Mora Jai Box
A Mora Jai Box is a lock box that involves solving a 3x3 grid of colored tiles. Each color has a unique behavior (see rules). They are originally found in the puzzle/adventure game Blue Prince, but are interesting to analyze on their own.
Warning: leave Spoiler Mode turned off if you’re still playing Blue Prince—it will reveal information relevant to endgame and post-endgame puzzles.

Rules
- To Solve: Press all 4 outer buttons after the corner tiles’ colors match the target color
- To Reset: Press any outer button that does NOT match its corresponding corner tile
- Tile Behavior:
- ■ Gray does nothing.
- ■ White causes adjacent white tiles (and itself) to turn gray. Adjacent gray tiles turn white.
- ■ Violet swaps with the tile below it.
- ■ Yellow swaps with the tile above it.
- ■ Green swaps positions with the tile opposite it.
- ■ Black shifts its row to the right.
- ■ Red causes every black tile to turn red, and every white tile to turn black.
- ■ Pink rotates all the tiles surrounding it clockwise.
- ■ If a majority of adjacent tiles are the same color, orange changes to match that color.
- ■ Blue mimics the behavior of whichever tile is in the center (with some quirks).

Challenge Puzzles
Based on computer analysis, I included several challenge puzzles that are not found in Blue Prince. The list is curated from a large set of puzzles with lengthy solutions, and arranged in order of perceived difficulty.
Challenge - Longest
technically has the longest solution, requiring a minimum of 84 moves to solve. Challenge - Yellow
requires fewer moves, but I found it to be the most difficult.
See Mora Jai Box Solution Space Analysis for details on how this list was developed.
