However these Sudoku puzzles are with Irregular grid.

I have created one for my Sudoku Variants Series. You can find it here.

And there was a puzzle of this kind in the LMI-test Road to London from last year.

There is one in this year's WSC IB (Page-15): http://www.wscwpc2015.org/wsc2015_instructions.pdf
It is not Irregular.

sorry

Of the puzzles you solved/attempted, how well did the point values reflect the difficulty?	Most puzzles were worth the right amount

There were some fun variations here that I hadn't seen before. I especially liked the 2-3 and 2-3-4 sudokus and the X-sums.

I felt that this test had harder classics and were under-valued compared to the Variants.This probably got accentuated by the fact that I just didn't solve the classics in the way they were meant to be solved.

I was doing the variants really well and suddenly I thought that I had completed all of the variants when actually I had completed only 4 of the 5 variant types . As a result,crossed over to the classics wherein I suffered a lot even at the 'hands' of a 2 pointer.In hindsight,I should have solved the 2-3-4 rather than persisting with the classics a lot.Got to submit a few classics in the dying moments and salvage some points.This test comes in the category of the hard sets like Evergreen(PR) and Maths(SM)

My favourites of the test are X-sums followed by skyscrapers.Really clean solve paths.Variants were really lovely and I enjoyed solving them a lot.Thanks for authoring the set Rishi.

nice outside variants, some new to me. A standard outside (1-2-3 outside for 9x9) would also have been highly desirable.

Had a few stumbles, but enjoyed the set.
Loved the 2-3-4 Outside 9x9

Nice test !

Thanks Rishi !

I think some classic puzzles in this test are harder than others test. Otherwise, enjoy the outside clues variants, thanks.

A good solid test - I couldn't quite get the last puzzle out in time sadly.

Strange.We have no contender finishing in the 90-100 range (so far).The Forbidden gap eh?!

100.6 and then a straight 12 points down directly to 88.6.Now, what are the odds of that happening ?!

I feel the Classic Sudokus are tougher than the variants, which unfortunately I spent a long time. Overall nicely constructed sudokus and a great challenge for all.
