Renzoku also known as Neighbours a variation of the Futoshiki logic puzzle.
The rules are simple.
You have to fill the grid with numbers so that:
- The numbers are from 1 to the size of the grid i.e. 1 to 5 for a 5x5 puzzle.
- Each row and column must contain only one instance of each number.
- A dot between 2 cells indicates that those 2 numbers should be consecutive. If there is no dot then the numbers should NOT be consecutive.
- For bigger puzzles the letters (A,B,C etc.) follow after the number 9.
