We downloaded the exsiting design drawing from <https://www.instructables.com/Crack-the-Code-Game-Arduino-Based-Puzzle-Box/>. The size of the original was quite small so we scaled up by utilizing Fusion 360. Since we added a game, we also design a maze on it. You can see it in detail below.

Initially, separate Arduinos were used for the Simon Says game and the Crack the code game

But the limited space within the hardware –the cube made it impractical to house multiple Arduinos. So we are opted to integrate both games into a single Arduino system. 

Because the system requires the increased nuber of pins required, we decided to replace the original Arduino boards with an Arduino Mega. As a consequence, we had to redefine all pin assignments from scratch to accommodate the combined functionality. 

We encountered specific challenges with Tx0 and Rx0 pins (serial communication pins). Initially we attempted to utilize these pins but met extra issues so it prompted a return to the original pin configuration strategy.
