Engineering Aids

The Engineering Aids Collection is a collection that can be combined in the game.

Once you have collected at least 1 of each item in the Engineering Aids collection, along with the required number of combining elements for the collection, the combine button on the right hand side of the collection will turn green. You will be able to combine the collection and receive your rewards. If the combine button is brown, then you are either missing one or more of the collection items, or you do not have enough of one or more of the required combining elements to combine the collection.

The items needed to combine the Amusement Park collection can be won as a reward for successfully investigating certain pictures and winning certain puzzle games. These collection items can be won both within, as well as, before and after the quests for them. They can also be randomly rewarded by the Collector's desktop award or as a random reward when visiting friends. The items belonging to this collection can be gifted to friends (from your own inventory) and received as gifts from friends.

The required combining elements to combine the collection, once all 5 items have been found, can also be won as a reward for successfully investigating certain pictures and winning certain puzzle games. They can also be given to friends as a free gift (not out of your own inventory) and received from friends as gifts.

See List of Collections for all collections currently available in the game and the rewards for combining them.

Note: If you are trying to search for a collection based on an item in that collection, see List of Collection Items instead. This list only states the name of the collection and the rewards for combining that collection.
