Made quietly, one slide at a time
Slide Puzzle is a calm little app for one of the oldest, most satisfying puzzles there is — sliding numbered or pictured tiles into place. It's made by two people who like building small, unhurried apps together.
Who we are
We're not a company or a big studio — just two people who make small, calm apps together, and Slide Puzzle is one of them. We build the sort of things we'd want to use ourselves: gentle, uncluttered and happy to work offline. No accounts, no ads, no streaks nagging you to come back — just a board, a few tiles, and a quiet minute to solve it.
The two of us are Nadya Yashchuk and Ivan Lukichev, and we handle everything ourselves — design, development and support. We work remotely, and our apps are officially published as a small sole proprietorship registered in Austria; the formal details live in our Impressum. Because it's just the two of us, every release stays personal — we choose what to build, answer our own email, and shape each update around what players actually ask for.
We brought Slide Puzzle to the App Store and Google Play in 2026, and we're only getting started — new covers, sizes, tools and little improvements land all the time.
What Slide Puzzle does
Our flagship app, Slide Puzzle, turns the classic 15-puzzle into something you'll actually want to open. Pick from a gallery of photographic covers, choose a board size from 3×3 up, or drop in a photo of your own and slide it back into place. It works fully offline, so you can play on a plane, on the sofa, or anywhere the day takes you.
- Real photos, not just numbers: a library of covers, or slide a picture of your own.
- Four sizes: from a gentle 3×3 up to a proper brain-stretcher.
- Calm by design: no accounts, no ads, no streaks — just the puzzle.
- Works offline: once installed, it's yours to play without a connection.
Free tools on the web
You don't even need to install anything to start. Right here on the site we offer free, no-sign-up tools that run entirely in your browser: a sliding puzzle solver that finds the shortest solution for any 3×3 to 6×6 board, dedicated 15-puzzle and 8-puzzle solvers, a picture solver that reads a screenshot, and even a Brawl Stars pyramid helper. We also keep a growing library of guides — from how to solve the 15 puzzle to the parity proof behind the impossible ones.
Our other apps
Slide Puzzle is part of a small family of quiet apps. If you love the solvers, there's also Puzzle Slide Solver — the same engine as a dedicated iPhone app, so you can solve a board straight from a photo on the go. We build every app with the same promise: simple, friendly, and made to relax rather than distract.
