For years slot developers have revisited Mayan culture looking for inspiration for their games. Peter & Sons, working as part of the Yggdrasil Masters program, have finally decided to come at the time period from a different angle. Xibalba is what the Mayans believed was the underworld and it makes for an incredibly interesting theme for an online slot game. The slot is more than just a quirky theme though, it also comes loaded with a selection of bonus features. Let’s take a more detailed look at the game in this Xibalba slot review and see what else is on offer.

When we loaded up the Xibalba online slot game, its bold and quirky design instantly stood out. The action takes place deep in the underworld in what appears to be some sort of cave. The reels themselves are made up of rocks that are trapped, with people wearing tribal masks and skulls standing around. Peter & Sons have a habit of creating quirky titles though, so there is nothing to be scared of here, with the whole thing having quite a vibrant, cartoonish feel.

The gameplay in the Xibalba slot games isn’t without its quirks either. The action starts on a standard 5x3 grid you would find in most top online slots at the newest online casinos, but it can expand with every win. The slot uses a Cascading Wins feature that replaces winning combinations with more symbols. When this happens, reels can expand the game can end up taking place on a 6x5 matrix with consecutive wins. Things start with 243 ways to win but can max out at 7,776, which is quite the step up.

The slot is fairly flexible when it comes to budget. The minimum you can bet when you play Xibalba for real money is $0.10, while the maximum is $50, which is a good wagering range, especially for more conservative players.

Peter & Sons and Yggdrasil like to make sure that their games are easily accessible. Xibalba has been developed using HTML5 technology. This means it will run on mobile devices and you should have no problem with the game being supported on different platforms and operating systems.

Xibalba comes packed with some excellent bonus features. As we’ve mentioned, whenever you land a win, you will trigger a cascade effect and expand the reels as well. On top of this, there is a Win Multiplier that increases by one with every win. This will all continue to grow until you fail to score a winning combination.

This is not the only way to secure some re-spins though. If you land two Scatters on reels 2, 3, or 4 will reward you with the Gigantor Symbol. This is a 2x2 or 3x3 Wild that will lock on the reels and reward you with an extra re-spin. It will stick in place until the end of the winning cascade.

Talking of Wild Symbols that stick around, there is also an expanded Yellow Serpent Wild that will fill the full reel when it appears. Unlike standard symbols, it will not disappear as part of a winning combination and will stick on the reels until the winning cascade is finished.

Finally, the slot also has a Bonus Free Spins Round. This is triggered when you land three Scatters anywhere on the reels. It will give you 15 free spins. As well as this, the Winning Multiplier does not reset after the end of a cascade and continues to grow throughout the round.

Depending on which top online casino you are playing at and your location, you may be able to buy your way into the bonus rounds. This will cost you 77x your total stake, so think carefully as to whether you think it is worth it.

The Xibalba return to player is listed in the game’s information as 96.10% and it has been given a high volatility rating. The maximum win that can be secured in the slot is 20,000x your stake, which is a solid number that will no doubt please a lot of players. It's even better if you are lucky enough to hit the max payout while playing with one of the best online slot bonuses recommended on our site!
