Does anyone else use them? For those of you not familiar, many if not all online sites allow you to have the cards represented by the normal Black Spades and Red Hearts but swap in Green Clovers and Blue Diamonds. I find this "Lucky Charms" mode to be INCREDIBLY useful especially because am playing Stud on four or five tables squished down on my laptop screen so the pips are only a few pixels wide. Being in four color mode makes it soooo much easier to process flushes and in particular when I am playing Stud where I want to see how many of my flush outs are dead. If you haven't tried it yet, I recommend it.
P.S. I also noticed that in the Cake Hand History pages, there is even a checkbox to view the hand in four color.
P.P.S. There are also physical four color cards for playing live games. Can't really warm up to that idea though.
P.P.P.S. I am glad they chose the colors that they did for the 3rd and 4th suits. I think that those were the most appropriate color choices that they could have come up with. Red Hearts is a natural choice. Green Clovers totally makes sense. Black Spades also a no brainer. And that leave Diamonds which generally have no distinct hue to pick up the only reasonable fourth color remaining, Blue.
