How to Play

The puzzle grid consists of a series of numbered black squares. Your task is to draw arrows starting from each of these black squares in such a way so that the total number of white squares covered by arrows emanating from any black square equals exactly the number displayed. Arrows can go up, down, left or right, but can never cross another arrow. You must also fill every empty square on the grid with one arrow segment. Each puzzle has only one unique solution, and each can be solved using pure logical deduction.

Click/touch any numbered black square and drag up, down, left or right to start drawing an arrow in that direction. You can drag on existing arrow tips to increase/decrease their size, or drag the tip back to its originating black square to remove it completely from the grid.

Tips and Hints

• Start with the largest-numbered boxes, and see if any have size constraints that would "force" an arrow. I.E. if a 9 box has only 1 open square to the left, 2 below, and 2 to the right, at least four squares will need to be covered by an arrow in the up direction.
• Search for empty boxes on the grid that could only be reached by arrows from one numbered square because arrows from any other square would be too short to reach it. If you find one, you can place an arrow there immediately.

Rules of Play

• Every numbered black square must have exactly that number of combined arrow lengths emanating from it in the final solution.
• No two arrows can cross each other.
• Every square on the grid must be filled with an arrow.
• A number will turn green once it has arrows emanating from it with the correct combined length, but that does not necessarily mean those arrows are placed correctly.
