About Daily Grid

Daily Grid is built and run by Zachary Zimmerman, an independent software engineer and daily puzzle player. One person designs and codes the twelve games, puzzle generators, leaderboards, achievements, and the separate iOS app.

"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, so I make sure every puzzle is something I'd want to come back to tomorrow (and I always do!)."

Zachary Zimmerman, founder

The idea is simple: one small ritual of clear thinking, every day. Daily Grid gives you twelve free logic puzzles in your browser each day. No account, download, or paywall is required. A fresh set of original puzzles arrives at midnight Pacific Time. Solve at your own pace, keep a streak going, race friends for daily medals, unlock achievements and cosmetics, 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.
