Need help with coding project. Working on electronic challenge game.

Hi all

This is my first forum post so please let me know if I've done this right,

I am a designer working on a real like version of the bomb from Keep talking and nobody explodes (without the explosives of course) and I need help with the coding. I am more capable working with hardware and I am working on creating an acrylic housing but I can't work with the code apart from on a very basic level. I would love any feedback on how to create the code for the game. Each challenge will run off separate arduinos only communicated together when they have to. Unless you have any other ideas in which case I will welcome them.

Many Thanks
