Engage your robot army in a 5-reel free slot demo game that invites you to a retro-futuristic universe with the goal of exploration and finding the new frontiers of wealth. In this game, you can play on 40 fixed paylines. Character and item symbols are placed in stacks of 2, 3, or 4 symbols on each reel. The A-K-Q-J-10 symbols and wild symbol are not placed in stacked formation. The game includes a wild symbol (Robot), that substitutes for any other reel symbol to help comprise winning combinations. Three or more Robot symbols appearing on any reel will trigger the Robot Revolution free spin feature. 10 free spins will be awarded. During free spins, all wild symbols that appear (including the triggering ones) will be “sticky” on the reels. When the free spin starts, all wilds will remain on the reels but “walk” horizontally to the reel to the left. If the wild is on reel 1, it will walk off the reel and disappear. The free spin feature cannot be re-triggered. Additional free spins cannot be won.
