Mars Odyssey is a very interesting video slot game from SkillOnNet with a sci-fi theme. You get a glimpse of how Martians look like in this game. there are aliens with all shapes and colors and the game play is interesting but when I played this slot I lost all my money very fast.

This is a 5 reels and 20 pay lines video slot game. I always place a bet on all pay lines no matter if they are fixed or not. I know that this way I have a greater chance to land a win. I was playing this slot on min bet 0.20 per spin. I do not know for what reason I could not win anything during the game play. The highest win that I got was for 4 red alien symbols with the glasses, or eyes in the shape of heart, and the win was 1000 coins. I even once land 5 green aliens with the orange heart and I got so excited but when I saw the win 50 coins I knew that this is one of the weakest symbols in this game.


There is only one special feature in this game and that is the free spins round. This game is not triggered with scatters but it is like in every other SkillOnNet game where you have to collect 1000 points to trigger the feature. You get 50 points every time there is a bonus symbol on the reels. When you collect 1000 points you get 10 free spins. I could not trigger this feature, and I did spend a lot of time playing this slot. Simply I was not lucky enough to land the bonus symbols on the reels. But I doubt that the potential is very high in this slot. I would not recommend this game to anyone, because simply the payouts are so poor no other reason.
