Crossing 3D is an entertaining puzzle game for all ages very similar to Tetris, in this game you have to eliminate from the board only those blocks, which have the same color on cross lines (horizontal and vertical). To eliminate the blocks you have to click with the left button of your mouse on them and new blocks will fall from above. You get points for all the blocks you eliminate from the board and you get to the next level when you reach a certain amount of points. The game features decent but not impressive graphics, some good effects and repetitive music. However, as it is very customizable you can adjust it to your system requirements and tastes. In the trial version you can only select the difficulty level and other common options, but the complete version includes different game modes. You can play in full screen or windowed mode, choose any resolution, select the video adapters for your computer, and quality of the graphics. You can save your game whenever you want and continue it later. All in all, Crossing 3D is an enjoyable game that will keep you playing for hours and hours non-stop.
