As of November 28 the amount to of gold bars you earn for $3.99 dropped from 60 to 30 and still pay the same. That is a huge increase. Looks like a big money grab to me.
Hello @Darlene_Grigull and Welcome to the community. I would like to bring to your knowledge that the dev team creates levels that can be cleared without being dependent on gold bars. I'm on 620 @ the moment and haven't used a single gold bar. I agree that some levels are too tough and need lots of luck and skill to clear them but eventually you will get through if you stick to the level. Stay calm and happy crushing.
