1 of 3 alternatives have vague differentiators
Why we flagged this
- The New York Times Crossword: substantive — Names a specific scope differentiator: free access to 15x15 grids plus two named game types. - USA Today Crossword: vague — 'Clean interface' is a hand-wave without specifying what makes it cleaner; mentioning the same games as others doesn't differentiate. - Washington Post Crossword: substantive — Names specific features: difficulty tiers for segmentation and explanations for post-solve learning, both concrete axes.
