Persona 5 The Phantom X Floor Puzzle Solutions

Persona 5 The Phantom X features several “floor puzzles” in Kiuchi’s Palace, mainly in the Club floors and Exhibition Hall. Here are the key ones and their solutions so you can clear them quickly.

Club 2F Tile Thumbs Puzzles

On Club 2F you’ll find three rooms with floor grids and a board showing thumbs-up/down/left icons. Each thumb pattern corresponds to how you should fill the tiles.​

• Thumbs-left room:
  • Solution: Mirror the half-completed pattern diagonally across the grid. Fill in tiles so the pattern looks symmetrical along the main diagonal.​
• Thumbs-down room:
  • Solution: Fill all tiles except the two squares directly adjacent to the bottom-right corner.​
• Thumbs-up room:
  • Solution: Fill every tile except:
    • Top-right corner.
    • Bottom-left corner.
    • The tile directly below the top-left corner.​

Stepping on the wrong tiles resets the grid, so if you misstep, just walk off and try again.

Club 3F Thumb-Path Floor Puzzle

On Club 3F there is a corridor with electrified tiles and a notice board showing a series of thumbs. This defines an exact walking route to disable the barrier.​

Use Third Eye to see the thumb sequence on the board, then follow this order on the floor:​

• First sequence: Thumb Left → Thumb Up → Thumb Down.
• Second sequence (after the new room opens): Down → Right → Up.
• Third sequence: Right → Down → Left.
• Final sequence: Right → Left → Up → Down.​

Walking in these directions across the tiles in order opens all doors and removes the electric barrier leading to the chest and exit.

Club 3F Red vs Pink Tile Final Puzzle

The final big floor puzzle in Kiuchi’s Palace 3F uses two small grids at opposite ends of a room: one shows fixed red tiles, the other lights up pink when you step on it.​

• Look at the panel with red tiles and memorize which squares are red.
• On the opposite, blank panel, step on tiles to light them up pink, but only on the tiles that are NOT red on the first grid.​
• In other words, invert the pattern: avoid all positions that were red and light up every other position instead.​

You must successfully complete this inversion three times (with different red patterns) to clear the puzzle and open the sealed room.​

Exhibition Hall Floor/Screen Puzzles (Related)

While not classic “floor tiles,” two Exhibition Hall puzzles often get grouped with floor puzzles:​

• Scoreboard corridor puzzle (Exhibition Hall east wing):
  • Solution: Turn on only the closest screen on the left and the furthest screen on the right to display Kiuchi’s best scoreboards and open the door.​
• TV “K” logo room (Exhibition Hall west wing):
  • Solution: Activate the central console only when every TV shows a “K” logo; do this three waves in a row to free the Golden Contract chest.​

Using these solutions, you can clear every major floor-based puzzle in Kiuchi’s Palace without trial-and-error and push your exploration toward 100%.
