The fairs are available to all players of level 50 or above.

You can help your community and participate on the fair only in case you joined the community before the fair started.

After the fair the community members can receive the reward for every passed prize score. 3 the most active members who have earned the biggest amount of points get the special reward.  

You need to check the location where the fair actions should be performed (mostly in the Household).

In case you left community during the fair, you can`t participate on the current fair any more. Also the community member can`t be expelled during the fair if he earned even 1 point.

You need to collect the reward till the next fair starts otherwise the gifts disappear.
