Puzzle and Skill Games
These are the games that require an amount of logic and quick thinking, used towards finding a goal in each phase.
The Assembler series 
The Assembler series is an extraordinary title that I found this last month. It is another game that uses hand-physics, and a game where you must use those self-same physics to your advantage, stacking the shapes so that the green shape fits neatly in the slot meant for it. There is also buoyancy in underwater stacking that must be considered, as well as the weight of the shapes being stacked. A really incredible title that won me over with it's most addicting gameplay, so I'm giving it no less than 5 out of 5.
Two Rooms 
In this logic twister, you have two robotic boxes in seperate rooms. You can generally only move one at a time, and in one of the rooms will be a checkered goal zone. To move on to the next level, get the box in that room into the goal zone. These are often are obscured by gates, which you can retract by stepping on the same color switch in that room. The problem is , oftentimes the gate will retract only to close off the path in the other room. Some switches are concealed in crates, which you can only break by sliding into the space between a wall and a closing gate, like a trash compactor. Then there are also teleporting panels, and power-ups which can reduce you in size and make both boxes move at once. A great game, really. It might sound confusing at first, but each level introduces a new item and how to use it, so you understand it after a while. With 30 levels, it will keep you entertained for a while. 4 out of 5.
Chronotron 
In Chronotron, you help the cute robot dude repair his broken time machine, so he can travel back to his time. The inginuitive gameplay involved here is great, because you use past versions of yourself to open switches, pick up platforms, and act as weights. but if you don't be careful, you can end up killing or trapping a past version of yourself, resulting in a paradox, which sends you back to the beginning of a stage with a warning. something like, "Please be more careful not to bend the laws of physics again." I think. I can't remember. Anyway, great game, but becasue of it's confined nature in one small-ish room, I'm only giving it 3.5 out of 5. -Play-
Splitter 
In this wood-splitting title, you must guide the very eager smiley face to the exit portal by cutting the wooden blocks that it it perched on, as well as the chains that they dangle from. Brick walls under no circumstances can be moved or cut, but while gray blocks cannot be cut either, they can easily move or rotate on chains. This physics -involved game is fun not just because of it's fresh gameplay, but also because of the way it makes you think to solve the puzzles. If you do not cut the blocks at just the right angle, then it may work, but in a different way than presumed. You also generally have a limited amount of cuts to use. It's definitely worth the effort to play, so check it out. 4.5 out of 5.
Super Stacker 
This is a great, great, game. The main goaol of both Super Stacker and the second Super Stacker is to balance the shapes given on the base given. Both can be anywhere from miniscule to gigantic, and all bear either terrified or bright and happy faces, depending on how you're doing. There are a grand total of 40 levels in the newest version. And if you're wondering why I've only given a link to the second one, it's because I came to that conclusion after considering the fact that all the levels from the original one can be found in the second one. Anyways, when you're not trying desperately to correct your mistakes through unbalance, you are unpatiently waiting for karma to strike down your tower. It's a really great game that easily earns a 4.5 out of 5. -Play-
Portal: The Flash Version 
In the popular game Portal, your goal was to use the Portal gun to solve mysterious rooms and puzzling chambers, and unravel the path to get to the door on the other side. In this flash version, your mission is much the same, only now it is 2-D. It's actually very fun, because like Epsilon, when you jump in one you pop out the other with equal force. Only in Portal, if you fall from too high or too fast, you die, and the gravity remains the same. I enjoyed it a lot, because it was beyond what you would think normal puzzle games, with an innovative gameplay that the original was well-known for. 4 out of 5. -Play-
Epsilon 
Epsilon is a research facility that expiremints with time travel and space. you are it's prime testing participant. Two portals can be clicked and dragged around the edges of the screen, and when the probe goes in one it pop out of the other with equal force. Use Gravity and Time to collect all the glowing balls and get back to the portal before the time runs out, and bend the laws of physics to your needs. This was an extraordinarily fantastic creation, and I give it a hearty 4.5 out of 5. -Play-
Shift 1, 2, and 3 
Shift is a unique puzzle game that allows you to "flip" the stage, so that what was black is white, and vice-versa. This is called "Shifting", and you use it with the Shift key. The key platforms cannot be shifted on, but rotate to cover spikes or create platforms if you collect the floating keys. In Shift 2 you can make you're own Shift puzzles. Shift 3 offers a more advanced storyline with an auto-save feature, and also includes the level editor. This is a fun and challenging game series that I think deserves a 4 out of 5.
