Let’s travel back to ancient times in the Evolution video slot from NetEnt. Mix history with stacks of cash as you hit the winning combinations in this game, which can be enjoyed for free or with real money at most certified casinos. NetEnt is one of our favourite game developers, and they keep delivering great games with the speed of light. This slot consists of 25 paylines, with ten bet levels available. Choose coin values from 0.01 to 0.50, with a minimum bet set at 0.25, going all the way up to the maximum bet of 125.00. You can win as much as 44,000 in one win.

Theme, characters and environment

Game theme

When we start this game we enter a world under water, where life emerged at the very beginning of our evolution. It is a very sci-fi feel to this game, and symbols are pre-historic animals, plants and creatures from a time before humans, before animals, even before dinosaurs. As you would expect, all symbols in the game are represented by creatures from different stages in the evolution, and they float in this water on the transparent reels, bringing Fruit Warp to mind because of its outer-worldliness. Somehow this pre-historic game feels more like it came from the future.

Environment and atmosphere

In the main game, the goal is to get matching symbols as always. There are a total of 25 paylines in Evolution, and you can increase the bet level from 1 to 10, with coin value ranging from 0.01 to 0.50. Play for free or with real money, it is a great experience either way. Wild symbols are also present, increasing your odds of getting winning combinations because it substitutes for all other symbols except for the scatter. To enter the generous free spins feature, we need to get at least three scattered Free Spin symbols anywhere on the reels.

Symbols and soundtrack

Symbols and sound

The five lower-value symbols are not your usual play cards, although they have kept the letters and the numbers. Each symbol is beautifully animated and when you hit a winning combination, the symbols appear to explode in a halo of colour. As the value increases, so does the complexity of the creature, although you may not have thought of this unless you are a biologist:

  1. 10 – Primo blobulus
  2. J – Blobulus astrum
  3. Q – Jellocus finnum
  4. K – Jellocus squidae
  5. A – Crustacio springum

The five symbols that have a higher value than those above also become more developed as they increase in value. Listed here from the lowest to the highest value:

  1. An Albus slugus
  2. A Bestla dentum
  3. A Basilisk hairicus
  4. A Basilisk pluma
  5. Draconius rex

Special symbols

The ‘Wild’ symbol is wild and only appears on reels 2, 3, 4 and 5. The ‘Octopus Wild’ symbol is also wild, only appears on reel 3 and doubles all wins it contributes to. This game only offers one bonus game features, which is the free spins feature. It is activated when a player gets at least three of the ‘Free Spin’ scatter symbols anywhere on the reels.

Music and sound effects

A new-age soundtrack really adds to the ambiance in this game, and it is a perfect match to the floating pre-historic symbols. The soothing sound of bubbling water also plays when you spin, unless you hit a winning combination, which activates more upbeat futuristic music. Overall the quality of the soundtrack and the sound effects match the graphics in terms of quality. It is one of those soundtracks you could keep going in the background for a long time without being bothered by it at all.

Bonus options

Bonus options

The main game is really nice and interesting, but this slot game gets way better when you enter the bonus realms, with free spins, evolving symbols and varying multipliers. NetEnt has managed to create something truly unique and inspiring here. The most favourable symbol in this game is Free Spin symbol, with a design that reminds us of fireflies. Get a minimum of three to unlock the super exciting Evolution Bonus Game.

Free spins

If a player gets to the free spins bonus feature, he zooms up through the water up to the surface, progressing with the evolution through time, because up on the ground various plant life has started to grow. The music also picks up a bit and takes you out of the slow and morphic underwater experience. Number of free spins is determined by how many symbols appear in front of the player. There may be up to five symbols, which translates into 20 free spins, and it is a varying multiplier that sets the wins. When you get a winning combination in Free Spin, the Evolution feature is activated.

The Evolution feature

In the Evolution feature all symbols involved in win will “evolve” to the next level. So a Jellocus squidae would become a Crustacio springum, and the lower-value character is removed from all future Free Spins. Imagine what this means over time, as each time you enter the Evolution feature the entire game evolves around you, leading to bigger and bigger wins. The bonus games end with a meteor crashing into earth, turning everything red in a giant explosion. You then sink back under the surface of the water, and continue playing in the main game. Then you are back to looking for the bonus symbols that will active that exciting Evolution Bonus Game once again to continue this evolution process.
