How do you train a horse to play games like Hide and seek and football?

Hi, i have a foal, about 4 weeks old i think, mabye slightly more, mite be closer to two months. Well, i want to train him to do some cool games, so far ive managed to get him to play tag.

Are there any good free online train driving simulator games online?

Do you know any good train sim games online? I can find some Japanese games but some of them are quite hard to understand.

Cheers in advance.
