I would say the two best free horse games I've found are howrse.com and the two horse isle games (horseisle.com). There is another game but it is in I thing Korean and you have to download it. Still, try out howrse.com and horseisle.com.
I have to agree with the first contributor - my daughter is horse mad and she used to love Howrse.com - she has outgrown it now. I would say it is good for anyone up to the Age of 14.
FunHorseGames.net may be one site that is worth checking out.
The best game site is moshi monsters
The best horse without the game of the year addition is the Black horse.
On AVH (A Virtual Horse Game Site) you can scroll down and there is a button that says "Guest", click on it and there you go! :) :P
Ok The Best Is Fantage!!! The Site Is:www.fantage.com
The Best Game Site Is WWW.Funny-Games.Biz With All The Categories Of Games (Even Online)
