Game: pattrns

Ok. ok.. some of you might know this game as "SET" but having an online version of set rather than relying on cards gives it a more up to date feel.

This puzzle/game challenges your visual recognition skills and for someone slightly colorblind(me) it's tough. There's different levels of difficulty to choose from, so pick your own poison.
