Science Buddies: "Ask an Expert"

I got my project idea from this website, science buddies and I have decided to do the fun or frustrating one. I need help to come up with the procedure and experiment. My question is, "Is fun correlated with winning?" I was thinking to get two groups of volunteers and let one group play an easy mode for an online game and one group the hard mode and let them take a survey afterwards to determine whether they found the game fun or boring. Im not sure if I should time them while playing and Im not sure what game to pick. Please help P.S the science fair is due in 4 days and I have not even started.

Oh no! I hope it's not too late to respond, but I apologize if we missed your deadline. Google has several games that could work for this type of experiment. The Google games "Minesweeper" and "Solitaire" both have easy and hard modes - you can find these just by searching either "Google Minesweeper" or "Google Solitaire." Time can be an interesting aspect to consider if you would like, but I don't think it's necessary for the experiment - up to you!
Hopefully this is helpful!
Good luck,
Chloe
