What is this place?
xsplayground brings together short games and useful little tools. Every app is designed deterministically, so the same code opens the same board again and can be shared by link or QR code. That keeps a shared puzzle fair and easy to revisit.
The site comes in four languages (Korean, English, Japanese, and Chinese) and supports light and dark themes. 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, whether you're choosing presenters, deciding lunch, or 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 can solve the same puzzle in the browser.
- Nonogram
- fill cells from the number clues on each row and column until a hidden pattern appears. Every puzzle, from starter 5×5 to large 20×20, is verified to be solvable by pure logic with no guessing. The app also has picture puzzles that reveal a drawing, a weekly challenge, and A4 printing with an answer sheet.
- Endless Drift
- a purely contemplative ambient app that floats through one continuous night world, from the deep sea to outer space. There is no score and no timer; leave it on and it drifts by itself, with procedurally generated sound that shifts with altitude. You can share any view you love exactly as it is with a single code or QR.
How it's built
The same code always produces 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
Five apps support A4 printing: maze, wheel spinner, sudoku, word search, and nonogram. Print maze sheets, puzzles with answer pages, or a cut-out paper spinner to keep playing away from the screen.
Every printout carries a QR code. Scan it and that exact board opens online, so you can move freely between paper and screen.
