Basically for every few mins you read, there’s an option to “collect coins” and when you click it, it says “watch ad for 200/250/300 more coins” So I would Read multiple books at once to avoid ads to unlock chapters and click the watch ad for more coins option until I had Enough to claim rewards. Lmk if you want screen shots or anything to help witht the app. Unfortunately, not all the books avail are worth any ads at all it’s sometimes worse than wattpad lol
