Power Light is a logic-puzzle game that's similar to water pipe logic-puzzle games. Across levels on a 5x5 playfield, the player selects round-cornered squares to change the directions of electrical wire sections. Their primary goal is to complete circuits that run from batteries to light bulbs. They also earn coins and diamonds and perform light bulb skin upgrades.
Each level features one or more light bulbs and batteries. The player might need to use all the wire sections to connect a light bulb and battery or only a few sections. They might need to connect separate light bulbs to different batteries or ignore some wire sections and batteries to connect one long wire from one light bulb to one battery.
If the player makes a mistake, they can use a semicircular forward arrow button to reload a level. They can also skip a level by viewing an advertising video.
Power Light helps the player collect currency to perform upgrades. The player can play a spin wheel using the Lottery icon on the home screen. That said, they must view ad videos to collect prizes that include new light bulb skins, coins and diamonds. They can collect a daily sign-in bonus as well. They can upgrade light bulbs directly by paying with coins and diamonds or viewing videos.
