Possible if i can use a randomiser in my game concept for a school project.

Hi everyone,

I'm making an Arduino based game for a school project of mine. You have 6 buttons and 9 lights. Every buttons lights up some lights and/of darkens some lights. Not all lights are used in every button. I also installed 2 selection buttons so that you can choose to play in easy or on hard. For easy you have to get the right 4 buttons in the right order to get all the lights on. Hard is the same but then with all 6 buttons that you have to get in the right order. The purpose of the game is to get all the lights lit. The only problem is that if i play again on easy it will be the same combination. Is there a way to randomly generate that so if you play easy again, you get a new 4 long combination that you have to solve. The part that I don't know how to do is how to make 6 buttons with random on and/or off lights to have a 4 long combination that lights them all up. If you need the code ask and I will put it in too but I don't think that's necessary in this case.
