I’m also stuck on 11764 have been for two days now. The game offers me 30 extra moves for 10 gold bars and I have none. It’s ridiculous to be stuck for so long. I do hope you have finally gotten a lucky board and have moved on.
@PierreRoelandt Totally agree, don't think it's mathematically possible. But do you have 24 moves in online version? I have it on iOS but still only 18 moves on laptop.
