Gravity Grid is a challenging online puzzle game where you have to match up sets of 3 colored blocks by flipping or rotating a chess board-style grid. In each level, there are jumbled-up groups of 3 colored blocks on a square game grid. You have to use your knowledge of gravity to figure out the correct way to flip the grid so that the colors match up. The problem is, you only have a certain number of moves to do this.

The grid can be moved 90 degrees to the left or right, or flipped upside-down 180 degrees. You have to choose the correct move that will connect the same-colored blocks together. Once you have all three of the same blocks touching each other horizontally or vertically, they disappear and you can progress. The levels increase in difficulty, with more groups of colored blocks being introduced.

This problem-solving activity will really test and exercise both your observational and logical thinking skills. You’ll also need to display good strategic planning abilities to figure out a solution to match up the different colors. Think you’ve got the eye and mind to master this tricky brain-teaser? Ok then Gravity Genius, bring it on!

How to Play: There are 30 levels that increase in difficulty as you progress. At the start of each level, you have a square grid with different groups of colored blocks on it. There are always 3 blocks of each color. In early levels, there might be only one group of colors, but more are introduced as you progress. You must connect up these colored blocks by flipping and rotating the grid. You have 3 options – Rotate the grid to the left, Rotate it to the right, or Flip it 180 degrees. Left Click on your computer mouse to choose these options at the bottom of the game screen.

Each time you move the game grid, the colored blocks move too. You need to move them into a position where all 3 of the same color are connected horizontally, vertically, or in an L shape. Once all three blocks are matching, they disappear. Match all the groups of colors on each level to progress. Don’t forget, you only have a stated number of flips / rotations in each level. You can see how many moves you have remaining along the left hand side of the game screen. If you run out of moves, you have to start the level all over again. Let’s get matching!

If you want to create your own levels – try the Level Editor Mode. Here, you can design your own levels and make them as easy, or as difficult, as you like. Once you design a level, copy the code and paste it into the Level Loader Mode to test it out. Happy puzzle creating!
