Like every year, there is a christmas special. It’s a special challenge you only get from december 23rd: Play 5x against buddies to receive a present. Also, you can pass presents to buddies with lower prestige on your buddy list (Android only). You get 10 prestige whenever you do that!
By the way, the LUDETIS team also has christmas holidays, so only limited support is available.
We wish you a merry christmas and a happy new year!
