Inspiration
We were inspired by classic sliding tile puzzles like the 8-puzzle and the daily image puzzles seen on platforms such as Bing and other gaming websites.
Our goal was to create a simple but addictive puzzle experience that works directly inside Reddit, so users can play instantly without leaving the app.
Sliding puzzles are timeless — they combine logic, patience, and quick thinking — which made it a perfect fit for the Reddit Daily Games ecosystem.
What it does
Slide Puzzle is an interactive sliding tile game where players must rearrange scrambled image tiles to restore the original picture.
Players can:
- Start a new puzzle instantly
- Slide tiles into the empty space
- Track their moves and time
- Reset and replay for a better score
- Enjoy a clean Reddit-native game interface
How we built it
We built Slide Puzzle using Reddit’s Devvit Games platform.
The game logic includes:
- Dynamic tile grid generation (4×4)
- Random but solvable shuffling
- Smooth tile movement interactions
- Win detection when the puzzle is completed
- A simple UI with start, reset, and stats display
We also designed custom branding, including a logo and loader screen, to make the game feel polished and ready for Reddit players.
Challenges we faced
Some of the main challenges were:
- Implementing correct sliding mechanics inside a Reddit embedded environment
- Ensuring the shuffle always produces a solvable puzzle
- Designing a responsive UI that works well in Reddit’s simulator
- Integrating game flow smoothly (start screen → gameplay → reset)
What we learned
This project helped us learn:
- How to build and deploy games using Devvit
- Best practices for interactive Reddit experiences
- Managing UI + game logic together in a constrained environment
- Creating daily-game style content for subreddit communities
