In the game Hyper Trigon Party, you will go to a three-dimensional world and will help various geometric shapes survive. You will see a triangle in the center of the screen. It will consist of several parts of various colors. Solid lines having a certain color will fall on top of the subject. By clicking on the screen you can rotate the given object in space. You will need to substitute a part of an object of the exact same color as the line itself. Then the line will pass through it and not cause harm.
