Each level consists of 3 rounds. Levels require coins to start, and you win Coins when all 3 rounds are complete and the level is over.
A round (or specific question) is completed as soon as all answers are found, or you receive 3 strikes. If you received 3 strikes but submitted at least one correct answer, you will still move on to the next round.
The 3rd round in a level is worth extra points.
If you close the game in the middle of a level, you will forfeit the progress made during that level. Keep in mind this will not refund the Coins spent to start the level. We recommend not beginning a level unless you are prepared to complete it.
