Lewis Logic
Brain games worth your time.
Puzzle-based apps that sharpen spelling, math, chess, and logic — built for curious kids and clever adults alike. No ads. No clutter. Just you and the next great challenge.
What We Make
We build small, focused brain-training apps that are easy to pick up and hard to put down. Each one is designed around a single idea: make thinking fun.
🔤 Spelling — Build vocabulary and word skills one puzzle at a time.
♟️ Solo Chess — Sharpen your strategy against thoughtfully crafted challenges, no opponent required.
➕ Math Equations — Train number sense and quick thinking, from playful to seriously tricky.
✨ …and more on the way — We're just getting started.

Kid-friendly, adult-tough. Gentle enough for young learners, deep enough to keep grown-ups guessing.

Learning that sticks. Every puzzle is a little workout for your brain.
About Us
Lewis Logic LLC is a family business — founded by a husband-and-wife team who love puzzles, learning, and building things together.
It started with a simple frustration: most "brain training" apps were cluttered with ads, locked behind subscriptions, or just plain dull. We knew there was a better way. So we decided to make the apps we wished existed — clean, clever games that respect your time and actually make you think.
Everything we build follows the same philosophy: simple to start, satisfying to master. Our games are designed to be enjoyed by the whole family. A child can learn their spelling words while a parent wrestles with a chess puzzle on the same couch — each challenged at their own level.
We're a small team with big ideas and a growing list of apps. Every puzzle we release is one we've played, tested, and loved ourselves. Thanks for being part of the journey.
