Cosmic Heart: Slot Review

Cosmic Heart

Playing Cosmic Heart from High 5 Games for free involves taking an interstellar journey in which you will find multipliers, jokers and black holes. You want to know more? Well, don't miss our review!

Cosmic Heart numbers

This slot has a 96% RTP which is more or less the market average. The game screen consists of five reels of four heights and an extra horizontal reel that is placed on top of the classic reels.

It has 20 pay lines that are only activated from left to right and, therefore, the total bet must be divided by 20 to know the bet per line with which you are playing.

Special functions

Different types appear on the reel above of advantages that can be prizes in credits, multipliers of between x2 and x5, wild symbols that are spread by the reel or by several reels randomly, or the scatter.

The key symbol is two galaxies that come together forming a kind of heart-shaped star. When it appears, it moves up its reel, activating the benefit of the symbol that currently appears on the horizontal reel.

Free spins are awarded when the two galaxies that come together appear below a red ball showing the number of free spins awarded. These spins are played with special reels. You can get more spins if the above explained happens again, up to a theoretical maximum of 100 free spins.

In addition there is also a blue ball with a star that if it appears above the two galaxies that come together, they activate the Pick bonus . This Pick bonus is a minigame in which you must choose green stones until you run out of lives. Each green stone can have a prize of between x1 and x10 the bet or lead to a loss of life. The game ends when you run out of lives, but for every 7 choices the game multiplier is increased by one unit.

The design

In the background we have an image of the vastness of the universe. It is striking that there is no type of animation in the background, since the slot is a bit bland. The music is electronic, but calm and can be heard in the background without stress.

The symbols are different planets, stars, galaxies or stones in space. The animations are somewhat poor. For example, when the Pick bonus is activated we will go through a black hole, but rather it gives the sensation of going through a black circle without further ado.

The prizes

The highest paying symbol for a line of five will give you x100 for your bet per line, that is, x5 the total bet. Five wilds still pay more, specifically x200 the bet per line.

The rest of the symbols pay two of them x50 the bet per line and the other four x10 the bet per line in case of combining lines of five appearances .

Cosmic Heart's opinion

This time High 5 Games has tried, but we think it has not been able to find the key. They have made the effort to offer a game with different bonuses, but it is somewhat difficult to understand and that makes it less attractive. In addition, the design also seems to have fallen a bit short and the animations are too simple for what is done today.

That said, it is not a bad game and the addition of the horizontal roller above makes you want to continue playing to see if you are lucky enough to activate any of its benefits. Try it by playing Cosmic Heart for free and form your opinion.

Released in October 2020, the Cosmic Heart slot machine from High 5 Games takes the player on a journey through the space universe, a cosmic and magical atmosphere takes hold of the reels as soon as you press the spin button and the planets and celestial objects will follow one another in front of you to potentially form spectacular wins.
