How do you earn coins on my horse game

You earn a few coins when you play the paddock care game and the muck out game. And when you groom your horse. The best way to get the money is under the tab with a picture of coins and an up arrow. You can choose from the different tasks to earn money. Once you've chosen a task you press start and after the set amount of time you go back to that tab and press "Ready" to collect your coins. You also earn coins when you win a competition.
