Solution to the Sudoku level 2 game 6
<
R7C1 7 scan C2, C3 -- R7C2 5, scan R8, R9 -- R3C5 3, scan C6, R2 -- R2C4 4, scan C6 -- (6,7,9) cycle in C6, rest three cells form a DSA [1,2,5] -- R6C6 5 DSA [1,2,5] in C6 -- R6C8 6, DSA [4,6,8] in R6 -- R6C7 4, DSA [4,8] in R6 -- R6C5 8.
Furthermore, R3C9 4, scan C7, C8 -- R1C3 4, scan R2, R3, C1 -- R5C5 4, scan C4, C6, R4 -- R7C5 6, DSA [6, 7] in C5 -- R4C5 7 -- R7C9 1, DSA [1,3,9] in R7 -- R7C4 3, DSA [3,9] in R7 -- R7C7 9 -- R4C2 6, DSA [2,6,5] in R4 -- R4C4 2, DSA [2,5] in R4 -- R4C3 5.
The following figure shows the results of our efforts till now with two cycles (1,2) and (1,7) formed in C6 and C4 respectively. Additionally we have shown a two digit DSA [1,8] in cell R8C3.
Then further on, R5C6 1, DSA cancel -- R8C6 2, DSA cancel -- R5C4 6 -- R3C8 1, scan R1, C7 -- R1C7 2, scan R2, C8 -- R5C9 2, scan C7, C8 -- R5C8 5, scan C7 -- R5C7 7 -- R1C8 7, scan C7 -- R2C7 8 -- R8C8 8 -- R8C3 1, DSA cancel -- R8C4 7, DSA cancel -- R9C4 1 -- R8C7 3 -- R9C7 6 -- R9C9 7 -- R1C6 9, DSA cancel.
The last steps, R3C6 6, DSA cancel -- R2C6 7 -- R1C1 8, scan R2, R3 -- R2C3 6, scan C2, R3 -- R2C2 1, scan R3 -- R3C1 2, scan C3 -- R3C3 9 -- R9C2 9, scan C3 -- R9C3 8 -- R5C3 3 -- R5C1 9 -- R5C2 8. End. Game solved.
