About this game

Line Loops is a challenging and interesting logic game where you need to draw a continuous closed loop to solve the puzzle.

1. The board consists of a number of numbers and a number of dots. Each number represents the number of dashed lines around the quadrilateral.

2. Connect the points with a straight line to make it a loop, and there can only be one loop. The number between the four points represents the number of lines around its quadrilateral.

3. Where there is no number, there is no limit to the number of dashes, and there can be no dashes around 0. The route cannot cross or branch.

What’s new

1. 盘面由若干个数字和若干个点组成。每一个数字，代表其周围四边形划线的数目。

2. 把点与点以直线相连，使之成为一个回路，且只能有一个回路。四点之间的数字代表在其四边形周围线的数目。

3. 在没有数字的地方，划线的数目没有任何限制，而0的四周则不能有任何划线。路线不能交叉，也不能有分岔。
