Got a yellow bag from the lucky roulette for the first time..🎉

It's great that I got to improve my stats and received 45 lightning bolts, but I couldn't buy additional lightning bolts because I ran out of gems ㅜㅜ I could buy them, but I decided to give up since I need 80 gems to participate in the endurance competition event again.. I was happy to get extra lightning bolts by watching ads at the end for the blue and purple bags, but having to buy the yellow bag for 90 gems is outrageous😠
