World of Card Games

All of the card games at World of Card Games have tutorials. Here are the links for all of them:

Hearts tutorial
Spades tutorial
Go Fish tutorial
Double Deck Pinochle tutorial
Twenty-Nine tutorial
Three-Five-Eight tutorial
Euchre tutorial
Gin Rummy tutorial

If you are very new to a game, these tutorials are a good place to start.

Once you have finished the tutorial, you may want to try playing some games against the "bots" (so all your opponents are computer opponents). That way, you don't have to worry about anyone being impatient or rushing you because you are not familiar with the rules.

To play with just bots, go to World of Card Games, and click the Options button for your game:

The Euchre Options button is to the left of the Euchre game panel

In the Options panel that pops up, check the "Private Table" checkbox, and make sure that the private table name is set to "none":

How to play with bots only: check the Private Table option and keep the name "none"

Click the OK button to save these options.

From now on, when you click that game panel, you will be taken to a table where you will just be playing against bots.

If you want to go back to playing with a mixture of humans and bots, make sure you uncheck the Private Table checkbox again.

By the way, each game at the site has a home page. This page has some useful links together with the "help" text, which describes the complete set of rules, conveniently displayed in a larger format. Here are links to all of the home pages for each game at the site:
