# Realistic Physics-Based Puzzles This game allows you to build circuits from Scratch! Yes, this game simulates exactly what happens when you connect a few batteries, bulbs and switches in the order you do so in the game. Most levels involve the use of a freestyle circuit editor, where you can drag and drop circuit components onto a grid based box. The game constantly checks if your circuits fulfils the conditions to pass the level and will inform you once you do. # Challenging and unique Levels While there are easy levels to get you warmed up, some of the levels are notoriously difficult and will keep you busy for hours on end. Most of the gameplay will revolve around build circuits to simulate real life logic gates, where the switches act as input and the bulbs as output. The below image is a sample exclusive-or logic gate, also known as the XOR gate. This is a easy-moderate difficulty level. There are 2 switches and 1 bulb, hence 4 possible combinations of switches, off off, on off, off on and on on. The circuit must behave such that when both switches are open or both are closed, the bulb is off. Otherwise, the bulb must be on. This is seen from the goal state at the left side as well. # Learn about electricity With the simplified drag and drop grid based system of this game, it is incredibly easy to pick up but hard to master. This game is based on realistic physics, so completing this game will teach you a lot about electricity. It is both fun and educational.
