Anyone that has been visiting this site for a couple of years will likely remember the amazingly popular Hyperframe from 2005, a 3D logic puzzle of connecting same-colored blocks on a 3D cube with unbroken non-intersecting lines. There is a new version of a clone now available, appropriately titled 3D Logic 2, and it's just as well done and addictive as the original Hyperframe was.

Bloxorz is a simple idea for a puzzle game that is beautifully executed. The objective is to tumble a rectangular block through each stage and deposit it into the square hole at the end.

We see clones of classic casual games everywhere—games with blocks that fall and lines that clear. But the ones that really shine through are those that build on a classic formula and make something new out of it. Chain Factor is one of the those games. While the game may seem intimidating at first, with its grid of all sorts of numbers and the occasional boulder, it is actually deceptively simple.

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.

In Gateway 2 you again guide a robot, through a dream-like setting, in order to solve numerous and varied mini-puzzles for a seemingly unknown purpose (though a purpose there is, as you soon discover). Using well-placed musical cues and subtle environmental sound the author has created a virtual world that draws you in from the moment you launch the game. The setting and aesthetics are so enticing and mysterious, it doesn't matter at first that you don't know what your ultimate goal is (or indeed if you have one).

Gravity Pods is a physics-based vector shooting/puzzle title created by Wicked Pissah Games. The goal is to fire a projectile and hit a target across the screen.

How you go about doing that is different for every stage. The task is up to you to figure out how. Just right to get those brain cells jumping with inspiration and excitement on a Monday.

Sometimes you run across a new game that feels exactly like a classic—like it's been around for years. The mechanism behind Michael Le's Jelly Blocks is so simple, so intuitive, and yet so versatile that it's a wonder that nobody has come up with anything quite like it before. In short, it bears all of the hallmarks of a great classic puzzler.

From the award-winning Preloaded design team comes a new physics-based game designed for the Science Museum in London.

A new stylish title from Game Pure has just been released: Micro Art. The hybrid puzzle combines elements of SameGame and your classic match-3 game with a unique line-drawing mechanism.

Draw a line and collect the floating pieces to make matches and keep the stack from reaching the top of the screen.

It really is amazing to see such creativity sprout from a simple word, as with the recent competition and its "grow" theme.

In this 18-level game, there are only but a few rules that you need to know to get started.

ReMaze starts off easily enough, with only one corridor down which to guide the white squares. Then there is another, and another, and soon you are caught up trying to navigate several mazes at once, not just to reach the goals, but to reach them simultaneously. Then comes the red death. One misstep and you're toast!
