The goal of this game is to collect as many coins as you can by buying hash rates. The price of them goes up as you purchase them, so it might start to get cheaper to buy the more outputting hash rates later on. To start making DogeCoin, simply click the DogeCoin, and you will receive a single DogeCoin. The first hash rate upgrade is 20 clicks, so get clicking! To purchase kH/s, see which one you can afford, and then click the yellowish button. You will then see your kH/s rate at the bottom left go up, and your coins will increase every 2.5 seconds. If you use an auto clicker, the button will try and hide from you, so no cheating!
