Restricted Instances can be done daily. Restricted Instances can only be done 3 times a day for free and one extra time daily if a Passport is used.
Each time a player does a Restricted Instance, the player will win experience points, badge points, and a Constellation Pass which is used to gain access to Constellations Instances. Completing a Restricted Instance also will get you a Holiday Chest which contains random items such as He3 packs, Gold Packs, Boosts, Revival Cards, Passports, Healing Cards, etc.
On February 13 2014 number of free runs has been increased to 3 times per day.
