Nguyen Tai Duc, a student from the Hanoi-Amsterdam High School, has reached the semi-finals of the one-handed event in the first World Rubik’s Cube Championships held in Bangkok, Thailand, from October 14-16.

The tournament has attracted more than 300 players from 36 countries and territories around the world competing in 18 events including Rubik’s Cube 2x2 4x4, 5x5, 6x6 and 7x7, one-handed, blindfolded, with feet, Pyraminx, Megaminx and with the fewest moves.

The Vietnamese delegation to the event comprise four members from the Hanoi Rubik Club.

Rubik\'s Cube is a 3-D mechanical puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik.

In the classic Rubik\'s Cube, each of the cube’s six faces is made up of nine different coloured squares (traditionally white, red, blue, orange, green, and yellow). A pivot mechanism enables each face to turn independently so the colours can be mixing up.

The object of the game is to move the squares so that each face is one solid colour.
