The event was carried out in March 2019 and began at 12.00pm. Each participant was given one of the limited-edition pens of IEEE PES UNITEN SB. The time taken by each participant to finish the challenge was recorded by the person in charge. There were 3 sets of sudoku questions. The challenge ended at 4 pm on the same day. We then calculated the number of correct answers. Since more than 5 participants answered all the sudoku correctly, time was taken into account. The fastest 5 participants who finished the sudoku with all answers were correct will be chosen as the winner. At the end of the program at 5.00pm, we called all the winners for the prize giving ceremony. The prizes were given by Dr. Zaipatimah Bt. Ali (Club Advisor).
