Loop By Numbers is an interesting logic puzzle based on the popular Rundweg (Slitherlink) puzzle type. This puzzle variation appeared in the Oguz Atay Puzzle Contest (OAPC-7) and combines classical loop-drawing mechanics with additional numerical clues. If you enjoy solving Slitherlink puzzles, loop puzzles, and championship-style brain teasers, this challenge offers a rewarding test of logical deduction and careful observation.
Rules of Loop By Numbers Puzzle
Draw a loop into the diagram following the usual "Rundweg" (Slitherlink) rules (A digit inside a cell indicates the number of its edges used by the loop). The numbers outside the diagram provide additional information about how many fields of this column/row are inside the loop. Each number represents one group of fields inside the loop. Each group contains linked fields equal to its number. Different groups must have at least one field outside the loop between them. Given clues are in increasing order.
