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.
