The Idea Behind the Project
The goal was to create a self-contained, portable version of the 15-tile puzzle that could be played anywhere without the need for an external power source. Unlike the traditional cardboard or plastic versions, this one features an electronic display, physical buttons for movement, and a rechargeable battery.
Key Features
1. Four-Direction Control
The game is played using four directional buttons, allowing smooth movement of the empty space to shift tiles into place. The tactile feedback makes the experience more engaging compared to touch screens.
2. USB-C Charging
To keep up with modern standards, the device includes a USB-C port for charging. This ensures convenience and compatibility with most chargers available today.
3. Rechargeable Battery
A built-in rechargeable battery powers the device, making it truly portable. With efficient power management, the game can run for extended periods on a single charge.
4. Compact and Durable Design
Designed with portability in mind, the puzzle game is compact enough to fit in a pocket while being sturdy enough to withstand everyday use.
The Development Process
Hardware Choices
I used a small LCD or OLED display to render the puzzle visually, ensuring a crisp and clear appearance. The buttons were chosen for their durability and responsiveness, providing satisfying clicks with every press.
The internal circuitry was designed around a low-power microcontroller to optimize battery life. A small Li-ion or Li-polymer battery was integrated, with charging handled via the USB-C interface.
Software and Game Logic
The puzzle logic was implemented to ensure randomized, solvable tile configurations. The interface is simple but effective, providing clear visual feedback on tile movements.
Final Thoughts
Building this 15-tile puzzle game was a rewarding experience. Combining classic gameplay with modern technology resulted in a fun, portable device that brings nostalgia with a contemporary twist. Whether you're looking for a quick brain teaser or a competitive challenge, this electronic version of the timeless puzzle is a perfect companion.
