Normal sudoku rules both do and do not apply!

The 12x12 grid is divided in to seven rooms by thick black lines, normal sudoku rules apply within each of these rooms, but do not apply across rooms (e.g: R1C6 and R1C7 could be the same digit). Each room also has its own puzzle to solve (described below).

Make sure you read the rules for room 7 before you start! You will need them throughout if you want to escape!

1. The Arrow Room

The digits along an arrow must sum to the digit in the bulb

-

2. The Red Room:

> adjacent digits that sum to 10 are connected by an X

> adjacent digits that are consecutive are connected by an empty white dot

> adjacent digits that are of ratio 1:2 are connected by an empty black dot

> all Xs and dots within the room are given (not necessarily with digits outside the room)

-

3. The Laser Room:

> Renban lines: digits along a red line are an unbroken consecutive sequence, but may appear in any order (the break in the line in cell R12C9 indicates these are two separate lines that share a cell)

> German whispers: neighboring digits along a green line have a difference of at least 5

-

4. The Tower Room

The three digits in the previous room marked by arrows (R10/11/12 C7) are simultaneously skyscraper clues and sandwich clues for their indicated rows.

> Skyscrapers: the number of cells visible from that end of the row, larger cells hide smaller cells behind them

> Sandwich clues: the total of the cells between the largest and smallest cell in the row (may or may not be between a 1 and a 9)

-

5. The X Room

The digits in the four cells around a corner black circle sum to the total in that cell. Digits cannot be repeated around the circle. Some of these black circles have spilled out and affect other rooms. The values of X, X+Y, and Z are to be determined by the solver. Y is the digit in the cell labelled "Y".

6. The Cages Room

Place in to each letter-shaped cage a tetromino such that…

> It does not overlap the cage lines (e.g: a 2x2 tetromino couldn’t fit in an E cage, but could fit in an A or P cage)

> It does not share an edge with a same shaped tetromino

> The total the twelve cells left outside the tetrominoes is the same as the total of the twenty-four cells inside the tetrominoes

> Each 7 in the room is a summing skyscraper: the tetromino digits it can see in all four directions, that are not hidden behind larger digits or “outies”, sum to 7

-

7. The Final Room

> Thermometers: Digits along a thermometer must increase from the bulb end, but don’t have to be consecutive

> The killer cage with the sum X is the six-digit code needed to escape the puzzle. They are the six digits throughout the puzzle indicated by the dotted squares, in some order.
