The rule is simple: Three cards are a set if, in each of a card's features (shape, color, fill, and count) every card matches the others, or no cards match each other. There are 6 such sets in the cards above; can you find them all?
Too hard?
Making one feature the same for all the cards makes for an
easier game.
Lastly...
This implementation takes its inspiration from the game of
Set produced by
Set Enterprises. And thanks to Andrea for
getting me hooked introducing me to Set. If you have any comments, suggestions, etc., please contact me
