What happened to Globe and Mail Crossword?

The Globe and Mail Crossword hasn’t disappeared—it’s still part of the newspaper’s daily puzzle offering. The crossword coexists with Sudoku in the same Games section, giving readers access to both pencil-and-paper classics in one convenient location.

Current status

According to the Globe and Mail Help Centre, the crossword and other puzzles remain available on the Games page. Readers who remember when crosswords were a staple of the print edition will find the same experience translated to the online platform, with daily challenges across multiple formats.

• Online access through the Games page

Both puzzles live under the same umbrella on the Globe and Mail website, making it easy to switch between a crossword and Sudoku depending on your mood. The Games page serves as a one-stop destination for all pencil puzzles, including cryptic challenges for those looking for something beyond standard crosswords.

This coexistence gives you the freedom to vary your daily puzzle habit without switching platforms or losing momentum between puzzle types.

Is Sudoku high IQ?

Sudoku doesn’t measure IQ in the traditional sense, but it does engage cognitive skills associated with analytical thinking. The puzzle rewards pattern recognition, logical deduction, and systematic approaches—abilities that correlate with certain aspects of intelligence without being a direct IQ proxy.

Link to intelligence

Research in cognitive psychology suggests that puzzle-solving activities like Sudoku can help maintain mental sharpness, particularly in pattern recognition and working memory. However, the relationship between puzzle performance and general intelligence is indirect. Strong Sudoku solvers typically excel at visualizing number relationships, but this skill doesn’t automatically translate to other cognitive domains measured by IQ tests.

• Sudoku engages pattern recognition skills
• Performance correlates with logical reasoning ability
• Not a direct measure of general intelligence

Sudoku solving ability and intelligence

What makes someone good at Sudoku isn’t raw intelligence alone—it’s patience, systematic thinking, and the willingness to methodically work through possibilities. Regular solvers develop these skills over time, making the puzzle as much about practice as innate ability.

The takeaway is that Sudoku strengthens specific mental muscles rather than serving as a general intelligence indicator, making it valuable for cognitive training regardless of your natural aptitude.

What kind of person is good at Sudoku?

Successful Sudoku solvers tend to share certain personality traits and cognitive preferences. Understanding these characteristics can help you recognize your own strengths and identify areas where you might need to adjust your solving approach.

Personality traits

The most dedicated Sudoku enthusiasts typically display patience, logical thinking, and comfort with methodical processes. They enjoy working through problems systematically rather than relying on intuition or guesswork. Perfectionists often excel because Sudoku demands precision—one wrong digit cascades through the entire grid.

• Patient and methodical approach
• Logical, systematic thinking
• Comfort with delayed gratification
• Attention to detail and precision

Skills required

Beyond personality, effective Sudoku solving relies on spatial reasoning, the ability to track multiple possibilities simultaneously, and the discipline to work through elimination methods without becoming frustrated. Memory plays a role too, as experienced solvers internalize common patterns and recognize them instantly.

This means anyone can develop Sudoku proficiency by cultivating patience and systematic habits—natural talent provides a head start, but consistent practice closes the gap.

What is the 45 rule in Sudoku?

The 45 rule is an advanced solving technique based on a fundamental property of Sudoku grids: every row, column, and 3×3 box must sum to exactly 45. This technique becomes particularly valuable when working through Hard-level puzzles like those published by the Globe and Mail.

Explanation of 45 rule

The 45 rule works by identifying how much of the required 45 has already been filled in a given row, column, or box. By subtracting known numbers from 45, you can determine which digits are missing and—crucially—which cells must contain them. This technique shines when a row or column has several filled cells, leaving only a few possibilities to calculate.

• Every row, column, and box must sum to 45
• Subtract known values from 45 to find missing digits
• Particularly useful for Hard-level puzzles

Related 159 rule

The 159 rule complements the 45 technique by focusing on digit position rather than sums. When a row contains 1 and 5, the 159 rule helps identify where 9 might logically go—or conversely, where it cannot be placed. This cross-referencing approach adds another layer to your solving toolkit.

For Globe and Mail Hard puzzles, solvers frequently encounter grid states that require these advanced techniques. The “A Fan of Sudoku” YouTube channel demonstrates Slice and Dice, Locked Candidates Pointing, and Hidden Block Pair methods—all designed to crack the most challenging grids the newspaper publishes.

This layered approach to solving means that mastering the 45 and 159 rules equips you with tools that transfer to virtually any challenging Sudoku you encounter.
