It's backwards day on Mobile Monday! Instead of telling you about portable gaming's goings on, we're going to analyze historical examples of decidedly non-portable games. Did you know that Stonehenge is actually a massive in-progress game of tic-tac-toe? Or that the pyramids are the only remaining pieces of a game of chess? Your move, gargantuan space aliens.

Oddball does something odd - Here's a bit of reverse mobile news: the formerly mobile-exclusive physics game King Oddball by 10tons has gone and spawned a downloadable version of itself! Feels backwards, right? Either way, it's more destruction and more of the weirdo king and his cantaloupe head. King Oddball is so mad that he's flinging rocks with his tongue and trying to take over the Earth. The forces of humankind aren't going to sit back and watch, so the Earthlings send in the military, occupying squares of terrain that the King gradually moves through one conquered space at a time.

Dr. Stanley does house calls - If the recent avalanche of mobile escape games hasn't satisfied your puzzle solving needs, let a classic browser game do the trick! Both of James Li's Dr. Stanley's House games have made their way to Android and iOS, and they're just as good as they were when they first hit a few years ago. The touch screen controls couldn't be smoother, either. We're so cool we've even got walkthroughs for both games. Go ahead, consult them when you get stuck. We won't tell.

I wanna be an astronaut! - Need to squeeze in your astronaut training but are on a budget? Jorge Hernandez, creator of the phenomenal Astronaut Spacewalk, has released a free training simulator to help you figure out what the heck is going on in this insanely detailed game. Astronaut Training sticks you in the Neutral Buoyancy Lab swimming pool so you can learn to use the Manned Maneuvering Unit with something resembling skill. It's a good introduction to the physics and detailed control mechanisms in the full game, but like the marketplace page warns you, it's EXTREMELY difficult. We like that in our space games!
