Construction tokens are used to activate additional construction slot. This feature allows to build/upgrade/demolish two buildings/decorations at the same time. Once you have collected enough tokens the next construction will be activated in the new slot, which will deduct the 50 tokens. You will then be able to add an additional construction to your regular slot.

PLEASE NOTE: As soon as you have 50 construction tokens available, any item you choose to construct will always be sent to the new construction slot first. This includes decorations with a rebuild time, such as decorations with Village Happiness. A dialogue will inform you when you have enough tokens to use the slot so please plan accordingly.

There is a limit on the amount of tokens that players can have at a time. With 50+ tokens you will no longer be able to collect them. You will have to use up those 50 tokens first to free up some space, after that it will be again possible to receive them until the amount reaches 50 and so on.
