## Let's solve the eighth Sudoku level 2 game in a quick natural way

With experience in solving Sudoku level 2 games, we'll solve this Sudoku level 2 game 8 using whichever technique gives us the immediate valid cell hit.

We will play this game naturally with moves that stream in one after the other.

Occasionally as we are stuck, we start writing mainly two digit DSAs in favorable cells till we get a break again. This carefree way of playing is possible because we have developed a repertoire of techniques through our Sudoku game playing past few weeks.

We have learned new techniques and used the techniques modifying them and tuning them as required. In short we have learned how to play Sudoku comfortably with confidence. It is possible as these level 2 Sudoku games are still easy to solve.

The same method of learning-doing-learning we employ when we go into any new area.

Usually we will still use row-column scan, but use of DSA is gaining favor as well as cycles. To know what a **cycle** or **DSA** is you may refer to our * first* and

### Solution to the Sudoku level 2 game 8

**R6C9 1**, scan R4, R5, C8 -- **R3C9 2**, scan C7, C8, R2 -- **R1C4 2**, scan R2, R3 -- **R4C6 2**, scan C4 -- **R6C4 9** -- R7C6 5, scan C4, C5, R9 -- **R9C6 8**, scan C4, C5 -- **R7C5 3**, DSA [1,3,6] in 9-cell bottom middle large square -- **R3C5 4** -- **cycle (1,6)** formed in cells R7C4 and R8C4 in column C4.

Then again, **R3C4 3**, cycle (1,6) in C4 -- **R3C6 1**, scan R2 -- **R2C6 7** -- **R1C2 1,** scan R2, R3, C3 -- **R2C1 3**, scan R3, C3 -- **R2C9 9**, DSA [4,9] in R2 -- **R2C3 4** -- **R4C9 3,** DSA [3,6,7,8] in C9, this is a long DSA, but we try long DSAs also -- **R5C9 6**, DSA [6,7,8] in C9 -- **R8C9 8**, DSA [7,8] in C9 -- **R7C9 7** -- **R6C8 7**, scan R4, R5 -- **R3C87**, scan R1, R2, C8 -- **R9C2 7**, scan R7, R8, C3, 7 over -- **R9C3 6**, DSA [1,3,6] in R9 -- **R9C8 3**, DSA [1,3] in R9 -- **R9C7 1**.

The following figure shows the results of our efforts till now. Let us go over to the next stage.

Then further on, **R6C3 2** DSA cancel -- **R7C1 2**, scan c2, C3, R8 -- **R7C3 8**, DSA [5,8,9] in C3 -- **R1C3 5,** DSA cancel --** R3C3 9** -- **R5C2 3**, scan C1, R4, R6 -- **R1C7 3**, DSA cancel -- **R1C8 8** -- **R3C8 5** -- **R4C7 5**, scan C8 -- **R4C8 4**, scan R5 -- **R5C8 9** -- **R7C8 6** -- **R7C4 1**, DSA cancel -- **R8C4 6** --** R7C7 9**, scan R8 -- **R8C8 4** -- **R8C1 1**.

And then the last steps, **R7C2 4** -- **R4C1 8**, DSA [8,9] in R4 -- **R4C2 9** -- R5C1 5 -- **R3C2 8**, scan C1 -- **R3C1 6** -- **R6C1 4** --** R6C2 6.** 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.
