Jakub Ondroušek has beaten the world recordWed, 06/16/2010 - 11:41 - AdminFast Sudoku solving world record fulfilling given conditions was held so far by Belgian Vincent Bertrand. His time was 3 minutes 6 seconds. This achievement was reached at the World Sudoku Championship 2009 in Žilina, Slovakia and is written in the Guinness World Records.

On Saturday June 12, 2010 there was a traditional the 'Dobrý den' Agency's International Festival of Records and Curiosities in Pelhřimov. Three worlds Sudoku champions Jana Tylová, from Most, and Honza Krtek Novotný and Jakub Ondroušek, members of the Sudoku club Kabrňáci from Brno, pitted their strength there. It was mainly about setting the Czech national fast Sudoku solving record and then about its improving. At first there was warming up at 'easy newspaper Sudoku puzzle' and after that our world champions had two attempts with two Sudoku puzzles created by fivefold world puzzle champion Robert Babilon.

Jakub Ondroušek settled the Czech record of 2.53 minutesin the he first attempt started by the legendary runner and world record holder Jarmila Kratochvílová and under 'Dobrý den' Agency's scrutiny.

The patron of the second attempt was sevenfold Olympic Games winner - a gymnast Věra Čáslavská. In this attempt Jakub Ondroušek beat his previous performance and improved the Czech record: Babilon's master Sudoku was solved in unbelievable short time of 1 minute 25 seconds. So, Bertrand's world record was beaten and markedly improved. And because Krtek's time in the second attempt was 2:16 min, this means that the world record was beaten three times in Pelhřimov.

The fight was really exciting because Krtek always had the great start, whereas Kuba was excellent in the end. And the end was the crucial moment. Jana Tylová chimed in well, but smashing hot weather did its 'fair whack'.

Great thanks to all people involved for their participation in the festival, for their good representation of SČHAK, and for the fact they were able to hold the audience and to give outstanding performances.
