RULES AND FEATURES
Laying a serious power grid requires appropriate qualifications. But in this game you do not have to count the electrical parameters of a complex electrical circuit. In other words, you won't need Ohm's and Kirchhoff's laws here. You just need to properly connect the power source to all the lights on the network.
Initially, the chain is disassembled, more precisely, the cable segments are in their places, but they are not turned as they should be. The goal of the puzzle is to find out from you how to deploy them correctly. In many ways, the game resembles the famous plumber, with the only difference that there are pipes, valves and taps, and here batteries and light bulbs.
Note that the color of the battery is green, and the light bulbs in the circuit are multi-colored, including green too. This should not confuse you. A light bulb of any color will light up when it is connected to a power source, that is, do not pay attention to the color. Proper network assembly is important.
You will learn about the results of the correctness of your assembly immediately, online, because the diagram shows whether all the lamps are lit up or not. Moreover, the light bulb can light up even if the circuit is not closed (which generally violates the laws of electrical engineering). But the correct solution will still only be one in which the circuit looks like a single whole, and does not contain cable fragments sticking out to nowhere.
To understand the rules and mechanics of the game, first play on a simple (Easy) level (there are only a couple of light bulbs), and only then, having mastered, move on to more complex ones. Please note the time taken into account here. Keep an eye on the game timer (bottom left). If you don't have time to assemble the chain before it expires, you will have to repeat the assembly.
