Editorial interest 72/100 Selection signal · not a rating of the site

An early-stage learning-and-play site with chess against an on-device opponent, daily puzzles, wordplay, and public-domain reading.

Landing page captured for the 2026-09-26 issue.

For: Adults, families, and chess clubs
Worth noticing: The chess game runs against an on-device opponent; the page says no account is needed and nothing is sent anywhere.

Field notes

The chess path offers side and level selection, with a one-tap look-back and a rating described as gentle. The page also lists a daily puzzle, historical chess games, a word-making activity, and public-domain reading on chess, puzzles, and logic. A human-like opponent and a code-joined online room are described as future additions, not current features.
