Expert guidelines & clinical citations
Large print puzzles offer therapeutic mental stimulation when designed to clinical accessibility standards.
Our layout philosophy aligns with national recommendations for cognitive wellness and low-vision accommodation:
“Reading materials designed for older adults and individuals with reduced visual acuity should feature high-contrast print of at least 18 points, generous letter spacing, and uncluttered layouts to minimize ocular fatigue and promote continued reading independence.”
“Engaging regularly in cognitively stimulating leisure activities—such as solving word puzzles, reading, and brain games—helps exercise cognitive reserve, supports verbal memory, and maintains neurological processing speed as adults age.”

Large print design
The difficult board uses an 18 by 18 grid, large letters, no countdown, and print and answer pages that remain tied to the same layout.
Start with the word list, choose one word, and scan the grid for
either end of that word. Tap one end, then tap the other end. The
page avoids drag-only controls, timers, score penalties, and account
gates.
Print and answer support
Use this page when a regular adult printable feels too quick, but a tiny-letter puzzle would be uncomfortable or impractical.
