Mora Jai is a fan-made puzzle game inspired by Blue Prince and its iconic Mora Jai puzzle boxes. While preserving the original mechanics, this project introduces a distinct visual style influenced by Japanese aesthetics, combining minimalism, color symbolism, and a serene atmosphere.

Mora Jai revolves around a 3×3 puzzle grid where each tile has a color and triggers a specific effect when activated. The challenge is to understand the interactions and solve increasingly complex puzzles.
- Click tiles to activate their effects.
- Match the four corner tiles to the target colors to open the box.
- Plan your moves carefully. Tiles can affect themselves and nearby tiles.
- Solve the puzzle to unlock seasonal rewards and progress through levels.
The tile moves are the same as those in Blue Prince:
| Color | Effect |
|---|---|
 |
Has no effect |
 |
Turns gray, toggles adjacent tiles white/gray |
 |
Shifts the row to the right |
 |
Turns black tiles red and white tiles black |
 |
Rotates adjacent and diagonal tiles |
 |
Changes to the majority color among adjacent tiles |
 |
Moves upward |
 |
Swaps with the opposite tile |
 |
Mimics the center tile |
 |
Moves downward |
Understanding how certain tiles interact (like Blue and Red) can help you chain effects and solve puzzles faster.
Completing puzzles unlocks season-themed illustrations.
Players can collect up to 10 illustrations per season, totaling 40 unique rewards.
Reward Examples:
| Spring | Summer | Autumn | Winter |

Mora Jai is developed with React, TypeScript, and Vite for fast and maintainable development.
To design the 40 levels, a mix of Breadth-First Search (BFS) algorithms and manual selection was used, ensuring each puzzle is unique, challenging, and solvable while demonstrating the game's mechanics.
