This map is actually easy! or that is what I feel
It is all about the center and the surrounding. The moves are walk on (all circles + all side circles no corner) , cross and all circles no center
If you write the additional values from 4 moves above and you will get the concept of this map instantly.
Sometimes, there are moves that give the same additional values to surrounding while give the different additional values to the center. These will help you reach the values you want at the center quickly.
Well enough hints!
There are level 1, 2, 3, 4, 5, 7, 8, 9, 10 and 11. Level 6 might give so much headache to author so there is none.
I give this map 5/5. Surprisingly, this is much easier than the first time I played 3-4 years ago. I have no idea why it is that way as well.
