K-2SO

K-2SO is a Premium Box Tsum. He is a Limited Time Event Tsum and is not obtainable through purchasing Premium Boxes outside of the event. He was introduced in tandem with the Japan Star Wars Rogue One Event (December 2016) and the second International Star Wars Event (April 2017). He was only available from Support Capsules in the International Event.

Information
K-2SO will turn all the Tsums into K-2SO droids. Tap on the droid with the glowing eyes to clear the center of Tsums. His base radius is SS in the Japanese version.

Strategy
Tapping the wrong droid, or not tapping at all, will only clear a very small amount of Tsums. The number of Tsums cleared will also decrease with time. You should tap the glowing eyes of K-2SO as soon as you can.
