Clear yourself a 2½ hour window at a time of your choosing between noon on Friday 26th June and 2am on Tuesday 30th June. (Both times are quoted as British Summer Time; you can start at any point up to 11:30pm on Monday 29th June, so you have 3½ days.) During that time, you aim to score as many points as possible by solving the 28 puzzles, submitting your answers on a web form as you go.
The puzzles are a mixture of logic puzzles, arithmetic puzzles and word puzzles. Go to the contest page and download the instruction booklet which tells you what sorts of puzzles that there are on offer this year. Maybe you can find ways to practice some of them, or puzzles like the ones in the contest, but some are original and working out how to solve them is part of the fun.
There are plenty of online puzzle contests in the calendar; however, the UK Puzzle Championship has been my favourite or second favourite of the year for several years running. It’s deliberately accessible, so as many people as possible can enjoy the thrill of proving to themselves that they really can solve puzzles that looked impossible at first. Normally I finish about three or four places from the bottom (which used to be good when there were only half a dozen UK entrants at the start, but these days there are something like two dozen, so it’s rather less good) but even so I have had a great deal of fun along the way – and you can too, no matter how little you rate your own puzzle solving skills.
Why does your country need you? Well, the UK Puzzle Association uses this as a qualifying tournament for its team at the World Puzzle Championship, which this year will be held in Sofia in Bulgaria in mid-October. Last year’s event was in Croydon here in the UK; this site covered the event extensively. Opportunities to represent your country in meaningful global competition come rarely; puzzle fans, there are no better ones!
