Very interesting puzzle. After basics, the code for every single digit was such that none of the standard patterns were available; no x-wings, no kites, no coloring, etc. Looking at the bivalue cells, two URs offered no help and I believe only a single xy-wing existed. Very interesting.
I solved the puzzle by: | Quote: | xy-wing 128 with pivot 18 in r2c8,
xy-wing 268 with pivot 68 in r8c7.

| I played the Type 2 UR on 89, XY-Wing on 189, coloring on 1 and 9, and an XY-Wing on 891. |
