Olá, bom dia, recentemente eu estou aprendendo a técnica de X-wing e até agora eu entendi muito bem, se houver apenas dois candidatos em duas linhas, em que esses dois candidatos nas linhas ficam exatamente nas mesmas duas colunas, nós temos um X-wing (ou então ao contrário), mas o que eu queria saber (e que não vi nenhum exemplo no google) é se pode ter um x-wing em apenas duas caixas. O mais comum quando voce pesquisa no google é o x-wing formado aparecendo 4 caixas, 2 caixas eu nunca encontrei. Eu acredito que pode existir, pois nao quebraria nenhuma lógica do X-wing... agradeço qualquer ajuda

I’m experiencing since latest update iOS I think that numbers 6 to 9 are not visible on my keyboard screen,
so I’m not able to play the daily sudoku on here. Anyone else with the same problem and most interesting how can I solve this?

I really wanna get better at sudoku, I can do a medium difficulty one in about 8 minutes, but I feel like I'm missing a lot of strategy/knowledge, for example spotting naked singles is still a big challenge and everything above that like naked pairs, x wings etc. seems impossible.

Do you have any tips on how to improve?

People on here seem so good at what they do, I would love to learn from you.

Lots of love to anyone reading this ✌️

I’ve been staring at this for too long. I’m officially stumped. Is there a trick I’m missing? Any help is appreciated!

Can you guys please explain why it should only be 8 on the highlighted cell? Why can't it be put on the cell above it? I'm stuck on this puzzle for almost 2 hours.

Don't just solve it for me, please give me some advice on how to find new numbers to write down. I've been staring at this for so long and can't find anything. My notes are probably no big help, i seem to have forgotten to write some down. theyre probably innacurate

Couldn’t believe what I was seeing. But I was proud to have spotted it. Thanks to this subreddit for the help!
