In Matter Tangram you'll be using your knowledge of geometry, trigonometry, and shape recognition to decipher the puzzles and create the shapes given to you on the left hand side of the screen. You'll use a smattering of what seems like random pieces and shapes in order to make one solid shape. This will be pretty tricky and may take some time. You'll be scored based on time and how often you move the pieces. You can allow cheats if you want but of course the diminishes your score. This is a super brain teasing game that will keep you playing for hours.
