Did you think you had truly escaped The Dark Room? HA! Commandingly Deep-Voiced Australian John Robertson is back to taunt you a second time, as you try to escape The Dark Room: Round 2, a continuation of his darkly-comedic YouTube puzzle adventure. Things are a little darker and a little angrier this time around, but the concept remains as hilarious as ever.

You can't look around. You can't check your inventory. You can try weeping, but expect Australian comedian John Robertson to taunt you if you do. ("Is there anything as sad as tears only you can feel but nobody can see?") If you're going to escape from this YouTube-based puzzler, you'll need to think outside the box. Actually, that won't help you either. You're not in a box. You're in the Dark Room.

And yes, you know it's your destiny to try and cache 'em all!

PMOG aims to capture the social dynamic of an MMORPG while remaining accessible to your everyday Joe Gamer. However, it wouldn't be much fun if you could just up and create a top-level character – there has to be some sort of dirty work, some progression by which you earn your stripes. This is the part of the game that usually keeps MMORPGs from staying casual. PMOG solves this problem by tying the leveling process directly to your web surfing.

The N riddle game is a URL-changing puzzle game that is somewhere in-between a wonderful, mentally stimulating journey and a migraine in the making.

If you're a regular visitor here, then you probably love casual games and puzzles as much as we do. Most of the games featured here are browser-based, but once or twice we've featured a puzzle or two that require the old-fashioned method of pencil and paper.

Well, they have just published a new one, and this one will surely give your brain a tickle.

An online puzzle game in the same vein as God Tower, Dumb: The Game and Not Pr0n. These lateral thinking Web games are the work of one apparently psychotic mind, Mark Lautman. In the first 16 puzzles alone, you'll come across binary code, a crossword puzzle, a word scramble, and a quote from... nevermind, that would give the answer away. What they lack in polish they more than make up in deviousness.

Those of you who enjoy a stripped-down text adventure game and don't mind a bit of repetition will get a bit of fun out of these DHTML-based Enchanted Forest games. The point is to get as much gold as you can. For such a simple game it's surprisingly addictive, but don't worry—if you're a true casual gamer, you can leave your game at any time and when you return, it will be waiting exactly as you left it.

And for those who enjoy a good challenge, they claim that this logic puzzle was written by Albert Einstein himself, and that 98% of the people in the world could not figure it out. Which percentage are you in?
