Best and most addicting free games on Droid are:
Abduction! - Platform jumping game. Very addicting, especially when you are competitive for high scores. Try "Evil Infinite" difficulty!
Andoku - A Sodoku game. Simple and pleasing to the eye. Great UI.
Antigen - a unique Action/Puzzle game.
Bonsai Blast - Similar to Zuma. Very addicting.
Cestos - (This is a multiplayer game only) Shoot your balls at your enemy's balls - knock their balls off the table (or keep your balls on the table) to win. Har har... balls. Plus, you get a very interesting chatroom lobby, too. Find me, Bobtheevilbeing.
Sketch Online (BETA) - (This is a multiplayer game only) Pictionary-style game where, in a chatroom, a randomly chosen player is given a word by the server. That player begins drawing on his/her screen. Other players guess what the drawing is of. Very fun, and definitely addicting. Score is kept.
Sketch Wars - The MOST addicting game on Droid. I'm going to describe this one a bit more indepth because you NEED to try this little gem out right now! This game is in the style of Asteroids and it is the closest clone to Geometry Wars I've seen yet. If you don't know what Geometry Wars is, you're in for a treat. Go check this one out. Free version (medium difficulty only). Buy it for a dollar or so and you get 4 difficulty options!The only problem with the game is you have to use the touchscreen to direct your fire... covering the enemies sometimes. It takes a little getting used to, but I don't find it a problem any more. Try to beat my high scores! The game uses Scoreloop to track high scores. I'm Floridadre2000 on Scoreloop.
I hope this helps out those of you either having trouble finding or are too lazy to go try out crappy games to find the good ones! Happy gaming!
