Alpha chests yield big rewards for the fiercest vikings!

The more Alphas you defeat, the greater the rewards that your chest contains.

Each chest is individual to you and its level is determined by the average star difficulty of the last five Alpha battles in which the whole Clan has participated. For example, if the last five Alpha battles were 5-star, 5-star, 5-star, 6-star and 7-star, you will progress to a level 6 chest. The chest level will always be rounded up.
