Heading into space can be a dream for many people as planets, stars, the solar system and the whole universe can appeal to many around earth. Play N’ Go have certainly taken inspiration from the popularity that this particular fascination has with many and have turned it into a theme for a top-quality slot game.

The Crystal Sun slot game has been produced by the Swedish developer and helps to provide players with a virtual intergalactic adventure as they look to explore the universe for any hidden treasures that it might contain – we do not mean Aliens, by the way.


To begin our Crystal Sun slot review, we looked at the gameplay aspect as this is perhaps one of the most important things to take into account as to whether a slot game is playable. Indeed, the transparent 5-reel, 3-row grid certainly provides a great feeling although the number of paylines could also make it a hugely appealing game. Despite just 10 paylines being available, the Crystal Sun slot game provides players with the chance to win from both directions of the grid, thus providing two ways to win from each spin.

Speaking of spins, players are able to place bets for as little as $0.10 per spin, with those high-rollers able to stake as much as $100 per spin. Play N’ Go have kept the adjustable values at the bottom of the screen and in the middle of the game panel, whilst there are also the traditional ‘AutoPlay’ and ‘Spin’ buttons to the right.

As to be expected, the symbols represent what can be found in space for the most part – although the higher-value symbols might be a little confusing. The low-value icons are the five small planet-crystals that can be found with purple, yellow, red, orange and green all available with varying values. The green icon is worth the most of them, with 400x the bet available for five to be landed.

The sevens, which appear as a three, are the next valuable as they provide 800x for a winning combination of five, whereas the diamonds provide 1,600x for the same amount.

The game’s Wild is the sun and it features a range of multipliers (1x, 2x and 3x) attached to it. The icon also represents the Crystal Sun slot game’s bonus features!

Feature Bonuses

Although the values of the icons can be rather huge and lucrative in places, it would be fair to say our Crystal Sun game review found that the Wild suns are what makes the game the most enjoyable. Players can look to find out how enjoyable they are by reading below or testing out the game themselves with the Crystal Suns Free Play version above!

Indeed, the suns all have the ability to expand and cover all positions on the reels that they appear on. They will then substitute all other icons on a payline where they can form a win. Each Wild that appears also has the ability to trigger a respin, whereas additional Wilds will provide players with another three respins.

As mentioned earlier, the Wild also comes equipped with a multiplier. These have the ability to add together, therefore players could potentially have a multiplier of 9x on the grid that can then be applied to the win!

RTP (return to player)

The Crystal Sun slot is a high-volatility slot with an RTP of 96.00%, so despite potentially having to wait for a while to get wins, those that appear can be huge!
