The locked safe in the Devil’s Reef hotel is one of the first real “figure it out yourself” moments in The Sinking City 2, and the puzzle is deliberately built to lead you to the wrong number. It sits in Room 301, it needs a four-digit combination, and the answer is hidden inside a set of song lyrics sitting several floors below.
Quick answer: Enter 2137 on the safe in Room 301 of the Devil’s Reef hotel.
What you need before you can reach the Devil’s Reef safe
The safe itself is behind a locked door, so the Staff Key comes first. Head to the third floor and enter Room 304, where a hotel employee’s corpse is holding it. The moment you try to grab the key, the body drops all the way down to the ground floor, taking the key with it.
Walk back down, pick the Staff Key up off the ground floor, and climb the stairs again. That same key also unlocks the rooms holding the Lorelei Tokens later, so it is worth grabbing early regardless of whether you care about the safe.
Note: the hotel has a decent number of enemies roaming it, and opening chests can trigger fresh spawns. Clear the floor you are on before you start reading notes.
Where to find the “Baby, One More Tide” lyrics
The combination is not written down anywhere as a number. It lives inside a piece of evidence called the “Baby, One More Tide” Lyrics, which you pick up on the ground floor in the VIP area, in the narrow room tucked behind the main bar counter.
The four lines that matter are these:
Spread my wings like a bat in flight / Curl my tail in hate and spite / Their octopus hearts beat in fear / As the tide makes all sins clear
There is a second note that confirms the lyrics are the key. Use the Staff Key on Room 303 on the third floor and you will find the Safe Code Letter, signed by Heloise, which points at the song directly and adds a postscript: “The beasts with eight have three, remember?” That line is the tiebreaker for the trickiest digit.
How each lyric turns into a digit
Each line contributes one number, in the order the lines appear. Read them as counts, not as shapes.
| Lyric | Digit | Why |
|---|---|---|
| Wings of a bat | 2 | A bat has two wings |
| Curl my tail | 1 | Singular — one tail |
| Octopus hearts | 3 | An octopus has three hearts, not eight |
| All sins | 7 | The seven deadly sins |
The two traps are obvious once you know them. “Curl my tail” tempts people into entering a number that looks curly, like 5 or 2, when the clue is simply that a tail is one. And the octopus line pulls your eye toward its eight legs, which is exactly what Heloise’s postscript is warning you about. The lyric says hearts, and an octopus has three of them.
Opening the safe in Room 301
What’s inside the Devil’s Reef hotel safe
The ammo is welcome this early, but the real reason to bother is the weapon mod. Voss’s Target Grip attaches to the full-auto rifle you pick up in the hotel and makes perfectly timed shots hit harder.
| Item | What it does |
|---|---|
| Voss’s Target Grip | Rifle modification; perfectly timed shots deal extra damage |
| Handgun Ammo | Standard sidearm ammunition |
| Shotgun Ammo | Shells for your shotgun |
Once the safe is empty, the Staff Key still has work to do in the hotel, and the Lorelei Lock down in the basement is the next thing standing between you and the rest of Devil’s Reef.
