I've made a quick list of things you can do on Howrse that should help improve your game play. This is by no means an exhaustive list so take it with a grain of salt. Hopefully, it helps someone.
Take part in any current promotions. It's always a good idea to fulfill any daily objectives a promotion gives you. Do your best to complete them without spending too much equus or having to resort to using Passes. Promotions are one of the best ways to get free Black Market Items and other useful prizes.
Stroke Xanthos. It's worth taking a moment to pay a visit to Xanthos. You can stroke five a day and, if you're lucky, he might leave you a Horn of Plenty the next day.
Defrost Frost. This isn't quite as important as stroking Xanthos, but it's a quick and easy action and you may earn a Hypnos' Blanket for your trouble. You'll also be entered into the monthly drawing to win a Frost divine. You've got nothing to lose!
Work your Divines. If you're lucky enough to own any divines, make sure you set aside a little time to work them – especially those that have the chance of rewarding you with items or Diamonds. Most require some interaction from their owners or they won't produce their prizes. So be sure to work them or you risk missing out.
Age your pregnant mares. If you're in a hurry and don't have time to work all the horses in your breeding farms just focus on your pregnant mares. This can save you time and Ageing Points later on.
Work your foals. Take a minute or two to work your young foals. Foals under 6 months don't require boarding, so they're very easy to care for if you're in a hurry. They're great for farming Ageing Points. I always make a point of working mine.
Check your Equestrian Center. Check your Equestrian Center to see if you have any board extension requests or if your resources are running low. Be sure to monitor your crops as well!
Check and return your congratulations. This isn't a requirement, but it's a nice thing to do.
