Flex your mind with this retro-themed puzzler!!!***One of Today's Best Apps (Feb 21st) - appslooking.com ***Photon Lab is a beautiful and satisfying light-bending puzzle game for all ages that will shake up your neurons as you try to figure out the convoluted path to success.The aim is to drag the moveable mirrors into squares on a grid so that1) the light from each of the laser sources ends up at it's correct destination, and2) some light passes through every square on the grid.It is very simple to play and understand, but the challenges go from easy to very hard, depending on the size of the grid and the number of moveable mirrors.There are 480 puzzles, and some are easy, while others are deceptive and you might find yourself thinking they are impossible until you get that "ah-ha" moment.There is also a "Speed" mode, where you have to solve five puzzles in a row as fast as you can.And if you like an extra challenge, there are 21 challenges for you to complete.If you want a helping hand now and then, you start off with 5 hints available, and can upgrade to get unlimited hints.So come on in - hours of light-bending, mind-stretching, puzzling fun await you at the Photon Lab.
