Mora Jai Box Simulator

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.

Simulator

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).
    • See Blueprint - AquariumYellow Box 3, Blueprint - Pool RoomRed Box 3, Blueprint - FurnaceBlue Box 2, and Blueprint - BallroomBlue Box 3 for examples.

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.
