You will only need to achieve 1,000 ices within 7 days. We currently have under 6 days and 22 hours to complete it. Those who complete their 150 ices for the Family Progression daily, will be able to complete this Ice Season easily.
The Grand Prize for the current ongoing Ice Season, is the Rotator Shotty. The milestone rewards for the Bronze/Silver/Gold/Ruby/Diamond tiers are the same as the previous seasons.
