Starburst XXXtreme Slot Review

When you load the slot the first time, you see a striking similarity with its predecessor. The Starburst XXXtreme slot game includes five reels and three rows, with 9 paylines. The game features various bonus features, such as wild symbols and multipliers, which can increase the payout up to 150x. The symbols are still beautiful purple, yellow, blue, orange,  and shiny green gems, each with its shape. The two high-paying symbols are the lucky number seven and the Gold BAR, the highest-paying symbol in the game, and landing five on a line will pay you hugely.


The Supernova Wild is the main symbol and substitutes all other characters. Moreover, whenever a wild appears on one of the reels of 2, 3, or 4, it will carry a random multiplier value of x2, x3, x5, x10, x25, x50, x100, or x150 and expand to cover the entire reel and award a respin. If you land more than one Wild on a payline, your wins are multiplied by the sum of the multipliers.

Random Wilds Feature

As the name suggests, it can be randomly activated after any spin or respin on the three middle reels.


Expanding wilds trigger the respins feature. Each time a wild expands to cover an entire reel, it will stay in place, and the other reels will respin.

XXXtreme Spins

The most exciting feature of the game is the XXXtreme Spins feature. It is a buy feature. You can purchase XXXtreme Spins when you activate XXXtreme Spins, the game guarantees Starburst Wilds for each spin for as long as you keep the part active. XXXtreme spins cost 10x your bet for one guaranteed Starburst Wild symbol each spin and 95x your bet for two guaranteed Starburst Wild Symbols appearing on the reels in each spin.
