This morning they increased the level caps for both players and Tsums in the international version of the game!!
The new player level cap is now 200 (instead of 99) and the Tsum level cap should now be 50 (instead of 30). This increase was done without an actual app update so you should see the new caps as soon as you log in. For all the players that have been stuck at the level cap for awhile this is a great change! This also brings the International game more in line with the Japanese game where the player level cap is 300 and the Tsum level cap is also 50.
