How do the treasure chests work?
When the treasure chests are available you will get this picture on the top right of the map page.
Click or tap on this and you will get this popup, which tells you how much time you have left to complete the task. The picture below says 1 minute, but it isn't correct as I had plenty of time to pass the levels needed.
The treasure chests are on certain levels and you have to clear those levels to get the treasure. The chests are usually on the first, third and 8th level you have to pass.
Once the popup appears just click OK to collect the rewards.
Some players have informed us that the chests are sitting over the next level they need to play and preventing them from opening the level. If this happens you need to refresh the game and everything should be OK.
The prizes are boosters and 2 hours of unlimited play.
