This update still utilizes the same slick interface and near-flawless gameplay mechanics as before to create a serious action-puzzle challenge. If you didn't play Contour when it was first released, there's never been a better time to give it a spin. Since then, the community embraced the editor and set to work creating new levels. In fact, so many new levels were created that Sean hand-picked some of the best and updated the game.

The original Shift was an interesting platform game that used negative space as an entertaining hook, but it came with a few problems that ultimately made it feel unfinished and experimental. Now, Tony of Armor Games has released Shift 2, which is basically the game the first one should have been. It's not enough of a leap forward to warrant the "2" in its name, really, but it refines and expands upon the original concepts to deliver a smoother, more drinkable dose of run/jump/puzzle distraction.

Why play a game of dominoes when you can line them up and watch them knock each other down? Developer Tom Methven may have been in that exact frame of mind when he created the puzzle game Sky Blocs, the lovechild of youthful domino play and The Incredible Machine. Each level presents you with a starting block (bloc?) and an inventory of pieces to the left-hand side of the screen.

In Angular Momentum players are plunged into what looks like a futuristic ant farm and must guide the requisite ball through a series of chambers to the exit. The levels boast twisty, up and down landscapes worthy of Sonic the Hedgehog; tools such as speed boosts and jump platforms will help you reach the exits, but beware of the eeeevil orange panels that will send you back to the start.

Every time we review a picross game, there always seems to be a hubbub about what site does it right. Either there's not enough puzzles to solve, not enough variety in the puzzles, it's all too easy or too hard, or the pictures look like someone sneezed on a piece of graph paper. (I'll admit to being among the gripers before.) And every time, there's at least one person who suggests Griddlers.

Remember Line Rider? That was a pretty sweet webtoy made by a guy from Slovenia. But did you ever get the feeling that Line Rider could have been so much more amazing if there was more of a game to it? Fresh off the CandyStand, we have Line Golfer. It's like Line Rider, but you can golf your way through the mouse-drawn levels instead of watch a character sled through them. Frankly, it's money.

Contour is a clever re-imagining of Marble Madness by Sean Hawkes, creator of several games entered into previous competitions such as Orbit and Clack. An isometric grid is placed over the playing field that holds a ball and a white exit square. Click on individual tiles to raise the ground from that point, causing the marble to roll downhill. The goal is to move the marble to the exit tile by raising and lowering the floor, a feat that requires both intelligent planning and fast clicking.

Free Rider 2 is a sequel that continues the more interactive spin on the Line Rider formula. Using a large tool set you can sculpt, edit and decorate the environment any way you choose. When you're done, take to the arrow keys and drive your rider through the stage. It's webtoy-meets-level-editor kind of experience, and it's even better than the original.

From the award-winning Preloaded design team comes a new physics-based game designed for the Science Museum in London. Launchball is a fabulously produced take on the 'guide something to the goal' family of physics games. There is even a level editor with which to create puzzles and send them to your friends.

The next entry is from Damir Srpèiè of Slovenia. You might remember Damir from our first competition with his popular and creative entry, Personal Universe. Roped! implements "ball physics" as well as 'rope physics' in this unique puzzle game that also includes and integrated level editor and save feature.

Blackflip is a remarkably well-produced puzzle game inspired by the game Polarium for the Nintendo DS. It's a very simple game to understand, and yet quite challenging to play. The best part about Blackflip is that all of the puzzles are created by other players, and you can even link to specific ones you create by using the tags provided.

The main focus of Knytt Stories is atmosphere, environment and exploration, not complex gameplay and a barrage of media. With Knytt Stories you'll spend most of your time wandering around sparsely populated worlds looking for a few rare items, enjoying the beautiful visuals and ambient music the whole time. It's a unique experience in gaming and will pull you in from the moment you start playing.

Zeta Flow is a Flash-based shmup in which you control an innocent little turret gun ship as you fight off giant mechanical enemies. Each level pits you against one evil ship, getting progressively bigger and badder from level to level. It's a fun game that plays great, and there's even a level editor, too!

Puzzle fans rejoice! A sequel to the critically acclaimed action puzzler, Professor Fizzwizzle, is here and it's HOT! Just released by Grubby games, Professor Fizzwizzle and the Molten Mystery picks up where the first game leaves off and presents over 200 fresh new levels to sink your puzzle-loving teeth into.

The old "navigate through a maze" concept enjoys a small rebirth in the form of Overhead Persistence, a gorgeous Flash game by Acrid Rose. Guide the cursor through each level avoiding the walls and any other obstacles you come across. Normally a game like this wouldn't be anything special, but Overhead Persistence provides a stunning audio and visual package along with a level editor and other extras to make a worthwhile experience.

Free Rider is a brand new take on the massively popular Line Rider, which you voted best web toy of 2006. Pete adds several interactive elements to the mix that actually serve to create an entirely different experience. It's more like Line Rider meets Teagames' BMX series, the result of which is a create-your-own-level style of game.

Block Quest, the sequel to Block Action, is a free online platformer game with hundreds of user-created levels to play. Run, climb and wall jump your way through the surprisingly deep variety of stages of varying difficulty and creativity. It's a very simple game idea that has turned to gold in the hands of its users.

Capsules is a simple game where you must maneuver an orange shape around red obstacles in order to reach blue spheres throughout the stage. The levels are remarkably unique and bend the formula in every possible way. You can even create your own levels with the included editor!

Deadly Rooms of Death is a turn-based puzzle game; one turn being the amount of time it takes Beethro, the central character, to move one square or to swing his sword by 45 degrees. DROD is very much a puzzle game, but unlike any other you may have played before. It is actually the sequel to the critically acclaimed DROD: King Dugan's Dungeon, and both were created by Caravel Games.

Rubicon is an amazing machine-building puzzle game, level editor, and sandbox toy. Gameplay consists of moving crates to one or more targets for each level. Each crate must come to rest on its corresponding target for a green light to appear. Use the component materials provided to construct any machine that will succeed at the task.

Another brilliantly intricate and well-designed puzzle game from Rob Allen, this one with similarities to classics Rogue and Lode Runner.

Complete with level editor to create your own level designs!

There is more than one way to enjoy this simple but effective Flash platform game construction set.

Brain Strainer is a physics-based construction kit with which the player creates a quasi-perpetual machine from a palette of objects including bumpers, kickers, conveyor belts and other contraptions. The objective is to score enough points to launch a rocket.

JP of Pepere.org recently released a new version of his Ringmania game, creatively called Ringmania 2. In this latest update to the connect-three game based on magnetism, control is now with the mouse allowing more freedom of movement as you try to eliminate all of the colored rings from each level's initial configuration.

Armadillo Run is a physics-based puzzle/building game for Windows. Your job is to create structures to safely guide a rolled-up Armadillo to the goal. Assemble materials such as sheets of metal, ropes, cloth, elastic and more to create a path across the stage. The physics in Armadillo Run are remarkably accurate, making building (and destroying) things far more entertaining than it should be.

Eets is an amazingly addictive action/puzzle game from Klei Entertainment.

Slot-car racing fun in this Shockwave game from Sweden. Build your own course then race against the computer, or against a friend using the same keyboard. The game physics and sound effects inject just enough realism to the game to make it a lot of fun, and the AI is brutally hard to beat at higher levels.
