Notice: For deeper scramble training (lengths 10 and 11), try the unified edition: xcross_pairing_trainer_new.html (Supports Lengths 10 & 11).
Warning: This scrambler allocates ~600 MB of memory (RAM) locally on first run. Initial initialization may take from several tens of seconds up to a few minutes depending on your device. The solver automatically selects the optimal configuration.



Note: Different search instances are launched for adjacent pairs and diagonal pairs. Initial generation takes time for each.
