# Four piece tangram

Do not look down upon this ancient puzzle game - it may be much more complicated than you have imagined! Your task is to make use of the 4 tiles provided to form the required shapes. At each stage you will be given 4 pieces of tiles on the right of the screen, while the outline of the required shape is on the left. Click and drag the center of a tile and move it to a desired position, and you may rotate the tile by dragging it around the center, or flip the piece by dragging through the center. Note that the tiles on the shape cannot overlap and no space is allowed between them. A timer above the play area will count the time you have spent at each stage. Solve the geometric puzzles by lateral thinking!
