Big Walk Invisible Ink Puzzle Solution
Nine tiles look blank until you read them through the fixed red lens. Identify all nine symbols, read the five-symbol target for your current attempt, then place the matching tiles in order. The target can change, so a sequence from someone else's game may not work.

Looking for a nine-symbol puzzle you are not allowed to talk about? That is a post-game Purple Challenge, not Invisible Ink.
Quick Solution
- 1Hold each of the nine blank-looking tiles up to the fixed red lens and name its symbol.

- 3Read the five-symbol target for the attempt you are in now.
- 4Gather the five tiles that carry those symbols.

- 6If the check fails, read the target again before retrying — it can change.
Why Another Player's Answer May Not Work
- Always the same
- Nine tiles to reveal
- The fixed red lens
- Five target symbols

- The check at the end
- Changes
- Which five symbols are asked for
- The order they have to go in

Hints
Small hint
The tiles are not really blank. Find the one thing in the room that shows what is written on them.
Strong hint
One player reads the fixed red lens while a teammate holds each tile in its sightline. Identify all nine tiles before you commit to the current five-symbol target.
Step-by-step
- Step 1
Phase 1 — Reveal the hidden symbols
One player stays at the fixed red lens. A teammate picks up each blank-looking tile and holds it where the lens can see it.
- Find the nine blank-looking tiles.
- Put one player at the fixed red lens.
- Hold each tile in the lens's sightline and say out loud which symbol you see.
- Keep going until all nine tiles have a symbol.
Tip: The lens does not move. Bring each tile into its sightline instead of carrying the lens around the room.
- Step 2
Phase 2 — Remember which tile is which
Back on the table the tiles look identical again, so give each one an identity before you start placing anything.
- Lay the nine tiles out in a fixed grid, for example three rows of three.
- Number the tiles 1 to 9 and keep that order.
- Note the symbol that belongs to each number.
- Check that no two tiles were given the same number.
Success check: You can name a symbol and go straight to its tile without guessing.
- Step 3
Phase 3 — Match the target
The target shows five symbols for the attempt you are in. Find the five tiles that carry them.
- Read the current five-symbol target.
- Find the tile for each symbol.
- Bring those five tiles to the answer rail.
Success check: You can point at all five matching tiles.
- Step 4
Phase 4 — Place in order and validate
The answer rail has five positions, and the position of each tile matters.
- Place the first target symbol in position 1.
- Fill positions 2 to 5 in target order.
- Trigger the check.
- If it fails, read the target again before you retry.
Success check: Every position holds one tile, in the exact target order.
You solved it when
- ✓ All five positions are accepted
- ✓ The check succeeds and the puzzle does not reset
- ✓ The Gourd becomes available
Invisible Ink Helper
Map the nine tiles in front of you to the symbols you saw through the lens, then enter the target your game is showing. The helper tells you which physical tile to pick up for each position.
Number the symbols the same way in both lists — the labels are yours to choose, but the same shape has to get the same number every time.

How to Remember the 9 Invisible Ink Tiles
Recommended method
Do not try to remember roughly where a symbol was. Give every tile a stable identity before you activate the target.
- 1Lay the nine tiles out in a fixed grid, for example three rows of three.
- 2Number the tiles 1 to 9 and keep that order for the whole attempt.
- 3Say or note the symbol for each number as you reveal it through the lens.
- 4Reveal every tile before you touch the target, so no tile is left unnamed.
- 5Leave the grid in place while you place your answer.

Invisible Ink Not Working?
A copied answer does not work
Likely cause: That answer belongs to a different attempt.
Fix: Read the five-symbol target in your own game and rebuild the sequence from it.
The tiles all look blank
Likely cause: The symbols only appear through the red lens.
Fix: Hold each tile up to the fixed lens. Do not carry the lens away from its mount.
All five tiles fit, but the check still fails
Likely cause: Tiles that belong in this puzzle are not the same as the right tiles in the right order.
Check
- You identified all nine tiles correctly
- These are the five symbols the target asks for now
- The tiles sit in the exact target order
- The target has not changed since you last tried
- The check was actually triggered
Fix: Re-read the target, rebuild the order, then trigger the check again.
A tile will not go into a position
Likely cause: You are holding a tile that does not belong to this puzzle, or one that is already placed in another position.
Check
- The tile is one of the nine tiles from this room
- The tile is not already sitting in another position
Fix: Pick up one of the nine tiles from this puzzle instead.
The puzzle reset
Likely cause: The check failed, which clears the attempt.
Fix: Re-read the five-symbol target before you retry. Do not repeat the previous order.
The Gourd did not appear
Likely cause: Passing the check and collecting the reward are two separate moments.
Check
- The check succeeded
- The puzzle is not still showing a failed attempt
Fix: Confirm the success state, then collect the Gourd.

Why are the tiles blank?
The symbols only show up through the puzzle's fixed red lens. Hold a tile in the lens's sightline and its symbol becomes readable.
How many tiles are there?
Nine tiles to identify, a five-symbol target, and five answer positions. You reveal all nine symbols, but only five go on the rail.
How do I use the red lens?
One player looks through the lens while a teammate holds each tile in front of it. The lens stays where it is, so the tiles travel to it.
Why doesn't another guide's answer work?
The five-symbol target is built for your attempt and can change. A sequence copied from another game may be correct for that game and wrong for yours.
How many players does Invisible Ink need?
The reveal uses two active roles: one player reads the lens and one holds the tiles. Extra players can share the sorting and the memory work.
Is Invisible Ink a Green Tower or Blue Tower puzzle?
This site tracks it with Green progression. Some community guides label the room from the nearby Blue-side landmark, so both names appear in searches. Use the map marker if you are trying to find it.
Why did the puzzle reset?
A failed check clears the attempt, and the target can change afterwards. Re-read the five-symbol target instead of repeating your last order.
