Alien Spinvasion is an outer world themed online slot machine game with cool outer space graphics and symbols. You will win when matching symbols are displayed on the active pay line. All symbols pay from left to right, starting with the leftmost reel. Scatter wins are multiplied by the total credits wagered. Scatters are paid in addition to pay-line wins. Wins are multiplied by the bet per line. Regular symbols include Earth, Telephone, Space Rocket, Alien Egg, Ray Gun, Meteorite, Flying Saucer, A, K, Q,  J, 10, and 9.

The Alien head with one eye is a Wild and will replace any other symbol to form a winning line, when possible.

Sticky Wilds will remain on screen and trigger re-spins whenever they are part of a winning line. Additional "Sticky Wilds" will trigger additional re-spins, and sticky wilds will again remain on-screen during ALL re-spins. Sticky Wilds only appear during regular spins. When the Army General appears on screen, you will win 11 free spins. During free spins, all icons become drop icons.

Any drop icon win will trigger the Drop feature. The drop icons that triggered the win will disappear, and the icons above them will fall to fill the now-empty spaces. These icons can not pay more than once during a drop sequence. As far as coin size your options are 0.01, 0.05, 0.10 and 0.25. You can bet from 1 to 10 coins per line on up to 50 active pay lines. Only the highest win is paid per selected line and all wins pay left to right except Scatters which pay any. Click the "Spin" button to spin the reels and form a combination of icons on the pay lines to win the jackpot.

Payouts are made according to the icons and their values on the payable.
