Update 2.3.5 brings several changes to the game, including:

• New event modes with unique gameplay mechanics, which will be updated and improved in the future. These events are available for a limited time: 3 to 5 hours during the week and 8 to 12 hours on the weekend. To get rewards, you need event tokens, which you can earn by scoring goals or winning matches. Check the event info for more details.
• Updated rules for the Katy, Nancy, Vuvucela and Ovation effects: using a second Vuvucela or Ovation will now reset the turn duration instead of stacking the effect.
• Graphical improvements with new icon and logo, and redesign of clubs and rankings, to make it more consistent with the rest of the game.
