What Are Space Slots?

Slot machines that are centered on the concept of space are referred to as space slots. These typically incorporate various space-related symbols, such as extraterrestrial beings, planets, galaxies, spaceships, astronauts, explorers, space missions, and so on.

Space slot machines have thrilling storylines, which, in combination with awesome soundtracks and fun graphics, make the gameplay that much more enjoyable. Not to mention, a plethora of bonuses and rewards are awaiting you right when you start playing space slots.

How to Play Space Slots Online

To begin, before you start looking for suitable space slots to play, you have to choose the kind of game that you wish to engage in. For example, you should decide which form of a slot machine is more appealing to you—the traditional one with three reels and one payline or a high-tech video slot machine.

This choice may affect not only the rules of the game but also the tactic that will provide you with the greatest opportunity to win.

Additionally, you should think about the bonus rounds and any other unique features that can make your playing experience more interesting. Most space slot games come with generous return-to-player percentages (RTPs), a significant amount of free spins, and hefty jackpots.

Starburst is a slot game developed by NetEnt, featuring 5 reels, 10 paylines, a maximum payout of 500 times the wager per spin, and an RTP of 96%.

If another expanding Starburst Wild appears during the respin, both expanding wilds will stay in place for a third consecutive respin.
