About xsplayground

What is this place?

xsplayground is a playground for quick mini games and small tools that come in handy in everyday life. Every app opens right in your browser with no install and no sign-up, and everything is free to use without limits.

Four languages — Korean, English, Japanese, and Chinese — and light and dark themes are supported. The same address works on your phone, tablet, and desktop.

The apps so far

3D Maze Game — explore mazes built from one short code, in character view or overhead view. Difficulty runs from level 1 to 20, every maze has its own rankings plus a weekly challenge, and any maze prints on a single A4 sheet as a paper puzzle.

Wheel Spinner — add your options and spin to pick one fairly. Great for choosing presenters, deciding lunch, and running raffles; share the exact wheel via link or QR, or print a cut-out A4 paper spinner.

Sudoku — solve freshly generated unique-solution puzzles in your browser. Classic 9×9 plus kids' 4×4 and 6×6, five difficulty levels graded by solving technique, and A4 printing with an answer page included.

Word Search — paste your own word list to build a word search puzzle in seconds. Grids come in English, Korean, and Japanese; print on A4 with an answer sheet, or share by link or QR so others solve the same puzzle in the browser.

Nonogram — fill cells from the number clues on each row and column until a hidden pattern appears. From starter 5×5 to large 20×20, every puzzle is verified to be solvable by pure logic with no guessing, plus picture puzzles that reveal a drawing, a weekly challenge, and A4 printing with an answer sheet.

How it's built

The same code is always the same game — mazes and sudoku puzzles are rebuilt entirely from a short code, and a wheel's item list travels whole inside its link. One link puts you and a friend on an identical board, and the same code reopens that board even years later.

Pages are kept light, with no external fonts or heavy assets. Even the sound effects are synthesized in the browser instead of loaded from files. That's why everything opens fast, with no strain even on a slow connection.

Records stay in the browser you're using by default. Only when you put your name on the global ranking are your nickname and record stored on a server. The details are laid out in the privacy policy.

Beyond the screen — print and QR

Every app supports A4 printing. Maze sheets, sudoku, word search, and nonogram sheets with answer pages, and cut-out paper spinners — with one printer, you can play without a screen at all.

Every printout carries a QR code. Scan it and that exact board opens online, so you can move freely between paper and screen.
