I have discovered this site a few weeks ago. I am evaluting different type of puzzles before deciding to subscribe. Today, I look for Hitori puzzles for the first time. I looked for the example in the instructions. But, even if I reached quickly to the conclusions explained there, I donĀ“t see how to proceed. There is someting that is escaping me. The two cells already shaded are too far from the borders .... Is that possible that someone could tell me how to reach the next cell to shadow? Thanks in advance.

Ps: I have already shaded cell with a '4' at the fifth column and sixth row. From there please ...

These are not easy to do initially I found, carbar, but am getting the idea now after much practice. In the example not all cells have been unshaded that can be, look up and down the columns and check that you have got them all before moving on.

I find it helps me then to shade in with a colour all cells that occur more than once in a row/column, so I know which ones to concentrate on.

On the bottom row there are three 3s and two of them shaded would block in another number so only one will be shaded the 3rd must therefore be shaded. If you have 2 together and a third the same in a row/column then the one on its own has to be shaded. Look for places where shading in would block cells in.

If you can't see a way forward, try using a colour and experiment, this sometimes helps when you are new to the puzzles, but some on this site like to do everything by logic, but this is a counsel of perfection!:)

Thank you. The situation of the three 3s on the bottom line should be evident. I'm trying to going on.
