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.

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?
