Common cause is a new event where you can team up with other players to unlock puzzles and receive valuable rewards. The event is still in the test mode, that is why it is not available for all the players.

Tap on the Common cause icon at the bottom of the screen.

To get puzzle pieces, you need to complete stages of common progress together with other players. To track your personal progress, tap on the cart icon on the right.

To fill your personal progress bar, you need to get event points by spending energy in any way: cut down obstacles, remove predators etc. When the personal progress bar is full, you will get endless tokens - tap on the tokens to get them.

You can exchange your endless tokens to valuable rewards in the endless shop that you will see in the lower part of the screen. The shop refreshes its stock after each purchase.

The more personal goals you achieve, the more points you will add to the common cause and the more puzzle pieces your will receive.

At the end of the event, you'll receive the rewards from the chest in the common progress section, and any remaining event points and endless tokens will be converted to other resources.
