Crystal Sun Game Overview

Starblast was the original name of Crystal Sun, but it had to be changed because it was too similar to the Starburst slot. The original game was taken down but has now been re-released with a less noticeable name. The main difference between the game and Starburst is that Crystal Sun offers higher variance and a maximum potential win of up to 4,000x your wager.

Five reels, three rows, and ten paylines that pay both ways are present in Crystal Sun. The game’s Expanding Wild Re-spins are its main feature. Also, the key distinction is that those expanding wilds may land with a multiplier of up to x3, which, if combined with all 3, could increase your wins by up to x9.

The fact that Crystal Sun has a higher RTP than Starburst is also another fantastic feature of the game. It has an RTP of 96.6%, which is respectable considering that this game has high volatility. 

The game is relatively basic. The wilds can only appear on the three middle reels. If they do, the wilds spread to completely cover the reel, awarding a respin while the wild reel is fixed in place.

The Crystal Sun slot is available to play online here at our fast withdrawal online casino, King Casino.

How To Play Crystal Sun Slot

  • Sign up to King Casino.
  • Load the Crystal Sun slot.
  • Check the paytable by clicking on the ‘i” icon.
  • Place your wager with the “-” and “+” buttons below the reels. The stake range is from £0.10 up to £50 per spin.
  • Hit the green spin button to start the game.


In addition to two high-value symbols, Crystal Sun has five low to middle-value symbols in the shape of coloured gemstones. To win, you need to land at least three matching symbols on a payline.

The symbols’ payouts for 5-of-a-kind along a payline are as follows:

  • The highest-value symbol, 3 Diamonds, awards up to 16x your stake.
  • Red 777 awards up to 8x your stake.
  • Green gem awards up to 4x your stake.
  • Orange gem awards up to 3x your stake.
  • Red gem awards up to 3x your stake.
  • Yellow gem awards up to 2x your stake. 
  • Purple gem awards up to 2x your stake.

Expanding Wild Feature 

Crystal Sun is simplistic and does not have many extra features. On reels 2, 3, and 4, you may land an expanding wild symbol that could fill the entire reel. 

As a result, the Wild Re-Spins feature becomes activated, giving you a new spin with the expanded wild (or wilds) locked in place.

If you land an additional wild during the Re-spin, it can also expand and award you another Re-spin. This feature can award you up to 3 Re-spins altogether, along with 3 middle enlarged wild reels. Each wild may land with a multiplier of up to x3, and they can combine, which could result in a multiplier of up to x9.

Return To Player

Return to Player (RTP): 96.6%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
