How Much Can I Win Playing Online Slot Games?

You can win a great deal playing a UK slot game! The desired outcome when spinning those reels is, naturally, to claim the grand jackpot. Jackpots vary from game to game. As we discussed earlier, some slot titles offer progressive jackpots, of which the value climbs higher as players place each bet. Other online slots have fixed jackpots, such as Jack in the Box’s grand cash prizes which is a whopping 600x your stake.

With cash stakes high as £250 in some games, there are many incredible opportunities for a significant max win. Progressive jackpot slots such as Mega Moolah can reach jaw-dropping values – millions of pounds in some cases and for obvious reasons are hugely appealing for many gamblers. Jackpots are won by playing an online slot using the max bet and It is usually more difficult to win the super high-value jackpots, but somebody has to claim it eventually, right? 

What Traditional Slot Machines Can I Play Online?

Our Slots site has a catalogue of over 900+ gambling titles and there are over 50 traditional slot machines available to play at Spin Bonus. Our traditional online slot machines hold much appeal for many keen gamblers thanks to their offering of simple gameplay. Our classic slot machines are some of the most well-regarded titles in the casino industry and are provided by the leading developers of real pub slots like Barcrest and Big Time Gaming.

What Video Slots Can I Play On Spin Bonus

We have so many variations of video slots online that it can be a real challenge, especially for our new players, to settle on a type of game to play. From progressive jackpots to Megaways games; slot machines with ‘cascading reels’ to ‘cluster pay’ features.

How Do I Choose The Right Slot Game To Play?

To ensure you are well-informed when it comes to the different slot game options, here is a selection of the most popular types.

Megaways Slots

Megaways offers a thrilling new twist on the traditional slot game with 5 reels and a fixed quantity of paylines. Every time the players clicks spin, the potential ways to win changes. The Megaways slot list is extensive, Some of our best Megaways slots offer up to 117,649 varying ways to win, such as the well-loved Piggy Riches Megaways, Rainbow Riches Megaways, Fishin’ Frenzy MegaWays and Reel King Megaways. If you haven’t tried a Megaways slot game yet, make it your priority!

Classic Casino Slots

In our classic slot games, you won’t find hundreds of paylines, an abundance of bonus rounds and free spins. Stick with nostalgic fruits, bars and sevens, minimalist imagery, one simple bonus game (maximum – often there will be no bonus feature) and between 1 and 5 paylines. Burning Wins: Classic 5 Lines is just one of the top classic slots we have.

Cluster Pays Slots

A highly popular example of a cluster pays slot is Aloha! Cluster Pays by gaming giants NetEnt. Our slot games offering a cluster pays feature often share the same characteristics as many regular online slots, however ‘cluster pays’ results in an interesting variation on paylines This unique cluster formation element removes the traditional side to side payline feature, resulting in you aiming for clusters of like-symbols in order to win. The exact number of symbols may vary depending on the game, but generally, the symbols are required to land adjacent to one another, forming a group.

Cascading Reels

Cascading reels – or tumbling reels – are much-loved in the online slot industry thanks to their potential for truly spectacular payouts, an abundance of free spins and bonus games. Cascading reels replace traditional spinning reels, as any symbols forming a winning combination following your spin disappear from the reels, followed by replacement symbols tumbling into their place and hence, the possibility of further winning combinations. This can create an impressive win streak for lucky our players. Cascading reels can sometimes be found in conjunction with other online slots features such as Megaways.

Jackpot Slot Games

Jackpot slots games differ from our regular slots as their jackpots aren’t fixed. Instead, they are progressive; in other words, every time you and other players wager and spin, the overall jackpot value increases. Of course, the more players, the larger the jackpot, with some progressive jackpots reaching as much as millions of pounds.

When the jackpot is won, the value defaults back to its base value and begins to increase once again as you play. The possibility of winning a life-changing sum of cash – often of much higher value than top payouts in non-progressive jackpot slots – is the main appeal of jackpot slots for many of our players.

Jackpot King Slots

Jackpot King Slots are extremely popular and huge sums of cash can be won. There are three different jackpots in one game and each one could be won on any single spin.

Are the Slot Games we Feature Fair?

The online slot games we feature are completely fair to play. The games rely on a series of complex, computerised algorithms to determine when the reels of a slot are spinning, which ultimately determines the outcome. This process in itself could be at risk of manipulations, therefore software developers use a process called the Random Number Generator to ensure fair play. This ensures the outcome is an entirely random one; and one that cannot be predicted.

A slot game has no memory, so players are not “due” a win after a series of losses and every player has the same chance of a payout as everyone else. Our slot games also have a validated RTP (Return to Player) value which is the percentage of your bet that you should expect to win back.
