Inspiration

The project started as an exploration of what a daily puzzle could look like if it stayed small and focused. Classic sliding-tile puzzles are immediately understandable, while logic games like Mastermind introduce deduction and uncertainty.

What it does

Slide Master is a daily sliding-tile logic puzzle. The board behaves like a traditional sliding-tile puzzle, but all tiles are visually identical. There are no numbers or unique tile visuals to indicate where a tile belongs.

Instead, after each move, the game provides feedback:

• tiles in the correct position
• tiles in the correct row or column but in the wrong position
• tiles in the wrong place

The objective is to solve the board in the fewest moves possible. Every day, all players receive the same puzzle.

How we built it

The game was built in GDevelop using an event-based architecture. Tile movement follows standard sliding-tile rules.

Challenges we ran into

The main challenges included:

• Handling daily resets without interrupting active gameplay
• Learning and working with Devvit for the Reddit platform

Accomplishments that we're proud of

• Designing a puzzle that feels familiar but requires a different way of thinking

What we learned

• How to generate a shared DailySeed so everyone gets the same puzzle each day
• How to submit and host a playable game on Reddit
• That Reddit actually has a game platform — I honestly thought it was just for discussions

What's next for Slide Master

If time and resources allow, future improvements would include:

• A more polished leaderboard UI
• Additional board sizes or difficulty modes
