Gamblers who regularly use online casinos like King Casino usually have a personal favourite game. Whatever it is the gambler is looking for, there’ll be a game out there for them. Some gamblers look for high RTP (return to player) percentages, some look for advanced graphics, and others look for enticing game play.

However, there’s one thing that all gamblers will take into consideration when choosing a game. And that’s whether it has great prizes or not. What bonus features are on offer? Does the game offer scatters and wilds? What are the minimum and maximum bets? What’s the jackpot?

If it’s a high jackpot you’re after, look no further than Mega Moolah Millionaires. The current record for the highest jackpot was a staggering £13.2 million. Think what you could do with that money!

Other online slots games with huge jackpots are Gladiator, Cleopatra and Gold Fish – all of which have minimum jackpots of £1 million.

However, what’s important is to also consider the RTP percentage. It’s no use picking a game based on its high jackpot if it’s extremely volatile. Mega Moolah, for instance, has an RTP percentage of 88%, which is pretty low for an online slots game.

Yes, if the prizes are astronomical, the developers have to protect themselves and increase the volatility. But try to find the balance between decent jackpot amounts and high RTP ratings (aim to play on 96% and above).

Gold Fish is a good example of finding this balance. The jackpot value is over £1 million and the RTP percentage is 96%. Sounds like good odds to me.

What else to focus on when choosing a game

Bonus features in the shape of free spins are also attractive to gamblers choosing games. The more the merrier. If the game you’re choosing offers dozens of free spins, you’re essentially getting free money in your online account. Spinning the reels for free is pushing you ever closer to winning a pay-out but without you spending from your e-wallet.

Samurai Split, for example, will offer you 480 free spins if you unlock the prestigious bonus feature by landing the “flag” scatter symbol at least three times.

Three flag symbols will get you five free spins, four will present you with eighty free spins, but if you’re lucky enough to get five, you’ll get a staggering 480 free spins. That’s almost unheard of, and so far, unrivalled in the online slot gaming industry.

Other games with lots of free spins are Siberian Storm (240), Cleopatra (180), and Zeus (100).

Finally, although it may not immediately be the first thing you think of when listing the ingredients of a good online slot game, good graphics make a game popular.

The correlation between the quality of the graphics and the overall game quality is strong. Although there are always examples of ‘retro chic’ and ‘throwback nostalgia’, there’s an unspoken rule of thumb that states that if it looks as though it were designed by a child, avoid it. If they cut corners on the graphics, they probably cut corners elsewhere too.
