How do I figure out the number on the red chart?

The chart shows several completed rows of numbers that follow a consistent arithmetic rule. Work out the relationship between the values in each completed row, then apply the same rule to the row with the missing entry to calculate the answer.

What is the hexagonal blue button for?

It activates the seven-segment LED panel on one of the appliances. Once you place the button, the display lights up and shows a code you need to progress.

Are there items inside the washing machines?

Yes — tap the colored doors on the front-loading washers. At least one drum contains a hidden item needed to complete the level.

Rooms & Exits Level 31 Walkthrough

hard

A sprawling appliance showroom with red and blue walls, stacked ovens, four color-coded refrigerators, and a row of washing machines — crack a number-chart arithmetic pattern to unlock the dark gray fridge's keypad, decode a seven-segment LED display, and hunt through oven cavities and washer drums for hidden items to escape.

Board Notes

Layout: Left wall: metal shelving holds rows of white stoves and ovens with rotary knobs. Center-back: four large refrigerators standing side by side — blue double-door, pink single-door, dark gray with an integrated number keypad, and white bottom-freezer. Right wall: front-loading washing machines with yellow, purple, green, and blue doors below a 'HOME APPLIANCES' poster. A central checkout island sports a cash register, a scale, and a wall clock. A puddle of spilled liquid stains the floor in front of the island. Near the entrance, a display stand shows colored irons and a knife block.
Goal: Derive the missing value from the red number chart, enter the code on the dark gray refrigerator, decode the seven-segment LED display, collect all hidden items from appliances, and escape the showroom.

Quick Tips for Rooms & Exits Level 31 (spoiler-free)

Study the completed rows on the red number chart first — find the arithmetic rule before guessing the keypad code.
Check every oven cavity and washing machine drum; items can hide in appliances you would not normally open in a store.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Rooms & Exits Level 31 — Full Solution

Search the oven compartments on the left wall — open doors and pull out lower drawers to find hidden items. Check behind the stove knobs and on the shelving.
Examine the four refrigerators: open each door and look inside. Find the red number chart on one fridge and study the rows to deduce the arithmetic pattern, then calculate the missing value for the incomplete row.
Enter the derived code on the dark gray refrigerator's keypad to unlock it and retrieve the item stored inside.
Locate the hexagonal blue button and use it on the appliance panel to activate the seven-segment LED display. Read the colored digit segments carefully to get the secondary code, then apply it to escape.

Common Mistakes to Avoid

Misreading the seven-segment LED display because its colored segments blend into the panel — each color represents a distinct digit boundary.
Overlooking the washing machine drums on the right wall; they look decorative but at least one hides a required item behind its colored door.
