This is a site that I use to study Latin. It has a bunch of Latin games that were created by teachers around the world and shared in this community. The website for Latin Games (and you can search for specific ones) is http://www.quia.com/shared/latin/
Some of the ones I have found useful are the following quizzes on conjugations:
http://www.quia.com/cz/422995.html?AP_rand=1925616065 and http://www.quia.com/cz/422996.html
There are all sorts of different kinds of games and quizzes (the ones above are only one sort). You can search or scroll and find ones that interest you.
Hope they are helpful,

[One of my favorites is Si Hoc Legere Scis, Nimium Eruditionis Habes]
