hearts ratings bug fix, list of tables bug fix

There was a bug in the update to the Hearts ratings last week which caused the losing players to get more points deducted from their Elo ratings than they should have. My apologies, I know some of you take the ratings very seriously!

I've applied a fix to the problem this morning. Anyone who would like to get their Elo ratings set back to where they were last Wednesday need only write to me and ask (marya@worldofcardgames.com). To do this, just make sure that you send me the email from the address that you registered with, so I know it's you. I will do this for people up until the end of November.

[Edit on Nov 24 2015: Only a small number of requests to reset Elo ratings have come in. After receiving negative feedback on the way this was being done, I decided to just go ahead and do the work to perform a bulk update of Elo ratings. Anyone who played at a ranked table prior to Nov 17 has had their Elo rating reset to the value from Nov 11, before the bug was introduced. To be clear, this was only done if it led to an increase in their ratings - I did not reset values that were lower.]

I've written a page about how the Elo ratings are computed at World of Card Games, so you can always check for yourself to make sure you are getting the correct results.

I've also applied a fix for the "list of tables", which had a bug that caused the list to stop updating. Third times the charm? I hope so!

list of tables bug fix, Pinochle bots improvement

This morning, the server was updated to repair a bug in the "list of tables". It's supposed to update every few seconds, but had stopped. This is now fixed.

I've spent a little bit of time updating the bots in Pinochle, based on feedback. They'll still need more work, but overall should be a little bit better in playing their cards now.

new features! chat after game, spades hand history

This morning, the server was down for a brief time in order to apply some updates.

Registered players can now chat after their game has finished at World of Card Games! After the game finishes, you will now see three buttons: "Home", "Chat", and "Play ..." (see screenshot below).

Clicking the "Home" button takes you back to the main home page, where you can decide what new game you want to play. Clicking the "Play ..." button takes you directly to a new game of the same type that you just finished (for example, Hearts or Spades).

Clicking the "Chat" button takes you to a "chat" table where only the registered players from the game you just finished are invited. This gives you time to discuss the game in as much detail as you like, should you care to do so. The "Chat" button goes away after 30 seconds, so be sure to use it as soon as possible if you are interested in a chat with your group of players. Caveat: No one is obliged to go to the chat table, so you may find that no one joins you there.

If any who played with you goes to the chat table after your game is finished, this chat table will show up in the list of tables. Here's a screenshot of how to recognize it:

Another new feature is the ability to save your "hand history" in Spades. The hand history is already familiar to those who play Euchre. Registered players can download the history of their previous hand, and replay it in the browser to review all the cards played, one step at a time. In Euchre, this feature can be a nice tool to discuss strategy. It is also very useful to report bugs in the bots to me. I'm hoping Spades players will find it useful as well. Sometimes, people report problems with the bots, but it's too time-consuming for me to figure out just what happened. With this new feature, if the bots make a boneheaded mistake, you can grab the hand history and send it to me with a description of what went wrong. I will be more likely to fix a problem when I know exactly what happened, and can reproduce the issue.

To download the hand history, click the old-fashioned "floppy disk" icon that appears next to your avatar after a hand has finished. You can see what it looks like in the screenshot here.

Hm, I can't believe I just called a floppy disk "old-fashioned"! :)

Another important change: at ranked tables, the Elo ratings now reward the first-place player only. Elo ratings in Hearts was discussed in the previous blog post. I did not receive a lot of feedback, one way or the other, about this... but most players appear to like the idea, so I've made the change. I will continue to keep track of any feedback on the issue. Please post to Facebook or Twitter or here on the blog if you have comments. (FYI: anonymous posts are not treated very seriously; anyone can post anonymously multiple times, so I don't consider them to be so useful.)
