What is it?
Lightup is a puzzle game played with beams of light. The premise is simple; reflect the light beams to light up the “LEDs” of the same color. Once all of the LEDs are lighted, the round is complete.
The background is a bit reminiscent of the old Tempest or Tron arcade games. The game board is a grid set on a background which looks like stars viewed from deep space. The light sources and tools used to manipulate them are simple line drawings.
Given the nature of the game, the simplicity is fitting. If there is any drama in the game, it comes from two sources. First, the rounds are timed against a “par” time. Second, there may be a “black hole” that will accelerate the round timer if a light beam hits it.
How does it work?
There are a handful of devices to alter the light beams: mirrors, splitters, mixers, etc. To use a tool, simply tap and drag it to where you want it. From here, you can tap the device to rotate it until it is facing the desired direction. You are allowed a certain number of tools each round, and you have to figure out how to arrange them to light up all of the LEDs. There is pretty much only one way to arrange things to complete the round (I don’t know if it was intentional, but I solved one round with one tool less than what was provided).
The game provides a little twist every five levels; the lights are turned off until you hit a switch. You can test your arrangement, but if it is wrong you get an ERROR and all of the tools are removed from the playing field and the timer keeps running.
Is it contagious?
If you like puzzle games, this one is fairly cool. It’s a bit like playing billiards with laser pointers and mirrors (and who doesn’t like playing with lasers?). The color combinations and splits are correct and useful even early in the game. There are 48 levels, so there is enough playtime for a few hours. You can replay a round to improve your time and your score.
