Happy New Year solvers! The 2021 3D crossword puzzles will be made available progressively throughout the year. The deadline to enter the prize draw for regular monthly puzzles will be the last day of that month. Extra puzzles will be added from time to time and will have later, mid-month deadlines.

Hints and tips for each puzzle will be published sometime in the middle of each month. Subscribe to the Hints & Tips newsletter to receive them by email.

Solvers who buy the calendar and correctly solve 12 puzzles by the due date each month will be eligible to enter our annual tie-break competition for the 2021 3D Crosswords World Championship. If you have been entering the monthly competitions, you can check your progress towards the tie-break qualification.

2021 Puzzle of the Year

You are invited to vote for your favourite puzzle of the year from the 13 puzzles featured in the Calendar (the extra puzzle was Sirius and Enigmatist’s tribute to Araucaria) plus the August extra puzzle.

You are allowed to allocate a total of 3 votes. All 3 may be allocated to one puzzle, or two votes to one puzzle and a single vote to a second puzzle, or one vote each to three puzzles.

All our solvers and contributors are encouraged to vote. The only rule is that setters and designers don’t vote for their own creations, magnificent as these might be.
