## Let's play the fifth Sudoku game at second level hardness

This is the fifth game play at second level Sudoku. By now we have developed a rhythm and strategy of cell solving. We try for quick scan, but usually don't try too hard for checking all scan possibilities comprehensively. More often than not, the DSA technique produces quick results. That's what our experience says.

So we have formed a mixed strategy of first scan, not to the deepest level, then DSA test in the most favorable zones. Usually we never go for writing 3 digit DSAs in a cell. Our target usually is to form a two or three digit cycle and reap its benefits.

To know what is a **cycle** or **DSA** you may refer to our * first* and

*. From this game on, we will straightway go for game play without any explanation on Sudoku in general.*

**R1C1 6,** scan R2, R3, C3 -- **R4C8 6**, scan R5, R6, C9 -- **R7C6 6,** scan C4, C5 -- **R9C2 6**, scan R7, R8, C1, C3 6 over -- **R6C6 8**, scan R4, R5 -- **R5C5 4**, scan C4 -- **R4C4 2** -- **R2C9 4**, scan R1, R3, C8 -- **R6C7 4**, scan C8, C9.

Then again, **R8C5 9**, DSA [8,9] in C5 -- **R2C5 8** -- **R9C4 7**, scan R7 -- **R7C4 5** -- **R3C4 9** -- **Cycle** (1,5) formed in R8 -- **R8C2 7**, cycle (1,5) in R8 -- **R3C2 2**, scan C3 -- **R5C9 3**, scan C8, R4.

Observe another cycle (3,5,7) formed in C3. We write minimum amount DSAs in Cells, especially the useful ones such as cycles and two digit DSAs.

**R5C2 1**, DSA [1,2,9] in R5 -- **R5C8 9**, DSA [2,9] in R5 -- **R5C1 2** -- **R8C1 5** DSA cancel by C1 -- **R8C7 1** -- **R6C8 5**, DSA [5,3,9] in R6 -- **R4C9 1** -- **R6C3 3**, DSA [3,9] in R6 -- **R6C1 9.**

Then further on, **R2C8 7**, DSA cancel -- **R2C3 5,** DSA cancel -- **R9C1 8,** DSA [8,3] in C1 -- **R7C1 3** -- **R7C2 4**, DSA [5,4] in C2 -- **R4C2 5** -- **R4C3 4** -- **R7C3 9,** DSA [1,9] in C3 -- **R9C3 1.**

Let us produce the results achieved till now.

Proceeding further, **R7C7 2**, DSA [8,2] in R7 -- **R7C8 8** -- **R1C8 2**, scan C7, C9, R3 -- **R3C8 1**, scan C7, C9 -- **R1C6 1**, scan R3 -- **R3C6 7** --** R3C3 3**, DSA cancel -- **R1C3 7** -- **R3C7 5**, DSA [5,8] in R3.

And the last steps, **R3C9 8** -- **R1C9 9**, DSA [3,9] in R1 -- **R1C7 3** -- **R9C7 9** -- **R9C9 5. **End. Game solved.

#### A special note for you

*We haven't tried to optimize. So we feel that this more complex game is solvable by following an easier path.*

**You should try to reach one of the simpler solutions. **

Lastly, we leave a game for you to solve.

### A game for you to solve

We leave you here with a new game for you to solve. In our next session we will present its solution and another new game.
