List of all dxSudokus: / @dxsudokuchannel In this video the puzzle-solving technique called Alternate Inference Chains (AICs) along with Extionsions or X-Nodes will be demonstrated.
Welcome Back Dx. Good to see you making videos again. I like your approach, especially how you look ahead one link to determine if the weak links lead to a strong link, like with the 2s. Very helpful in finding useful AICs.
I did a new video showing AICs with X-nodes or Extensions. It was a really hard puzzle. It took 5 AIC sequences to solve it Let me know if you have a good puzzles you want me to try solving with this method.
