Help, with hard levels

I cannot pass 392

That's not true @Diamond_Lim about being able to pass any level without using boosters or gold bars to carry on playing. That may true for the early levels but once you get into the levels in the 13000s using boosters or gold bars is the only way to progress through a high percentage of levels.

I am in the 14,050 been playing for over 10 years. I have passed many levels in the 12-14,000 without using gold or boosters.So yes it can be done!

I have also been playing for nearly this long and am now where you are in the game. To be fair to everyone else who is trying to catch up we need to admit that when we played the levels in the thousands they were a lot easier. It is only in the past few months that King have put deliberate impossible levels in there, and that they have stopped being generous with free boosters and gold. I don't deny that many levels are possible to achieve, but the point is that there are SOME impossible levels set to block players now. In fact King change levels from week to week to make some impossible by simultaneously removing moves and adding blockers. You may have been lucky to play those before the were changed.
