What is a "gaited" horse?
"Gaited" horses can perform an extra gait beyond just walk/trot/canter/gallop, and it's designed to be smooth and comfortable to ride. Gaited horses can move without bouncing their rider, and so they are favored by people with injuries that would be irritated by a rough ride. Gaited horses in historical times were the chosen mounts of traveling doctors, priests, etc who roamed from town to town and spent many long hours in the saddle. Today, gaited horses are the stars of the show ring because their special gait is usually flashy and fun to watch.

What are "Horse Art Games"?
What it looks like, really! Create and train your own horse by drawing pictures of it. You can enter user-run dA shows judged either based on effort or by a Random Number Generator (RNG) and win prizes!
At H-I-G-H-S, we focus on playing horse art games with gaited horses. Both naturally-inherited gaits and specially-trained gaits are accepted. A couple of the breeds that are automatically accepted are the Tennessee Walking Horse, Hackney, Icelandic, Missouri Fox-Trotter, etc. Here is a full list or you can check out Wikipedia's list.
