Events are additional game content made available for a limited period of time.
They are usually associated with holidays (Christmas, Chinese New Year, Easter, Halloween, etc.) and are part of every major update. You can find out about upcoming events and their approximate dates in update description or in game news where they are announced in advance. All events have their own timers and end once time runs out.
Events feature: - a unique set of match-3 levels. - special match-3 mode or special tasks in the mansion. - a set of rewards for completing tasks. - themed decorations or temporary changes in the mansion. - discounts on in-game purchases and special offers.
IMPORTANT NOTE: Events don't help you with mansion restoration, which is why completing the tasks they include isn't required.
