While making moves in the game, a light streak gets left behind each token. These light connections are what inspired the game symbol.
In the front
Simple game play, just connect the tokens as they fall from gravity. Rotate the circle board to change the barriers between the tokens.
In the back
The mathematical backend is created to sustain complex logic, so knowledge and cognitive thinking are required in order to solve the gravity puzzle.
The more complex geometry, the more difficult the stages are.
