UPDATE Mar 15, 2017. The chest cycle in this version stays THE SAME. Meaning there's no need to update the app. SMC, Legendary, and Epic are randomly distributed with the rate of 1/500 for SMC, 1/240 or 1/480 for Legendary and Epic chests If you receive a SMC, Legendary or Epic, please choose your NEXT 100% CHEST BECAUSE THEY WILL REPLACE THAT CHEST.
