Discovering Rikudo: Rules and Tips

Tip #1: You won't trap cells.! At the end the grid must be full. If a cell is encircled while filling the grid, it becomes trapped. Identify these situations and avoid them.

Tip #2: You will anticipate your path. Two paths cannot cross each other. Search for possible crossing paths and choose other available paths.

Tip #3: Think about uniqueness. The grid has a unique solution. Therefore if you can switch two numbers next to each other without disrupting the main path, it means that it is not the solution!
