Multiple object quiz

Hi all, brand new user. 

I am making a grid of 25 objects that a user selects after a matching word appears on the slide. Basically a large bingo game.  I have all the states for the objects working/ buttons but now I am wondering what the best way to actually structure the game. Do I make 25 slides and have the different question on each slide and use triggers (doable) or freeform quiz or something else.  I have made it on a smaller level but when its this large I can't see an efficient way to make it. 

thanks
