The Guardian published Sudoku puzzle number 7420 on 17 August 2026, rated as 'Easy' difficulty. This puzzle is part of the newspaper's daily brain-teaser series, designed to be accessible to solvers of all skill levels, from beginners to seasoned enthusiasts. With a 9x9 grid, the goal is to fill each row, column, and 3x3 box with the numbers 1 through 9 without repetition.
How to Approach the Easy Sudoku
For those new to Sudoku, the 'Easy' rating means that the puzzle can be solved using basic scanning techniques without advanced strategies like X-Wing or Swordfish. Start by looking for rows, columns, or boxes that have the most numbers already filled in—these 'gimmes' often reveal immediate placements. For instance, if a row has eight numbers, the missing one is straightforward to determine.
Another beginner-friendly method is 'cross-hatching': focus on a single number (say, 1) and see which rows and columns already contain it. By eliminating those, you can pinpoint where the number must go in each box. This systematic approach reduces guesswork and builds confidence.
Tips for Completing the Grid
When you're stuck, revisit each 3x3 box and check for numbers that appear only once in a row or column. Also, pencil in possible candidates for empty cells—lightly writing small numbers in the corner of each cell helps track options. For an 'Easy' puzzle, you rarely need to make more than a few logical deductions at a time.
If you prefer digital solving, many online Sudoku solvers allow you to input the given numbers and check your progress, but the Guardian encourages solving on paper for the full mental workout. The puzzle is available on the Guardian's website and in the print edition, with the solution typically published the following day.
Why Sudoku Remains Popular
Sudoku has been a staple of newspapers since its global boom in the mid-2000s, and the Guardian's version is known for its quality and variety of difficulty levels. The 'Easy' tier is perfect for commuters, coffee breaks, or anyone looking to unwind with a satisfying logic puzzle. According to puzzle editors, regular solving can improve memory and concentration, making it a worthwhile daily habit.
Whether you're a first-timer or a returning solver, Sudoku 7420 offers a pleasant challenge. Grab a pencil, print the grid, and enjoy the satisfaction of completing it. If you get stuck, remember that every puzzle is solvable with patience and careful elimination.
