About Daily Grid

Daily Grid is built and run by Zachary Zimmerman, an independent software engineer and daily puzzle player. Every part of the site — the eleven games, the puzzle generators, the leaderboards, and the iOS app (rated 5.0 out of 5 on the App Store) — is designed and coded by one person.

"I'm a daily puzzle player and a software engineer — Daily Grid started as a fun side project and turned into something even I play every day. I love building the games as much as playing them, and that's the bar: every puzzle has to be something I'd want to come back to tomorrow."

Zachary Zimmerman, founder

The idea is simple: one small ritual of clear thinking, every day. Daily Grid gives you eleven free logic puzzles in your browser each day — no account, no download, no paywall — with a fresh handcrafted set at midnight Pacific Time. Solve at your own pace, keep a streak going, race friends for daily medals, or just enjoy a few quiet minutes of deduction with your coffee.

Every Daily Grid puzzle is designed to be solvable by logic alone — no guessing required. Difficulty is tuned so a puzzle feels solvable on your lunch break but still makes you think. The interfaces stay deliberately calm: no ads, no pressure from the clock unless you want to race for medals, and no clutter between you and the grid.
