Becki M, you may already know this, but just in case: As Sam describes above, there's a way to play full online matches against bots only, if you wanted to get more experienced at the games before taking on a real player.
From the main menu, click on the "Inn" icon instead of the green dice "Games" one. Click on the game you want to play. Click on "Access to the table is limited". If you aren't Friended to other real players, click on "Only Friends" then "Open Table"; if you ARE friended, but want to play a bot, click on "Access by link only", then "Open Table", then "OK" at bottom of pop-up window. Either of these options will open a table in the Inn that simply counts down a few seconds than allows you to "Play With A Bot".
It's an excellent way to get a number of games under your belt, learn the intricacies of the games, and gain confidence. Just note it doesn't work for Cartographers, where you can't play bots, and full games cost more food than training.
