1. [r9c6]=1=[r1c6]-1-[r1c3]=1=[r3c2]=8=[r2c2]-8-[r2c6](-6-[r8c6]-3-
[r9c6])=(ALS: r258c6)=8|9=[r5c6]-9-[r9c6], => r9c6<>3,9.

2. [r69c1]-4-[r7c1](=(ALS: r7c128)=4|1=[r7c8]-1-[r5c8]=1=[r6c9]-1-
[r6c2])=4=[r7c5]-4-[r3c5]=4=[r3c8]=8=[r3c2]=1= [r1c3]=3=[r1c1]-3-
[r7c1]-7-[r7c2]-3-[r6c2]-2-[r8c2]=2=[r8c7]=4=[r9c7](-4-[r9c1])-4-[r9c3]
=4=[r6c3]-4-[r6c1], => r6c1/r9c1<>4.

3. [r8c2]=2=[r9c1]=5=[r13c1]-5-[r2c2]-8-[r2c6]-6-[r8c6](-3-[r8c2])-3-
[r8c8]-5-[r8c2], => r8c2<>3,5.

4. [r3c1]=5=[r3c9]=6=[r2c8]-6-[r2c6]-8-[r2c2]-5-[r3c1], => r2c4/r2c5<>6; r2c4/r2c8<>8; r1c1/r1c3<>5.

5. [r8c5]=7=[r7c5]-7-[r7c2]-3-[r7c8]=(ALS: r7c89|r9c9)=3|2=[r9c9]-2-
[r9c1]=2=[r8c2]=7=[r8c5], => r8c5=7.

6. [r4c5]-9-[r5c6]=9|8=[r2c6]-8-[r1c4]=8=[r9c4]=9=[r79c5]-9-[r4c5], => r4c5<>9.

7. [r2c6]=8=[r2c2]=5=[r5c2]=3=[r6c2]=1=[r6c9]-1-[r5c8]=1=[r7c8]=3=
[r7c5]-3-[r8c6]-6-[r2c6], => r2c6<>6 and the puzzle is solved.
