Alien Robots is a 5-reel video slot that has 30 fixed paylines and a side bet that activates a 243-ways-to-win playing structure. A player may adjust two wagering options: a coin value ($0.01 to $0.5) and a bet level (1 to 5), thus a total bet may vary from $0.3 to $75 per spin, in a regular game. Making a side bet doubles the amount of your main bet, so the maximum possible wager reaches $150 per spin. Alien Robots has a wild symbol that substitutes for all icons other than the scatter which in this slot is a Flying Saucer. Hitting three or more UFOs in any position activates 10, 20 or 50 retriggerable free spins, during which any wild symbol that lands on the reels expands up and down to cover the entire reel and then triggers a respin bringing you more wins. The highest jackpot in the game is $50,000; this is awarded for getting 5 Red Robots on a payline.
