When it comes to online slot themes, one that has become increasingly popular over the years is Mayan Culture. While it may not be quite as widely used as ancient Egypt and Greece, it certainly has a foot in the race. The latest entry in this forever expanding genre is Coba, a Cluster Pays slot from ELK Studios set deep in the heart of the North American jungle. Is this just another hastily thrown-together slot with a familiar theme or does it offer some innovative gameplay and good winning potential (hint: it does!) let’s find out in this Coba slot review.
You can try the Coba slot at our recommended online casinos.


One thing that you can always rely on in a Mayan-themed slot is that it will look great. The colors in this game really burst off the screen, with the action bursting to life thanks to some super-slick animations. The reels are bordered in impressive gold, while the backdrop is a stunning jungle with what appears to be a luscious waterfall running, which further helps to build this world. ELK Studios have clearly taken a lot of time and effort to make this slot look great.
ELK Studios has thrown together a really fun slot to play, with the base game utilizing several popular gameplay mechanics effectively. The action unfolds across an enhanced 7x7 grid, with the slot using a cluster-pay system as opposed to traditional paylines. Whenever players land a winning combination, all symbols related to it on the grid will disappear and new ones will fall into their place. This continues to happen until there are no winning combinations left on the reels.
Whenever players score a win, it will charge up the snake meter on the right-hand side of the reels. This will trigger a Bonus Round later which we will get to later in the review. The slot can be played for between $0.20 and $100, which is a solid wagering range that covers most budgets.
Of course, ELK Studios has made sure that the slot is fully optimized to work on mobiles. The game’s vibrant design doesn’t lose any of its magic when it makes the jump to the smaller screen, with the Cluster Pay mechanic and 7x7 grid making it feel like a mobile game. With most new online slot sites supporting mobile play, players will be able to take this for a spin with ease.
There are plenty of great bonus features that help bring the Coba slot game to life. The main feature is the Snake Bonus. This is triggered when players fill the snake meter using consecutive cascading wins. The number of snakes that are launched on the reels is dependent on the number of wins secured. There can be a maximum of six snakes added.
So, what are these snakes? They are snake-shaped clusters of symbols that move around the grid and help to create winning combinations. Each snake is made up of matching symbols and they can add to clusters or even create their own. If two snakes cross one another on the grid, they will become a 2x multiplier wild. Every time this happens, the value will double. Be careful though, because if a snake crosses itself, then it will die.
The slot also uses the X-iter Bonus Buy feature. This allows players to adjust the way that they play the slot. For 2x the stake, the game will release three snakes when it reaches level 1 on the meter, for 10x, the game will start with one snake active, for 25x, it will have longer snakes, for 100x, extra snakes will be released at level 2 and 3, and four 500x, the game will start with four snakes active.
The Coba online slot game has an RTP of 95%, which does put it below the industry average. It does counteract this though with a solid 25,000x maximum win that is going to please a lot of players. ELK Studios has given the game a medium volatility rating.
Mayan-themed slots are everywhere these days, but ELK Studios has done a great job of making Coba stand out from the rest of the pack. The game looks brilliant and is a great showcase for some of ELK Studio's more innovative tendencies. The snake mechanic feels like something fresh, and it really helps to keep the gameplay engaging. While the medium volatility may turn off some players, there is an awful lot to enjoy here, and this is definitely a top slot that is worth taking for a spin.
