Last puzzle (top of tower)

Hint #1

The positions of the walls, starts, and exits have a hidden meaning.

Hint #2

This puzzle uses a gimmick that is also used in other puzzles in the Keep.

Mountain Floor

Hint #1

If the polyominoes are split down the middle, the total number of polyomino blocks must be an even number. If they are all combined in the center, the total number of polyomino blocks must be an odd number.

Hint #2

Some puzzles may have only one valid shape that can be made. Do these first, then figure out what to do with the others.

Multi-eraser Puzzle

Hint #1

An eraser won't erase a symbol if it is not wrong (blinking red).

Hint #2

Stars are considered correct if they are paired with a symbol of the same color. This includes erasers.

Negative Poly Puzzles

Hint #1

It can be easier to visualize solutions if you imagine erasing squares from the polyominoes before fitting them together. However, this won't always result in a valid solution, as it may cause polyominoes to extend past the edges of the grid. See the "Known Issues" wiki page for more information about this.

Hint #2

One strategy is to focus on covering all the symbols first, then remove blocks to deal with any overlap.

Last puzzle before the laser:

Hint #1

In the original game, this puzzle changes the symmetry unexpectedly. The same thing happens in this version.

Hint #2

Look at the change in position of the exit between the two puzzles. Think about what type of rotation/reflection would produce that kind of change.

Dot puzzles

Hint #1

The second puzzle teaches you that both lines may follow the same sound cue.

Hint #2

Remember that some sound cues may be red herrings.

Dot puzzle sound cues

Puzzle #1 & #2: HIGH, LOW

Puzzle #3: MID, MID, HIGH, MID, LOW

Puzzle #4 (two cues): LOW, MID, MID, HIGH, LOW / HIGH, MID, HIGH, LOW

Purple Pressure Plates

Hint #1

The intended solution passes through the obstructed area near the top of the puzzle.

Hint #2

Take a walk around the area surrounding the pressure plates. There may be some important details that you didn't notice before.

Hint #3

You'll have to solve the other pressure plate puzzles before you can solve this one.

Green Pressure Plates

Hint #1

The intended solution doesn't use the edge at the entrance of the puzzle.

Hint #2

For this puzzle, the panel is visible from inside the maze. This fact is important.

Blue Pressure Plates

Hint #1

The intended solution uses the upper-right start point.

Hint #2

When you walk the solution, you will end at the start.

Last puzzle (top of tower)

Hint #1

The positions of the walls, starts, and exits have a hidden meaning.

Hint #2

This puzzle uses a gimmick that is also used in other puzzles in the Keep.

Mountain Seal (Perspective)

Hint #1

The correct perspective for one of the locks may require going between a statue's legs.

Dual Bridge Puzzle

Hint #1

Try getting the dot with the orange line instead of the cyan.

Mountain Floor

Hint #1

If the polyominoes are split down the middle, the total number of polyomino blocks must be an even number. If they are all combined in the center, the total number of polyomino blocks must be an odd number.

Hint #2

Some puzzles may have only one valid shape that can be made. Do these first, then figure out what to do with the others.

Stars puzzle to unlock the ramp

Hint #1

Remember, stars are considered correct if they are paired with a symbol of the same color. This includes erasers.

Hint #2

For an eraser to erase a star of its own color, you must put other symbols of that color in the same group.

Negative Poly Puzzles

Hint #1

It can be easier to visualize solutions if you imagine erasing squares from the polyominoes before fitting them together. However, this won't always result in a valid solution, as it may cause polyominoes to extend past the edges of the grid. See the "Known Issues" wiki page for more information about this.

Hint #2

One strategy is to focus on covering all the symbols first, then remove blocks to deal with any overlap.

Central Starting Point Puzzles

Hint #1

When a central starting point is used, either all of the surrounding points are covered by polyominoes, or none of them are.

Glass factory symmetry, last dots puzzle

Hint #1

If a solution isn't accepted, a condition on the puzzle isn't being met.

Hint #2

The two brackets on the bottom of the panel are important.

Glass factory symmetry, last multi-exit maze puzzle

Hint #1

Find the pair of exits which are symmetric to each other. Those are the exits you have to get to.

Hint #2

The solution is much simpler than you think.

Four-triangle puzzles

Hint #1

The two lines can pass through each other.

Hint #2

Try getting three edges of the triangle with your line and let the symmetry line pick up the last one.

Church Star Door

Hint #1

You must solve this puzzle without opening the yellow glass door.

Hint #2

A yellow filter removes blue light. Think about the RGB of each color and what would happen if the B was removed.

RGB Room

Hint #1

The red light cannot be activated.

Hint #2

An eraser can help you determine which symbols are the same color.

Getting to the laser

Hint #1

You still need to use the two orange bridges.

Hint #2

You'll need to pivot one of the bridges in two different directions.

Getting out of the tutorial area

Hint #1

The only way out is to deactivate the laser door.

Hint #2

The bottom exit on the two-exit puzzle is impossible to finish at.

Hint #3

Look at the panel controlling the laser door. It is different than before.

Tutorial Vault

Hint #1

You should solve the other puzzles in this area before attempting this puzzle.

Hint #2

Only one of the start points will allow you to pick up all the dots.

Shipwreck Vault

Hint #1

You should complete the symmetry and jungle areas before attempting this puzzle.

Hint #2

The two sound cues are LOW, HIGH, MID and MID, LOW, MID, HIGH. Try having your drawn line collect the orange dots and the symmetry line collect the pink.

Hint #3

Look at how many medium-sized dots there are. This will tell you which sound cue(s) need to be followed.

Hint #4

The fact that the two lines can overlap is essential to solving this puzzle.
