Triple shoot trick to solve diabolical puzzle

Mahadevan

Hi all,
I really need some inputs on this.

(not able to post url with puzzle image)

Experience shows that in Diabolical puzzle triplets are difficult to spot. Hence the Arrow shoot / Triple shoot
trick has been devised and experimented.

Authenticity of this trick has to be explored through other puzzles.

After fixing the straight numbers in all nonets, some twins in the same nonets or triplets in two regions or cells triplet in two cells
were pencilled.

Though the author in the above book suggested to apply Adriane's trick i.e.
try with one approach and in case of failure, try the other route.

But a successful attempt was made to solve this puzzle with a new approach i.e. "Arrow shoot".

The purpose is to fix the 3 and 5 in Nonet 1 i.e. either 3 left or right.

Scrutinise the Nonet 7 wher 3s are in two rows i.e. R7 and R8. This nonet has 3s in a row (R8) and two 3s in R7
Irrespective of the row the 3s in this nonet have formed an arrow i.e. three 3s in a row and 3 in the middle of R7.
With the arrow like 3s if the journey starts to fix the 3 in Nonet, the journey ends in nonet 1 - R3 - C2.

Hence R3 C3 becomes 5.
(Of course 35 in Nonet 4 was written after resolving Nonet 1 and 7

After this the puzzle has an easy flow and can be completed in the normal way.

Anyone can suggest a still better method.

Definition of some terminologies
Nonet : a Region consisting of 9 cells

R = Row
C = Column
