UK Open Puzzle & Sudoku tournaments 2018

UK Open 2018

This year's UK Open tournaments will take place over the weekend 3-4 March 2018, at the Hallmark Croydon Aerodrome Hotel

This growing annual event is a must for anyone with an interest in puzzles or sudoku. Although there will be a competition element to the weekend, more importantly it is the annual opportunity to mix with others sharing your interests in a relaxing environment.

For the competitively minded, there will be competitions. Each competition will be made up of manageable rounds, much like a mini world championship. There will be a variety of prizes on offer, including best newcomer, and best overseas competitor for each event.

These events will be used as part of the selection process for the UK teams, where the top 2 British competitors in each event will earn a place on the A-team to represent the UK at the 2018 World Sudoku Championships (WSC) or World Puzzle Championship (WPC) that will be held this year in Prague, Czech Republic, 4-11 November 2018. (Official Championship website)

Everyone is welcome to participate, including overseas competitors. Children under the age of 16 must be accompanied by a parent or guardian.

Sat 3rd March:
10:30am - 3:00pm Sudoku tournament
4:00pm - 6:30pm Puzzle tournament part 1
Sun 4th March:

If a puzzle packed weekend, meeting up with like-minded people, in the company of the UK's top solvers, appeals to you, then these are the events for you. Spaces are limited, so make sure you register early to reserve your place.

The venue

Hallmark Croydon Aerodrome Hotel

Hallmark Croydon Aerodrome Hotel

"Our hotel opened in 1928 to serve passengers flying in and out of Croydon Aerodrome and over the years, we’ve welcomed many famous footsteps to our aviation landmark. Amy Johnson embarked on her record-breaking flight to Australia from here and Charles Lindbergh arrived in his Spirit of St Louis single-engine plane."

"Of course the Hallmark Hotel London Croydon Aerodrome has adapted to changing times and now has 110 stylish, contemporary bedrooms with super-fast, reliable WiFi throughout and the business guest essentials such as multi-channel flat screen TV, 24-hour room service, plenty of desk space and enough USB charging ports to juice up the laptop and keep the phone and tablet alive during the night."

Located close to East Croydon train station, it takes just 15min to Central London & Gatwick Airport, with many tourist attractions nearby.
