The site was updated this morning to fix a few bugs.
In Gin Rummy, there was a bug which caused your deadwood to be optimized incorrectly when your opponent declared "Gin". This had been reported to me a few times, but I was never able to reproduce the issue. Thanks to Alagon for reporting it and also sending in the hand history! With the hand history, I was able to reproduce the issue, and then I could fix it pretty quickly. (If you want to download a "replayer" for the previous hand, click the little floppy disk image that appears near your avatar after the hand finishes.)
Marie-Michele has reported a few bugs with the Euchre bots, including hand histories. Those hand histories make it possible for me to fix the problems. Most recently, the bot was seen to delay in playing the right bower to take a trick. This has been fixed. The Euchre bots are now a little bit smarter, and will be better teammates (or opponents!). Thank you, Marie-Michele!
