As an active player, you receive a Box containing additional COINS each month. The Box is linked to your gaming activity: it is an increase in your payout rate. The more active you are, the more additional COINS you will earn through the Monthly Box.
To take advantage of this, simply log in to your Circus account from the 1st to the 7th of each month*. You will then be redirected to a mini-game where 3 virtual boxes will be presented to you. Each one contains a mystery number of COINS. Choose one and find out how many COINS you have won. And the best part is, all the boxes are winners!
* Since it is linked to the payout rate, the Monthly Box is only available to active players.
