Let's play the sixth Sudoku game at second level hardness
This is the sixth game play at second level Sudoku.
We won't play this game with great deliberation and analysis. We will use naturally the repertoire of techniques that we have developed till now as required.
We will use DSA technique and Cycle concept more frequently. Nevertheless quick scan of row and column will always be a staple technique.
The Sudoku second level 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.
