This is 5 reels and 243 ways to win slot powered by Microgaming software. I think that you need to be a space or UFO geek to like this kind of slots. The Galacticons has only one feature called Big Bang Feature. You need 3 or more sun scatter symbols to trigger 10, 15 or 20 free spins respectfully. The free spins are only the start of the bonus round. There is a big hole that floats on the reels after every spin and reacts differently every time. If it lands next to the spaceship or one of the characters it awards you with a multiplier that goes up to x 5. If it lands next to the scatter it gives you one free spin and if it lands next to the Milky Way it will multiply your prize by x 2. This feature is very unique and I have not seen anything similar like this before. I triggered the feature only once and I got 70 x bet win. The problem with this game is that it is impossible to trigger the free spins, it somehow seems that you are always missing that one scatter symbol. If you trigger them at least once during your session consider yourself lucky.
I had a very long session with this slot and at the end I got nothing. I have lost all my money on this game and it does not seem that this game has the potential to award huge, or, better say, at all.