DUI 
Now in the world of internet, you'd think this is a somewhat stupid game having to do with drunk driving. Well it's not, and it's a really fun game as far as I'm concerned. The object of the game is to remove a number of blocks (and by remove I mean make disappear completely) from a structure. Sounds simple, right? But the trick is you have to do this and leave the sprites (little shapes with faces that you can move balancing atop the teetering structure.) above the red line that goes across the screen. There are 36 levels of this madness, so I suggest you get busy. 5 out of 5. -Play-
Music Bounce 
In this game you must shoot balls from the slots in the side of the screen to hit the colored blocks. When they are hit, they will make a percussion sound or a note, then disappear. The darker colored blocks take two hits to vanish. All the blocks will come back once a full 8 beats have gone by, and when a ball hits one block it will bounce off of it. Create paths of motion and music to solve the puzzles, and use the beat to your advantage. This is a great game with a 5 out of 5. -Play-
Light Bot 
This little robot looks cute. Maybe it's the little light on his head. I dunno. Anyway, in this game you have to program this little guy to jump, move, twist and otherwise navigate the level. The main object is to create a programming (you only have a limited amount of memory) that gets him to move over all the blue tiles and light them up. I got really confused at the start, but as it explains it, I got more into it. Fun with a 4 out of 5. -Play-
Rocket Man 
This is actually kind of funny. You are a cartoon guy with a rocket launcher (great combination, that is) that must guide your ammunition to blow up a guy on the other side of the screen. You must navigate through the caves and turning stones before your rocket runs out of fuel, and explodes into fthin air. Make it through quick and safe, or you'll run out of rockets...it's highly entertaining and fun to play to, so I think it deserves a 4 out of 5. -Play-
Angular Momentum 
In this game you must speed the ball to the exit using boost pads, jump pads, moving platforms, zero gravity, and more. If you touch the grounded reset generator panels, or the moving reset balls in the air, you will begin back at the entry tube. Control the ball using the arrow keys, and propel through these dizzying levels. 4 out of 5. -Play-
Animals Underground, Below, and Above 
So in the first, you are a cannibal Ostrich that likes Eggs. So where do you look for them? Underground, of course! But moles with scythes don't like you disturbing them in their little underground chambers, and will make every attemt to cut your neck off. Jump into the sewage pipes to save your neck (literally)! The second is about an elephant that escaped the circus so it could eat oysters (?) and live a happy life of snorkeling. He discovers that Elephant-eating fish don't like Elephants who like oysters. Fortunately there are trunk sized shells that make your trunk come out of another shell. Stretch, elephant, stretch! And finally the third is about an apple-crazy giraffe on a voyage to eat every apple in Africa, with a gang of monkeys on his bad side. They just bite you to annoy you, that's all. This series provides a large amount of fun puzzles, so try it out! 4 out of 5. -Play Ostrich- -Play Elephant- -Play Giraffe-
Magigoo 
In this game you are something resembling a dwarf in what appears to be a pen filled with globby creatures called goos. You must capture them by drawing a circle around them with your mouse, which the dwarf will follow. Some of them move making them harder to capture. When they are captured they disappear, leaving behind various items that will help you banish more goos. That's pretty much it. I'm going to give this game a 4 out of 5. -Play-
Soap Bubble 1 and 2 
In these games, you are a lone Soap Bubble that explodes at the slightest contact with any object. In the second one, there is more of a storyline involved, and you find friends among the similiarly-traited warheads in a warhead factory, right? Wrong! So you have to navigate your way through the dangerous corridors as your Soap Bubble starts to recognize what it got itself into. In each level there is a code in the corner of the screen, that if you type in on the menu, it will take you directly to that level. I give this game another 5 out of 5. I enjoyed it much. -Play 1- -Play 2-
