Drag the fragments home and watch them snap into place. Nine puzzle families across 2D, 2.5D and 3D — one tap and you're solving.
The same forgiving drag-and-snap, reimagined across every dimension. Each family owns a colour, so you always know where you are.
Jigsaw, Grid, Shapes, Hex, Triangle, Pipes and Nonogram — slide, rotate and fit pieces into the board.
A cube whose six faces are puzzles. Fly in, tile a face, and watch the whole solid come together.
Fill a voxel box with polycube pieces. Orbit, line them up, and let them rotate to fit.
From a two-minute daily to an endless journey — and, when you're ready, the whole table lights up.
An endless, ever-harder path through themed chapters, with boss levels and reward stops.
From the startFive fresh puzzles every day that reset at midnight — build a streak on the global board.
From the startFree play — pick any of the nine types, any level, or drop in your own seed.
Unlocks at level 3900 fixed, seeded levels — 100 of every type, laid out chapter by chapter.
Unlocks at level 5Live rolling events — race the clock across twenty games for a place on the board.
Unlocks at level 8Challenge a friend with a code, or go head-to-head live over the same five puzzles.
Unlocks at level 8Every level opens with the fragments loose around the board — and a solution the game already knows.
Slide a fragment near its home and it eases in with a satisfying little spring. Miss, and nothing breaks.
Fill the shape to win. Faster and hint-free means three stars — and a burst of confetti to match.
Seven flat families, one foldable cube, one free-space box — each with its own feel.
Fragment Builder is a free, browser-based puzzle collection. Every level starts as a shape broken into fragments; you drag each piece back to its place and it snaps in with a satisfying spring — across nine puzzle families in 2D, 2.5D and 3D, through six game modes and endless, always-solvable levels.
Yes. Fragment Builder is free to play — in your browser and as an Android app on Google Play — with no sign-up for the single-player game. The browser version shows no ads at all. The Android app is supported by ads that never appear mid-puzzle: none during the first 50 Journey levels, an occasional short ad between levels after that, and optional rewarded videos for extra hints, moves and rewards.
Fragment Builder has nine puzzle families — Jigsaw, Grid, Shapes, Hex, Triangle, Pipes, Nonogram, Grid Cube and Grid Box. Levels are endless and procedurally generated, plus there are 900 fixed Challenge levels, 100 for each puzzle family.
Fragment Builder plays in any desktop or mobile web browser, installs as an offline-capable app (PWA), and is available as an Android app on Google Play. An iOS version is coming soon.
No. The entire single-player game works with no account, and your progress is saved on your device. Without signing in you still appear on the leaderboards as a guest. Signing in (Google or email) adds cloud save across devices, lets you choose your own nickname, and keeps your progress if you change phones.
Yes. Once installed as a Progressive Web App (PWA), Fragment Builder works without an internet connection. Only the optional online features need connectivity.
Fragment Builder is made by Adnan Vehabović, an independent developer based in Sarajevo, Bosnia and Herzegovina, using React, Vite and three.js.
