Cosmic Heart Slot Review

Cosmic Heart Slot Overview

Based on the interplay between planetary bodies in the expansive setting of deep space, the Cosmic Heart slot is a unique and thrilling game. It also has something of the old arcade game about it, similar to Space Invaders. This space-age slot comes courtesy of High 5 Games and takes place on a 5-reel, 4-row board. There are 20 available pay lines. To win players must match symbols across the various pay lines, some of which are quite surprising. The range of bonus features for this game is extensive with a pick’em bonus game as well as a free spins round. What makes this slot a little different is the ‘Prize Line’ which sits atop the reels. Each box on top of the reels indicates a different prize which helps players build up their score quicker. In addition, there are a total of six different feature symbols available to players to trigger. Bets range from 20p to £20 per spin. The maximum win potential in this game is 10174x your stake. This out of this world slot game is highly volatile and comes with an average RTP of 96%.

Graphics and Theme

Those at High 5 Games have created a theme which is half realistic space imagery and half arcade fun. The hybrid works well. The background for this slot is one straight out of Star Wars, with violet planets looming into view from the left and right across a dark expanse. The symbols helpfully though, are bright mini representations of planets and other astronomical bodies such as imploding stars and asteroids. Bonus games are accompanied by the changing of the setting to different starry vistas, giving the game a feeling of progression through space. The music fits the theme well as an amalgamation of synth-pop, typical of the genre with arcade tracks and sound effects.  The effect is a feeling of playing a traditional arcade game but set in a science fiction movie. Wins and triggers are represented by the Cosmic heart, which is depicted as a golden floating love heart.

How To Play Cosmic Heart Slot

As with High 5 Game’s other slots, players can set their bet per spin and win and loss limits using the menu tools displayed at the bottom of the screen.  Once players have the game set to their liking, they are free to spin the reels as they choose. They can do this either manually using the larger button or by setting automatic spins to the required amount. Wins are generated by matching symbols across pay lines.

Cosmic Heart Slot Features

As mentioned, above the reels in this game, there is a special line of features which indicate various prizes. With each spin, the Prize Line features shift one to their left as a new symbol joins from the right. The symbol on the extreme left falls into the abyss. There are six different symbols in this prize line. Each one represents a different prize.

To obtain the prizes indicated above each reel, players must land a special Wild symbol. This symbol looks like two galaxies are being crossed over each other. Players obtain the prize that is above the reel on which it lands. The range of prizes are indicated by the symbols as explained below.

Pink coin cube -A random cash prize between 2x and 100x.

Blue Wild cube with an arrow pointing down – All symbols on the corresponding reel turn Wild.

Blue Wild cube with random arrows – Transforms between 3 and 20 randomly chosen symbols into wilds.

Green Multiplier cube – Player’s wins are boosted by a random multiplier either: 2x, 3x, 4x, 5x or 10x. If you manage to land any of these symbols together, the multipliers will join. Eg: 2x and 10x equals 12x.

Blue Star with ring – Pick’em bonus game is activated with a random number of lives. If players get more than one of these bonuses, the corresponding number of games are played consecutively.

A red arrow with ring – Free spins bonus is activated with the same quantity of spins that is shown in the symbol. These can also be added together.

The Pick’em bonus game when activated transports players to the ‘cosmic slider’ reel set. In this game, players start with a 1x multiplier and the same number of lives as indicated when you won the prize from the symbol (s). In this game green gems will slide down the reels, each is revealed to win prizes between 1x and 10x multiplier.

The prizes won in this game are then subject to a multiplier which increases by 1 for every seven gems collected. The bonus feature ends when all lives are lost. Lives are lost when a gem reveals a black star symbol instead of a prize.

Lastly, players can also activate a Free Spins round, which again is played on a separate set of reels from the base game. This feature stops when players run out of free spins or when a max of 100 spins have been played.
