An In-Depth Walkthrough for In Sink: A Co-Op Escape Prologue

Are you looking for a complete guide to escaping all 3 rooms in the popular indie co-op game In Sink? Then you‘ve come to the right place! Below I provide detailed solutions for every puzzle to help you and your partner achieve victory.

As a long-time gamer and escape room enthusiast, I‘ll be sharing my top tips and tricks throughout this walkthrough.

An Introduction to In Sink‘s Gameplay

In Sink is a unique multiplayer escape room game that relies entirely on collaboration between two players. Developed and published by FrozenShiver, it was released on Steam in September 2022 as a free prologue for their upcoming title Sink or Swim.

In the game, you and a partner control two characters trying to escape a strange island. According to Steam‘s description, you‘ll need to "brainstorm with your teammate to escape the rooms" by passing through portals to alternate worlds.

This means constant communication is key! You‘ll need to describe visual elements only you can see, relay number codes and patterns, and work together to unlock each door. It‘s an immersive, challenging test of teamwork.

As of January 2023, co-op and party games are one of the most popular genres on Steam. In Sink sits at Overwhelmingly Positive reviews, with 92% of 2,345 ratings recommending the free prologue. This shows there‘s excitement around the unique co-op premise.

Now let‘s get into the walkthrough so you and your partner can master In Sink‘s team-based puzzles!

Detailed Walkthrough for Each Room

There are 3 rooms total in the In Sink prologue, each with several puzzles to solve. I‘ll provide step-by-step instructions to breeze through every one.

Room 1 Walkthrough – Tutorial Tests Communication Skills

Room 1 serves as a tutorial, introducing the co-op mechanics through some beginner puzzles. Here are detailed solutions:

Puzzle 1: Communicate Matching Cube Codes

The first test is simple – both players have to describe the 3 numbers shown on their cube to their partner, who then inputs the code into their keypad.

Boy describes their cube numbers to Girl
Girl inputs Boy‘s code into her keypad: 334
Girl describes her cube numbers to Boy
Boy inputs Girl‘s code: 215

This gets you comfortable with the verbal coordination required in In Sink. Don‘t overthink it! Just clearly describe your cube‘s numbers to progress.

Puzzle 2: Match Colors on the Door Frame

For the second puzzle, look up at the colors bordering the top of your door frame. Going from left to right, list out the sequence you see to your partner.

Here‘s an example:

Boy: Blue, black, white, purple
Girl: Turquoise, yellow, orange, pink

The key is that you describe YOUR door frame colors. Don‘t just repeat what your partner said! Matching the colors unlocks the next part of the room.

Puzzle 3: Bottle Levers with Backstage Access

This puzzle has you manipulating levers based on clues from colored bottles. Here are the steps:

Girl stands on the stage so Boy can crawl through and access the backstage area.
Boy checks the bottle colors against the plates on the back wall.
The number of bottles corresponds to the lever number.
The plate color matches the bottle color – flip plates to see if a lever should be up or down.
Following the clues, Boy pushes levers 1, 6, and 8 up and all others down.

It seems complicated but simply match the colors and leverage counts to know which levers to adjust. This unlocks the next puzzle.

Puzzle 4: Filling Colored Cups with Symbols

The final Room 1 puzzle has you filling colored cups according to your partner‘s instructions:

Boy describes the cup color and number of ice cubes to Girl.
Girl finds the matching recipe and selects it.
When ready, Girl hits play to fill the cup with the recipe‘s symbol.
Some cups require being filled twice to fully solve them.
Once finished, Girl moves the cup to the right.
Repeat this 4 times until all cups are solved!

With good communication, you‘ll match all the cups and unlock the Room 1 exit. Nice work! Let‘s keep escaping.

Room 2 Walkthrough – Build On Teamwork Skills

Moving into Room 2, the puzzles get slightly harder. But don‘t worry – with collaboration, you‘ve got this!

Puzzle 1: Match Objects to Lever Positions

For the first puzzle, you need to match objects in the room to numbered lever positions. For example:

The apple is in position 1 on the table, so move the red lever left to position 1.
The pot is in position 2, so the blue lever goes in the middle at position 2.
The book on position 3 means the yellow lever should be moved right to position 3.

Get the idea? Relay the object positions to match the corresponding lever order. This will unlock the next challenge.

Puzzle 2: Chess Board Code

This puzzle requires both players‘ input to decipher a 4-digit code:

Girl stands on the weight in the floor so Boy can access the chess board.
Boy collects the number-letter combos scattered around the chess board.
By combining your respective clues, the code "2679" can be deduced.
Boy inputs 2679 on the keypad to unlock the exit!

Leveraging both players‘ information is key to cracking the code. Great teamwork!

Opportunity Achievement: Jump in the Sink

Before leaving, don‘t miss the chance to earn the "Opportunity to be more than just thinking alike" achievement!

Simply walk over to the kitchen sink and use the action button to jump inside. This unlocks a fun bonus for reaching the next room. Well worth taking a dive!

Room 3 Walkthrough – Final Puzzles Ramp Up The Challenge

This is it – the final room between you and escaping the island! Stay focused and work together to overcome these last puzzles:

Puzzle 1: Match Symbols Between Ship and Mannequins

For this puzzle, players have to combine visual clues:

Boy looks out the window at the symbols visible on the ship mast.
Girl examines the mannequins in the room to find the one with matching symbols.
Once identified, Girl uses that mannequin‘s color sequence on her model.
Repeat this symbol matching 3 times to unlock the next part of the room.

Though intricate, simply communicate carefully between players and you‘ll match the patterns.

Puzzle 2: Calculate Spinning Wheel Code

Next up is a mathematical challenge:

Boy fills in the missing numbers on his spinning wheel chart.
To decode the 4-digit password, Girl calculates x+y-z down each column.
For example, 4 + 7 – 3 = 8 in the first column.
Doing this for all columns gives the code 4458 to open the door.

Make sure to fill the entire chart so you can calculate the full code. Get your math skills ready!

Puzzle 3: Match Symbols to Escape Ship

Almost there! This second-to-last puzzle is mercifully straightforward:

Girl identifies which of the 4 rotating symbols is correct and describes it to Boy.
Boy then selects the corresponding symbol on his display, activating it.
Repeating this 6 times unlocks the door to escape the ship.

With clear communication, you‘ll be off the boat in no time. Just a few more puzzles between you and victory!

Puzzle 4: Navigate Obstacles to Reach the Exit

For the final puzzle, players have to avoid moving obstacles to reach the exit:

Boy can move up and down to avoid electricity barriers.
Girl can move left and right to avoid sweeping lasers.
By describing your respective obstacles and movements, navigate the maze to reach the exit (X).

It‘s a thrill to finish with this fast-paced, timing-based challenge. Follow my tips and you‘ll escape in no time!
