### Different Neighbours

Posted:

**Sat 19 Oct, 2019 7:50 am**Whenever I solve a different neighbours puzzle, I tend to painstakingly pencilmark numbers until I get somewhere. This normally allows me to solve the puzzle eventually, but it is not quick. Is there a trick (or multiple!) to solving this kind of puzzle more quickly?

Also, there is clearly a lot of potential for bifurcation, as there tends to be a lot of bi-value cells. However, normal bifurcation (writing out candidate in each cell) would take a lot of time and effort. Is there a quicker way to bifurcate?

Finally, on a video regarding the A.R.T method for solving sudoku (discovered by Sam Cappleman-Lynes, it seems!), someone commented that this method was applicable to suguru (capsules) and different neighbours. However, I have no idea where best to place the givens to make the puzzle as easy as possible, and I am not sure if this would save any time over solving the puzzle normally (as there is so much rearrangement needed at the end of the puzzle). Does anyone out there use this method to solve different neighbours?

Responses would be greatly appreciated!
