Arrow Ring

There are numbers and arrow symbols in the grid, indicating the position and number of circles in the grid
Except for circles and existing arrow numbers, the remaining grids are marked as squares

The ultimate goal of the game is to find a square path that does not intersect and does not pass through a grid marked with circles and arrow numbers


* Arrows and numbers indicate how many black circles are in a row or column in which direction;
* Closed blocks can only pass through white squares that do not contain numbers or arrows;
* The numbers in the square indicate the number of black circles, for example, the number "3" contained in the square and the arrow pointing to the left indicate that there are three black circles on the left side of the square;
* Black circles must not be connected horizontally or vertically;
* There may be black circles in the grid without arrows indicating the direction.
