How to Play

Follow a guide below to start playing the Coba slot

  1. Find the title in the casino's game library
  2. Start the slot and wait until its content is loaded
  3. Click to continue and proceed to the main board
  4. Click on the coin icon and select the bet size. The min bet is €0.2, while the max is €100
  5. Check rules and paytable if you want to
  6. Start spinning the slot manually or automatically

Coba is not your typical slot, as there are no reels, and the grid has an unusual size. The board has 7 horizontal and 6/7 vertical rows.

The slot's mechanics combine cluster-pay and cascading (Avalanche). You need at least 5 connected symbols of a kind for a winning cluster. Once you get a winning collection, symbols from it will disappear and be replaced by symbols from the above positions, while new elements drop to fill empty spots. Spin continues as long as you get new winning clusters.

Note that symbols here are hexagonal, meaning they connect with 6 other elements at a time. Symbols drop with gravity and repeatedly slide to the left and right as far downwards as possible.

Coba RTP and Volatility

The RTP of Coba is 95%, while the slot's variance is medium.

The medium volatility of the slot is good news for those who want to eliminate durable down streaks. You'll be getting wins quite often in this game, as its hit frequency is 40%. Even activating snakes is not that rare. So, you are safe from a dead spins boredom here.

The level of payback is 95%, which is below the industry average. The slot doesn't have a separate bonus round, but we think that winnings from snakes cover more than 60% of RTP.




Coba is the slot about gems, snakes, and ancient Aztec civilizations. There is a lot of gold and jewelry and mystic pictures of animals on stones. The atmosphere is mysterious, with a piece of tribal music and noises from animals. You can feel that you are here to learn the secrets of an extinct civilization.

The looks and sounds of the slot make the game even more attractive, especially with details like a snake progress bar or a background picture of a tomb in the jungle.

Only 7 symbols are present in the game, and all of them a regular.

The first group of elements is stones with different pictures. The second group is gems and a coin. Here is the fill list of all symbols for winning cluster of 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15+ elements: a rabbit stone, a skull stone, a dog stone, a green gem, a blue gem, a red gem, and a golden coin. The Wild symbol is not a classical one because it substitutes for all paying symbols but it also functions as a multiplier.

About ELK Studios

ELK Studios is a fast-growing and innovative slot developer from Sweden. The company was founded in 2012, declaring the mobile-first mentality from the start. In the first 3 years of its existence, ELK released only 6 games, but since 2015 the company has been releasing a new title every month.

The content of ELK is easy to detect due to phenomenal graphics, non-trivial themes, and unique features. The company implemented gamification elements like betting strategies and was of the very first providers that added a bonus buy option to its slots. Their X-Tier feature is one of the best casino innovations of past years.

ELK is not only about slogans and big talk. The company received recognition in industry awards, winning some prestigious nominations. For example, Wild Toro brought the "Slot of the Year" award at EGR in 2017. And it's not even the most popular slot from the studio, as they also produced hits like Poltava, Pacific Gold, and Taco Brothers series.

Bonus Rounds and Free Spins


The game is about snakes and their actions. So, let's learn about them!


You can see the meter on the left side of the slot's interface. Every symbol from the winning cluster fills that meter. You can reach 4 levels in that meter to get snakes on the gaming board:

  • 1st level – 1 snake;
  • 2nd level – 2 snakes;
  • 3rd level – 3 snakes;
  • 4th level – 6 snakes.

For example, to reach 1st level, you need 25 winning symbols from one spin/respin. The meter resets after each respin.

Snakes appear from the right or left side of the board from the special golden nests. Snake is basically a moving winning cluster with a length of at least 5 elements. It moves randomly in different directions. The symbol of that winning cluster is the first symbol a snake moves to after its appearance or after respin. You'll see that symbol on the snake's head. All the following symbols the snake moves over will be transformed into Snake Symbol and become part of the snake (winning cluster), indicated by a golden frame around elements.

Snake has two modes:

  • Survival, which can be indicated by the yellow tail;
  • Non-survival, which a blue tail can indicate.

Survival mode means the snake will last for the next symbols' drop. Non-survival mode means that the snake will disappear. The non-survival mode can be turned into survival if the snake moves over the same symbol as the Snake symbol. She will eat that symbol, get +1 extra step (+1 symbol to winning cluster) and survive for another drop.

Snake is always in survival mode after its appearance, meaning it will survive the next drop, and always in a non-survival mode for the following fall after its arrival. If the snake in a non-survival state doesn't eat the same symbol as the Snake Symbol, it'll die and be removed from the board.

During the snake movement, two types of crossing can appear:

  • Two snake crosses. The symbols of crossing become an 2x wilds. Every new crossing in the same spot doubles the wild multiplier.
  • Snake crosses and bites its body. In that case, it dies.

If few multiplier wilds exist in the winning cluster, their values will be multiplied.

Even 10x wins are rare without snakes, as you need a big cluster for good odds.

Overall Rating

Coba is one of those slots that can turn you into a fan from a few spins. It's an incredibly playable game with exciting gameplay and great looks. And what's even better is that you can get huge wins here.

Hexagonal symbols are a reasonably new concept, and it's great to see it developing. The slot surely deserves your attention if you are into cluster-pay/cascading genres.

What a slot. Never played anything like that!
It's both weird and exciting. Combo of cascades and cluster pay with a super weird “SNAKE” feature. Basically, the whole gaming process is about snakes. Ur aim is to get a combo of cascades to let snake crawl into board and eat symbols. And then more snakes will appear.
The game is volatile, as you can get snakes 3-4 spins in a row and then go on 40-50 series without them. W/o snakes it’s a waste of time and money ofc, as it’s the only feature.

ELK studios decided surprise one more time, with their own interpretation of a snake game. Coba is a highly volatile slot with an interesting concept of creating snakes that transform symbols and add wilds with increased multiplier. I wish the RTP was higher for this slot, since it does have a huge potential. Beware, that snake tends to eat itself and then it just disappears ending the feature. I did like the game a lot, since it is fun to spin for sure, especially when you have 6 snakes.
