In the table of these Tap-in rewards it says that for having spent 99 credits I will receive 1x kitten ball ( one ball or a sleeve of 3, I did not know) and XP boost.
So I use 99 credits to buy me a sleeve of my old faithful G13-S.
But surprise! I received 7 kitten balls, XP boost and 3 G12-S balls of different colours. Good deal for 99 credits!
What do you say? Did I miss something? Is it a bug? or Am I lucky and take advantage lol.
