Yu-Gi-Oh! Duel Links

					
Free Gems on Map:

On each screen of the Duel Worlds there are hidden free gems which you can collect by tapping on certain background items. If you tap on something and a special animation plays you will be awarded between 1-5 gems. (this is random and each spot may work more than once a day). Following is a list of places to tap on to see animations.
The fountain next to the Gate.

The lights leading to the PvP Arena.

The dome above the card Shop.

The trash can in front of the Card Studio.
