From time to time you'll find drift bottles will float to shore on your land. Inside them are ads that you can watch to earn free GoCoins. For each ad you watch you'll immediately earn 1 GoCoin. Please note, you will never find more than 8 drift bottles per day. There is a limit to the ads we can provide. If you do not see a drift bottle you can try closing To-Do Adventure and waiting 5-10 minutes before coming back to check again.
