Flex your mind with this retro-themed puzzler!!!

***One of Today's Best Apps (Feb 21st) - ***

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 that
1) the light from each of the laser sources ends up at it's correct destination, and
2) 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.

Great Game, but it has some bugs


I was looking for the game Black Box and found this game instead. It's similar to Black Box in that there is no chance to it, it's all logic and reasoning, but it has more aspects to it. I find that exciting!

The game has many boards in multiple levels so that it will keep you engaged, no matter what your skill level is, and will continue to challenge you has your skills increase.

Good game but buggy


I really enjoy the puzzles in this game. Levels get gradually more challenging and it's somewhat addictive! I just wish I could actually play it! Every time I accidentally hit one of the stupid ads, the game locks up and I have to uninstall and reinstall it. Again the puzzles are great, but it's extremely disheartening to get half way through the advanced levels and gave to start from scratch.

If this bug gets fixed, I'd give this 5 stars. Until then, it get 2.

Good for all levels of play


I like the game and the levels of difficulty available as does my grandson. His perceptions are improving each time he plays as are mine.
