What on Earth is a space theme video slot. It has 5 reels and you can play up to 9 lines. The idea is to get three of the same spaceships (scatters) in a row to start the bonus feature. The bonus feature will present a row of aliens to you. Pick one for a special prize, two of which will take you even deeper into other bonus features. In addition to the bonus feature, there is a wild symbol which multiplies your payout.
