Why is this so hard !!! The rules are so simple, the game is telling me there are 3 sets in these 12 cards and I tell you I am STRUGGLING ;D
My brain must be wired wrong for this game because I feel just so dumb trying to find the set or sets that are there.
Didn;t stop me from trying my hardest and getting on the leaderboard with 90. Chased the mythical 100 but it didn;t happen :)
Great job !
PS: Pausing the game should invalidate the score for the leaderboard because it's very easy to take a screenshot, pause, find the set, rinse and repeat for an insanely high score ;P
