Thanks for the nice test !

I really enjoyed !

My mistake was to think it would just be a small tournament with easy/medium sudokus, so I don't have to print the pdf (some cartridges of my printer are empty and I was too lazy to replace them), playing online should be ok. So I started the test while a bit tired and thinking it would just be relaxing time.

I'm not a big fan of sum frame sudoku, as I think it's globally always the same logic, it's impossible to have a real surprise with this variant.

On the contrary, I think group sum sudoku has big potential of being really interesting. I created my first group sum sudoku last year for the WSC swiss qualification and I think it's possible to create very nice group sum. One may think it's just about the same as killer sudoku, but I think some aspects are really different. And I must admit I haven't been disappointed during the test. Both 6*6 and 9*9 group sums were 10-stars sudokus. I think I was very efficient on the 6*6, I was quite fast at noticing the pairs 12 in rows 2 and 3. I had the beginning of the 9*9 quite fast, too. But unfortunately made a mistake, and had to start again. Then I eventually learnt a new trick on this 9*9 group sum sudoku. Very nice, thanks Rohan for this one !

Then came the equal product sudoku, and on the 9*9 I had hard regrets not having printing it. Not being able to write notes outside the grid was fatal for me. I made lot of very stupid mistakes by forgetting some possibilities for products many times while solving (it finally took me more than 30 minutes to solve it, haha !)

The only little critic I could make is that the tournament was perhaps a bit hard for the intended purpose. I was a bit surprised, but it was a very nice surprise for me ;)

Thanks Fred. I'm glad you enjoyed.
I agree the test is a little hard, and that was intended.

I really loved the 6x6 Group Sum, it was my personal favourite of the set. The 9x9 Group Sum has a very narrow solving path, but logical.
The Equal Product 9x9 is tricky. I think if you do your homework well, it is a Medium-difficulty sudoku. It uses a lot of deductions from the crosses.

I definitely agree. I solved it like a dilettante and had to face a lot of contradictions while solving because I was too lazy to really take it in a logical way, that's why I wasn't efficient on this one.

 How well did the variants represent the theme of the test ? variations represented the theme well
 What was your opinion of the distribution of easy/hard puzzles? Too many medium difficult puzzles
 What did you think about the puzzle quality of the test? Very nice
 Of the puzzles you solved/attempted, how well did the point values reflect the difficulty? Most puzzles were worth the right amount

How on earth are the small puzzles worth that many points? I solved quite a few of them quite a bit faster than I solved the classics.
