols showing any of these prizes land. Of course, it’s far from on its own – the Coins of Poseidon slot is another popular Hold & Win game with a mythical theme, calling on the Greek Gods for inspiration in this case.

The idea of a progressive jackpot that climbs every time someone plays the game and doesn’t win has been around for a long time. Today, though, it’s more popular than ever.

The increasing popularity of online slots has allowed progressive jackpots to be offered in many new ways. It’s now easy for game developers to make online slots that are all linked to a single jackpot, providing bigger win potential. They can also add special features, such as bonus games that need to be completed before a jackpot can be claimed.

Thor Hammer Strike Xtreme Power Pots by Rival Gaming has five mighty jackpots that can be unlocked thanks to the game’s special symbols. Hammers – based on the legendary Mjöllnir that nobody else but Thor can even lift – smash into runes to unlock special features, while the jackpots get charged up as you play. Again, the Gods theme is appealing, this time with the Norse pantheon.

Free spins remain one of the most exciting ways of getting a slot bonus, as they let you play extra games without adding more funds. This kind of bonus is now offered on many online slots, and it’s often the way to access the biggest wins possible.

Most slots simply require you to get a certain number of scatter symbols to earn a set of free spins. As well as getting to play a fixed number of games at no cost, you might also get extra bonuses such as added wilds or special symbols during this exciting round.

If we look at Vegas Space Heist by Qora, we can see a Super Spin Bonus that gets activated when the scatters spell out the word ‘MONEY’ across the reels. This bonus round starts with a 2x multiplier, and the scatter symbols are locked into place as prize icons.

The last example included multipliers, which show that the most interesting features can combine different elements to create something new with big win potentials. Multipliers can apply in online slots in different ways, creating fun and excitement for the players by increasing the variety.

In the 3 Pots of Lunar Wolf Hold & Win game by Betsoft, we see several of the elements that we’ve been looking at thus far. As well as the Hold & Win mechanism mentioned in its name, there are jackpots, free spins, and multipliers.

These days, online slots have a variety of ways of adding multipliers to boost their prizes. They may just land randomly on any symbol, or they may be part of a bonus round where special conditions need to be met. Increasing multipliers tend to be the most valuable, as they give each win or spin an ever greater boost.

All of these features add variety to online slots without taking away the simplicity that has made these games so well-loved. The popularity of slots has grown over the years as new features get added, with no sign of this trend ending any time soon.
