Indeed I did! The cards had me stumped for awhile though.. even with the hint... Might be good idea to exchange the symbol on the left side of the bottom equal sign for another symbol and do the same on the right card corner. Was also not obvious where to place the cards at first, but I think this small change to the hint will fix that too.
In no time things have gotten far more interesting, much more to this than meets the eye, but its given when nothing seems to meet the eye! XD
