I saw on YouTube videos of levels are not all levels can complete without boosters. 4 or 5 levels in 1 episode (15 levels) are impossible without boosters or extra moves.
My friend has been stuck on the same level for over 5 months. But last month he saw that the level is even harder than the previous version. Now he can't complete it without making extra moves. He only has 6 gold bars! And he refuses to buy money for more gold bars!! He said: “This game is a paid game for complete a impossible hard level and I can’t complete!! Because I have only 6 gold bars and no more! 😡”
This game become less fun to no fun!
