A good word-grid game is not only a dictionary wrapped around a square of letters. The interesting design work happens in the feedback loop: how a player scans the board, tests a path, understands a miss, and returns for another attempt without being pushed into an account or a leaderboard.
I recently used Squaredle 2 as a small case study for this kind of browser-first practice experience. It is an independent word-grid project with Daily, Express, and Unlimited modes, and it keeps progress in the browser instead of requiring a sign-up.
1. Make the path rule visible
Adjacent-letter games usually allow eight directions while preventing one tile from being reused inside the same word. That sounds simple, but the interface has to explain it through behavior.
A useful implementation keeps the selected path visible, rejects a repeated tile immediately, and gives the same result whether the player drags, taps, or types. The visible path is not decoration: it is the proof that the game understood the player's intent.
