I think that this game, like all online games, is based on the bonus you have to buy. There is no trick, you just have to buy the match. These events are one of the many ways to stimulate purchases ;)

Or give a bonus day to those who complete the three missions in one day. In the sense of removing a day to 7 of the chain each time you complete the three missions in one day

If you can't say something nice, don't say nothing at all remove the presents negative, lower prices in pennies type 10, 20 or maximum 100 crystals and perhaps can be a nice thing

title grabs customers ... article poor ... but it's just a point of view

i miss the times when the cost of a video game was predetermined and fixed although expensive ... then you had to play only this game, like all online games, is not a matter of skill but of wallet winner is never who plays and so who pays gets excited and thinks he/she's a great tanker, feeling entitled to call common players "garbage players" in battle proud to be a garbage player

I do not like one turrets discount for an hour! it discriminates against those who already have this turret or can not upgrade. it discriminates against those who in the hour of the discount will be in the middle of the night. it's discriminatory because it is designed to leave empty-handed most of the players Thanks for the 2x. It's always much appreciated!
