Machinarium

There are only 2 playable console games, the third one breaks when you try to charge it up.

That first machine is Space Invaders where you need 1000 points to win. You get points by shooting aliens, and you can get bonus points for shooting the big UFO that travels along the top of the screen periodically.

Remember to play this game several times over for the SHARPSHOOTER achievement for shooting 500 Aliens. I got it at the beginning of my fourth play.

The second machine is a tricky puzzle game where you must fit a small red box inside a bigger one to open the exit.

See the screenshot from the Walkthrough for the given in game solution:

Note the first move in each picture is always the one with the line that actually connects to the player block.
