If you're not finding the right solution, then maybe you're not asking the right question.
Great fun!! I finally solved it after a week of trying.

This was great and thought it would keep our son busy a few days however he'd solved it in half an hour. But to give context he is expected to get an A* in his maths A level. However he was really impressed with it so, as presents go for a 17 year old teenager who loves maths, this was a hit.

Bought this for my spouse who loves puzzles. She figured it out in two days. She went at it logically with pen and paper first then found the starting position and the rest was easy. She’s pretty smart.

Don’t waste your money. Very poorly made and already falling apart out of the box. Very disappointing.

Bought for my adult son who loves puzzles, especially wooden ones. He loved it. Well made and gave loads of entertainment while he sat doing it on Christmas Day.
