24HPC 2019

As in 3 years ago, we gathered to solve puzzles on April 29th - 30th. 15 people joined in, so we set 2 places - thanks to Hideaki and Taro.
The following includes my results, top Japanese score and short comments.

Round 1 1000 (-5 minutes)
Spy Battleships is funny as usual, and I am glad to see interesting  Figure Doppelblock. Pyramids were done by a lot of trial

Round 2 875
Left: Minesweeper
Error: Suguru (1 cell)
Nice theme again. Most of the time was spent on Minesweeper, but in vain.

Round 3 1000 (-15 minutes)
There were some strange types. Halloween caused some counting troubles but still have good logic, and Knights in Pentarmour was rational as a result.

Round 4 1000 (-34 minutes)
Comfortable round. The rule of Nagareru is different from the original version - the path had to go straight on arrows - but I cannot say which rule fit better.

Round 5 855 (Japanese best: 1000 by Kota)
Left: Sudoku, Magnets Kropki, Scrabble Kropki
I erased Skyscrapers Kropki 3 times or so, and simply lost time to see some puzzles. Magnets Kropki has quite skewed moves.

Round 6 650 (Japanese best: 1000 by Kota)
Left: Spiral Galaxies 1
Error: Double Kakuro 1 (1 cell brank), 2 (1 cell wrong)
I spent much time on two Spiral Galaxies. And only 2 cell costed me 220 points!

Round 7 920 (-26 minutes, but with an error. Japanese best: 940 by Tomoya, also with an error)
Error: Ham Sandwich (1 additional ham - gluttony!)
Many unknown types, but luckily they caused less trouble. I am happy to resolve Instructionless rule.

Round 8 970
Left: Ayda Diagonal
1 more minute needed to finish. Main cause was probably the last combination grid. Liar Shikaku has 2 solutions.

Round 9 885
Left: Surplus Doubleblock, Cascade Snake
Error: Virtual Skyscrapers (error on marking circles)
Hard round, as easily expected. I do not know exactly but I heard that there are many puzzles with multiple solutions. Most of the rules are difficult to grasp, but some of them have good aspects.

Round 10 1000 (-14 minutes)
Crazy round, and I ran crazily. So I could not see the nice theme well during the round. I heard that Pentacles 6 has multiple solutions.

Round 11 630
Left: Odd Yajisan-Kazusan, Even Yajisan-Kazusan, Equality Nurikabe, Intersections Scrabble, Liar Fillomino, Perspective Skyscrapers, Nurikabe Mashup Quadrants
Error: Alcove Tapa
Quite tough round, and thus sleeping round for some players. One of my bad moves was that wasting on Odd Yajisan-Kazusan in the beginning. Puzzles are so cool, with some dual grids. Intersections Scrabble was the only one puzzle no Japanese solved throughout the all 14 rounds.

Round 12 830
Left: Hidato 2, Irregular Starbattle 1, 2, Japanese Sums 1, 2, LITS+ 2
Funny theme. Simply I lacked the power, or stuck on high Oasis and Pentominoes.

Round 13 790
Left: Domino Skyscrapers, Number Tables 2, Arrows 1, Diagonal Irregular Sudoku, Second Letter Seen
The round we purely lost to Nikola. Poker did not work for a while, and I feel I am not accustomed to Champions League type yet.

Round 14 900 (-10 minutes, but with errors)
Error: Coralfinder (2 cells switch), Tapa (1 cell brank)
Collapse in the end again. I wonder how to change this tendency.... Puzzles were solved nicely, I especially like the last matchmaker.

I did not solve all rounds continuously last year, so I felt rather fresh. And I am seeking for a chance to go to Budapest again.
