To solve it using just VH moves, there's a 58-2 XY Wing at r1c19,r2c8 (-2r1c7,-2r2c12) which opens up a 29-5 XY Wing at r29c1,r9c7 (-5r2c7) which solves it. |

Using just VH moves the X Wing on 5's in rows 3 and 8 (-5r7c3, -5r2c9) opens up a 19-2 XY Wing (with pivot at r7c3) which solves it (-2r7c12, -2r9c7). |

Oh, I see. I should have realized that. I don't remember ever seeing the Draw/Play page ever supporting Squigglies. As far as I know it has only ever supported the classical Sudokus. |

Thanks for the puzzle peter. First I used an X Wing on 7's (I think it was in rows 4 and 6). Then I used an X Wing on 1's (I think it was in columns 1 and 4). And I think they were both necessary? |
