I am the author of the second round of Puzzle Ramayan (Shading and Loops) being held on Logic Masters India this weekend. Here is a link: http://logicmastersindia.com/PR/201702/.
This is a practice puzzle for Bosnian Snake.
Rules (from IB): Locate a snake (a 1 cell-wide single continuous path) in the grid whose head and tail are given. The snake does not touch itself, even diagonally. Numbers outside the grid indicate the number of snake cells in that row/column. Numbers inside the grid indicate how many of the 8 cells around it are used by the snake. (The O's mark the head and tail of the snake in this puzzle formatting; in the IB, they are marked by black circles.)
