Our 5 Most Popular Casino Games

Here at Unibet there are hundreds of slot machines to choose from. We’ve a wide set of themes, some of which are set in historic locations such as Ancient Egypt or the notorious Roman Empire. Animals can also take centre stage as cute cats do battle with cartoon dogs while other genres cover horror, Greek Gods, enchanted forests and many, many more.

Players can also pick based on the potential payout but some slots will always rise to the top so, if you are struggling to pick your own favourite, here are the five most popular games in the Unibet Online Casino currently on our list.


5. Koi Princess

We’ll work in descending order and start with Koi Princess. Produced by NetEnt and released in 2015, this title covers a number of themes, starting with an oriental flavour and backed by something of a cartoon, Manga mix.

This is the fifth most popular game on our schedule and while there may be bigger paying slots around, Koi Princess is great fun and it comes loaded with a whole host of cool features. Back in the base game, there are 20 paylines across a 5x3 grid and a set of cartoon symbols to align across one of those betways.

Individual players will have their own reasons as to why they prefer one slot over other titles but with Koi Princess, the key to its appeal lies in a truck load of bonuses. They start with a random feature which can land on any base spin. It’s a pick game involving three koi carp whereby players pick a fish to win a prize. Bonuses at this point include a free spin with wild reels, extra wilds or a guaranteed five in a line win.

The main bonus round is activated when three scatter symbols fall into view. Once again, there is a choice of extra games at this point including free spins, a wheel of fortune feature and a guaranteed win.

Koi Princess also has a bonus bet feature where players can double their stake. This has the effect of increasing the average Return to Player (RTP) numbers from 96.00% to 96.23%. This is a complex game and that’s just one of many reasons why Koi Princess has risen to number 5 on the Unibet charts.

4. Book of Dead

Slots with an adventure theme are always entertaining and the hero of this title is no stranger to the reels. Rich Wilde previously appeared in Pearls of India in that never ending quest to wrestle priceless artefacts from their original, and possibly rightful resting place.

If you’ve ever watched movies that cover this genre then you will understand the obvious appeal but why does Book of Dead stand out in a crowded area of slot machine play? Like Koi Princess, it was produced by an established slot developer - in this case Play ‘N Go. It also has that good mix of entertainment in the base game, coupled with exciting bonus features and the potential for a big jackpot.

Things start off in simple fashion with a small set of symbols in the base game. Unusually for video slots, there is no separate wild and scatter as the Book of Dead itself claims both roles. The main feature is free spins but this round is different to similar bonuses from around the slots. A symbol is chosen at random to be an expanding wild and this can seriously increase the chances of big wins dropping by.

In short, Book of Dead has that classic mix of entertainment and the potential for regular payouts, leading to the possibility of a mighty jackpot. This title has an RTP of 96.21% and once again, that’s comfortably in excess of the UK Gambling Commission’s minimum level of 70%.

3. King Kong Cash

Some classic characters from the silver screen have been immortalised at the online slots over the years. From the horror genre, Dracula and Doctor Jekyll have been acknowledged while movie beasts enjoy particular attention. Godzilla is no stranger to the slots and his great rival King Kong appears in many titles too.

According to Unibet’s account holders, King Kong Cash is the best of these options but why have they made that choice? In this game from 2016, developers Blueprint have turned King Kong from ferocious to friendly as he’s joined by some jungle pals in a cartoon extravaganza. Imagine Kong in peaceful retirement and you’re getting the picture.

King Kong Cash is another classic base game with a 5x3 reel set and 20 fixed paylines. A jackpot of 500,000x coin stake is on the line and clearly that’s one reason why the game makes it to number three on the Unibet charts.

We’re now starting to see a pattern emerge in a game that carries a host of bonus options. These start with a random feature that can trigger extra wilds, respins and more.

As for the main bonus round, this is another complex feature and it’s set in motion when three or more of the King Kong Bonus symbols spin into view. When this happens, players spin a wheel to determine the exact nature of the bonus with a trail game and two levels of free spins up for grabs.

Once again, it’s that complexity that sets King Kong Cash apart from most casino slots. The range of bonus features mean that it’s quite like a video game in nature but with cash prizes at stake.

2. Ted Slot Game

This funny and irreverent character made his way onto the movie screens in 2012 and he proved to be a huge hit with film audiences across the world. Ted - the slot machine - followed in 2017 and he quickly emulated his movie persona as he climbed to number 2 in Unibet’s list of favourites.

The classic elements that we’ve seen in other popular slots are all in evidence here. There’s the entertaining base game with clever graphics and, as we saw with King Kong, we have a recognisable character as the hero. The complex nature of the bonus rounds are also evident as is the chance to win a seriously big jackpot prize.

We begin, as before, with random bonuses: Ted starts the game sleeping peacefully at the bottom of the reels but when he wakes up, he can award any one of a set of bonuses including free spins, multipliers and a ‘Wheel of Fartune’ Round.

Three of the Ted bonus symbols will activate the main feature which, yet again, provides an extensive choice. Known by humorous names including Beer Streak and Psychedelic Super Spin, there are extra bonus symbols and additional spins on the line.

With a strong RTP of 95.80% Ted backs up the fun with the potential for regular payouts and there is a generous 100,000x coin stake up for grabs as the top jackpot prize.

1. Rainbow Riches

Sometimes the originals are the best and, straight in at number one is one of the earliest slot machines on Unibet’s list. Rainbow Riches was first released by Barcrest way back in 2009 and for a game to remain so popular for over ten years, it must be pretty special.

While all of our most popular games carry high Return to Player percentages, we realise that there is an element of luck in slot machine play. With that in mind, it makes sense to channel the luck of the Irish and this is one of a host of games that carry the theme of the Emerald Isle.

Classic slot symbols include leprechauns, a pot of gold and a wishing well and they’re all in evidence here. Line them up for slot wins alongside generic symbols from a standard deck of playing cards.

Bonuses are plentiful and they include rounds called Wishing Well, Pots of Gold and Road to Riches. This is classic slot machine play with a pick game, multipliers and a wheel of fortune.

Why does Rainbow Riches stand out from a host of slots that carry the Lucky Irish theme? You’d have to ask each of Unibet’s account holders but we think it’s the fun graphics and, once again, a wide set of bonuses that keep players interested on every spin. It’s also rare for such an early slot to have so many additional features so maybe that’s why Rainbow Riches has been such a hit for so long.
