Developed in 2024 by Emanuel Boboiu and Andrei Mischie, and updated in October 2025 by Emanuel Boboiu and Nelu Cîmpean, the game is optimized for seamless performance on mobile devices and supports screen readers, ensuring accessibility for all players.
Gameplay
15 Puzzle features grids with 9, 16, or 25 cells, offering varying levels of difficulty to suit all skill levels. Your objective is to arrange the numbered tiles in ascending order within the grid. For example, in a 4×4 grid, you'll need to arrange the numbers from 1 to 15.
The grid contains one empty cell, allowing you to slide adjacent tiles into the empty space. To move a tile, simply tap, click, or use gestures. If the tile is adjacent to the empty cell, it will slide into the empty space.
Continue sliding the tiles strategically until you've arranged them in the correct order, ensuring the empty cell ends up in the bottom-right corner.
This game was created to demonstrate how a single codebase can power a game across major platforms while maintaining excellent accessibility.
