The first 99 Bricks stuffed the standard Tetris formula full of physics, and now the sequel has crammed a whole bunch of RPG elements in there. How many genres can Tetris possibly hold? With your help, the vigilant Garry must save the kingdom of Brickonia from dire peril, and that means you need to build a whole lotta towers out of tetrimino blocks. Weird like a beard, man.

The title sounds like the name of a top-secret Cold War superweapon, or perhaps a very specialized brand of bleach, but Red Remover has nothing to do with either Soviets or stains. Instead, this latest offering from Gaz charges you with the task of removing all of the melancholy red blocks in a level while keeping all the exuberant greens.

In Crane Wars, you play the role of a crane operator, and your mission is to grab hunks of building and stack them on top of each other. Your other, more fun mission is to fling stuff at those filthy scabs working next door!

Redstar Fall is back, with 20 more levels of physics puzzle mayhem. Blast away the tower of bricks one by one, to bring the red star to rest on solid ground. These new "Pro" levels are tough and finicky as a dried-up alley cat, so practice up on the first game before you tackle them.

Redstar Fall is a short but wonderfully executed and atmospheric entry in the physics-based stacking/unstacking genre. you begin each level with a pile of oddly-shaped blocks sitting on an island floating in the sky. Click on a block and it vanishes, allowing everything above to shift with the pull of gravity. Your goal is to ease the red star down so it comes to rest on the island.

Have you been wandering around in a haze since the first Perfect Balance, your heart crying out for the opportunity to wedge more things together? Do you miss the wedging like a starving shark misses bluefish? Then Perfect Balance: New Trials is here to offer you sweet, sweet, soul-crushing relief, in the form of 30 more levels of tough block stacking.

Following the success of the first game in the series, Totem Destroyer 2 is bigger and better. In each level you must bomb all of the destructible blocks, without allowing the golden idol(s) to touch the ground. It's a beautifully executed follow-up to the excellent original, and it should not be missed. There's way more levels, new types of blocks, new types of idols, and even a level editor!

As any guy with a bottle of super glue and his ex-girlfriend's CD collection can tell you, it's fun to stack things on top of each other. So here's the deal: Super Stacker 2 offers 40 levels of shape stacking, ranging from pathetically easy to hand-crampingly difficult. If that's not enough, I have three very special words for you: Level. Editor. Booya.

Perfect Balance is an 80-level brick-stacking puzzle game that asks you to… wait for it… balance a collection of shapes… wait for it… perfectly on a tiny jutting spire, or maybe a slanted line, or a sprinkle of floating cubes. You'll enjoy how the puzzles ask you to understand different properties of physics, including friction and inertia. Solve two realms worth of challenges: "Harmony" and "Inferno".

Your goal is to build stacks of animals as high as you can. Combine identical animals along with their favorite food and they begin to breed, multiplying their number and pushing your totem even higher. Each animal interacts differently with others, so learning their relationships is key to creating massive stacks of animals.

In a twist on the classic block stacking game, 99 Bricks challenges you to make a brick tower using standard Tetris play mechanics. The twist is that as the tetrominoes fall and stack, they don't disappear when lines form. This time, your goal is to make the tallest tower that you can. A higher tower means a higher spot on the leader board.

Totem Destroyer is, to say the least, an ironic name for this little jewel of a puzzler, considering that the very last thing you want to do is destroy the totem. The goal of each level is to instead retrieve the tiny golden little idol unharmed. Keeping you from your prize is the precariously stacked structure upon which its perched. Your goal is to selectively destroy the required number of blocks for each stage without letting the totem touch the ground.

Deluxe features an amped-up, graphically-superior 3D presentation to the original mobile title with more complexity and improved game mechanics. Watch the swinging block and tap the spacebar to drop it. Line the blocks up and watch how high the tower can grow!

Killawatt is a game about stacking speakers onto a truck with a wobbly, aerial crane. It's the latest addition to Samsung's arcade of surprisingly solid advergames, featuring Sammy, a conspicuously anglo, canine mascot. This time, however, Sammy has his black snoopy ears in a dreadlock-esque style, and he's gone rasta.

It's SimCity meets isometric Tetris in this new casual mash-up from Electronic Arts, The Sims Carnival SnapCity. As mayor its your job to build a thriving city and keep its citizens happy and prosperous. Three colors of blocks descend onto the grid, each one representing residential, commercial or industrial zones. When the blocks land and are connected by roads, citizens begin to move in and your population grows. Extras like puzzle zones and natural disasters keep the action lively, but it doesn't take much more than that to keep you hooked on this addictive game.

As the name suggests, Balancing Act requires you to keep a number of balls (and other ball-ish things) balanced on top of each other. Click on a ball and drag your mouse to rotate it, but remember that each action has an equal and opposite reaction! The stylish and humorous presentation and simple control system are to be particularly commended in this worthy game design competition finalist.

Tower Bloxx is a captivating action/puzzle game originally created for mobile phones. Using the mouse button you must drop pieces of a skyscraper from a swinging crane at the top of the screen. Stack the blocks neatly or you'll be in for a tough time as the building reaches toward the sky and sways in the wind. A quest mode lets you build an entire city one building at a time and also adds a little strategy to appease the more hardcore gamer in you. It's a near-perfect blend of casual and serious gaming that everyone will enjoy.

At first glance, it appears to be a Towers of Hanoi puzzle, and maybe that is why I did not play this game the first time it crossed my path. Not because I view Towers of Hanoi unworthy, for it's a classic puzzle game and one that is often used to teach recursive algorithms in programming. I passed on it because I thought it was unoriginal.

Just click on blocks to move them into the target configuration for each of the 20 unique levels. Award-winning Stackopolis is not only an enjoyable game to play, it also features gorgeous pixel graphics and animations, and a delightfully dramatic soundtrack that pushes this game over the top into highly addictive territory. You've been forewarned.

The tree of Vanilla grows rapidly and becomes difficult to manage and balance if not cared for properly. Like the tree it's named after, Vanilla is a deliciously refreshing and original game from Eyezmaze that is simple to pick-up and play, but difficult to beat. The objective is to see how high you can make the tree grow before it tips too far towards either edge of the play field.
