The classic games will feature as part of the annual board game festival later this month.
First launched in 1997, the Mind Sports Olympiad is an international event with different board game competitions. Its aim was to create an Olympics of the mind, awarding gold, silver and bronze medals for each event.
John Adams, UK distributor of Rummikub and Othello, will be on hand to encourage eager gamers to share their experiences and photos by following new social media brand channels that have recently launched.
There are also opportunities to learn new games and play for fun in the Learn to Play room. As well as Rummikub and Othello, John Adams will be showcasing its new table top strategy game Tetris Dual based on the popular classic video game.
The 21st Mind Sports Olympiad will take place between 20th and 28th August at JW3, 341-351 Finchley Road, London NW3 6ET.
