Earning coins through games
You will earn coins on Sumdog for each question you answer correctly (on your 1st attempt) when playing any of the games. If you answer a question incorrectly you will not earn coins for that question.
Each question will show the amount of coins that can be earned for answering the question correctly. This is displayed at the top left next to the question. Some of the questions can earn you up to 3 coins.
The coin bag at the bottom of the screen will show you how many coins you have earned in the current game.
