A free slots game like no other, we think this is the best free game around. Win Big!
Astro Invaders is a new Vegas style casino game that unwraps around you as you play.

Notching up the big wins also gains you experience points (xp), which will eventually allow you to "Rank Up" and win even more. Ranking up reveals new game features, free slots, bonus minigames, bigger wins, etc., so there's always something new to aim for as you pump in those free coins.
Main Features:
• 48 Rank Ups, providing 48 gameplay expansions as you progress.
• Many scatter symbols for lots of bonus rounds.
• Generous amount of wildcards leads to plenty of big combo payouts.
• Up to 25 paylines for big jackpots and combo wins.
• Minigames add skill and variety.
• 100 collectable prizes to, er, collect.
• Drop special symbols on the center position to start "Invasion" and "Rocket Attack" bonuses.
• Achievements and Leaderboards to show off to your friends.
• Variable bets and auto spin.
• Complete lack of cheese. No horseshoes, lucky 7's, crock o gold or green dwarves anywhere. Lots of free slots.

(This game is kept free thanks to occasional advertising. If you prefer, a small in-app purchase can be made to permanently remove them and score extra spins into the bargain.)

Disclaimer:
No leprechauns were hurt in the making of this game, but a lot of shamrocks did get trampled. Slots still as free as ever.
