How to Save and Load in Sinner Maker (and Not Lose Your 100-Day Run)

The short answer for how to save and load in Sinner Maker is that you can't—at least, not in the traditional way. The game deliberately omits a manual save feature, relying instead on a strict, single-point autosave that only triggers when you sleep in your bed to advance to the next day. Understanding this unforgiving system is the first true test of your survival.

Any progress made during a day—items scavenged, stats increased, followers gained—is temporary. If you quit the game, suffer a crash, or lose power before successfully sleeping, the entire day is wiped clean. You will reload at the beginning of that same day, as if none of it ever happened. This design is intentional, forcing every decision to carry weight and making each new dawn a hard-won victory.

01

Why You Can't Just "Save Game"tag

Sinner Maker’s design philosophy borrows heavily from punishing roguelites and survival horror games where consequence is king. The developers have created a system where your actions are largely permanent. There are no take-backs from a disastrous encounter or a poorly spent day. The tension of the 100-day countdown is amplified by the knowledge that your only safety net is making it back to your hideout alive.

The game's one and only save trigger is the act of ending the current day. When your Apostle interacts with their bed and you confirm you want to proceed to the next morning, the game writes your progress to the disk. This is the point of no return. Once "Day 43" appears on screen, everything you did on "Day 42" is locked in, for better or for worse. This system forces a strategic rhythm: venture out, complete your objectives, and retreat to the relative safety of your hideout to bank your progress before risking it all.

The Only Safe Way to Quit Your Gametag

To avoid the heartbreak of losing hours of progress, you must adopt a strict end-of-session ritual. Simply closing the application from a city street or during a mission is a guaranteed way to lose that day's work. Follow these steps precisely every time you intend to stop playing.

Step 1: Complete All Essential Daily Actionstag

Before you even think about quitting, make sure you've done everything you need to for the day. Have you spent your action points? Scavenged the necessary materials? Interacted with key followers? Once you go to sleep, you can't go back. Rushing to save can be as dangerous as forgetting to save at all.

Step 2: Return to Your Hideouttag

Your hideout is the only location where you can progress time and trigger a save. No matter where you are in the sprawling, decaying city, your final objective for any play session is to make it back to this central hub. This journey back can be fraught with danger, adding another layer of strategic planning to your daily routine.

Step 3: Interact with the Bed and Confirmtag

Inside the hideout, the bed is the key object. Interacting with it will bring up a prompt asking if you're ready to end the day and proceed to the next. This is your final chance to double-check if you've forgotten anything. Once you confirm, the screen will fade to black as the day concludes.

Step 4: Wait for the New Day to Loadtag

This is the most critical step. Do not close the game when the screen is black. Wait until the game fully loads and the new day's number (e.g., "Day 43") appears on your screen, along with your Apostle's updated status. Once you see this, your progress from the previous day is officially secured. At this point, you can safely quit to the main menu or close the application entirely. Your next session will begin at the start of this new day.

For the Desperate: How to Manually Back Up Your Save Filetag

This method is not endorsed by the developers and circumvents the game's intended design. It's often called "save scumming." However, if you're facing a game-breaking bug or want a safety net against a devastating loss, manually backing up your save file is the only way. Proceed at your own risk, as improper handling can lead to save file corruption.

First, you need to locate the save file on your computer. For most Windows users, the path will be:

C:\Users\[YourUsername]\AppData\Roaming\SinnerMaker\saves

To easily find this, you can type %APPDATA%\SinnerMaker\saves into the Windows search bar or a File Explorer address bar and press Enter. Inside this folder, you will find files corresponding to your save slots, often named something like save_slot_1.dat.

To create a backup:

1. Copy the entire saves folder. Do not just copy the individual files inside.
2. Paste the copied folder to a safe location, like your Desktop or a dedicated backup folder. It's wise to rename it with the date and in-game day (e.g., SinnerMaker_Backup_Day_65).

To restore a backup:

1. Delete the current saves folder located in the %APPDATA%\SinnerMaker directory.
2. Copy your backup folder (e.g., SinnerMaker_Backup_Day_65).
3. Paste it into the %APPDATA%\SinnerMaker directory.
4. Rename it back to simply saves.

When you next launch the game, it will load the state from your backup. This can be used to retry a day that went horribly wrong, but it fundamentally breaks the ironman-style challenge the game is built around.

Common Save-Related Bugs and Pitfallstag

While the save system is intentionally harsh, players have reported a few issues that go beyond design. Being aware of them can save you a headache.

• Cloud Save Conflicts: If you play on a platform like Steam, be wary of cloud sync errors. If you play on two different computers, ensure the cloud has fully synced before launching the game. A mismatch can sometimes cause the cloud to overwrite your newer local save with an older version, rolling back your progress.
• The "Stuck Day" Glitch: In rare cases, the game can fail to properly save after you sleep, reloading you at the start of the same day you just finished. This is often caused by a background process interfering with the game's ability to write to the disk. If this happens, try restarting your computer before playing again. Manually backing up your save is your best defense against this.
• Alt+F4 is Your Enemy: It bears repeating. Force-quitting the game is the most common way players accidentally lose progress. The game does not save when you pick up an item or complete a mission; it only saves when the day ticks over. Treat Alt+F4 as a last resort for a frozen application, and accept that any progress from the current day will be lost.

Frequently Asked Questions (FAQ)tag

Can you have multiple save slots in Sinner Maker?tag

Yes, the game typically provides three separate save slots. Each slot operates independently with its own 100-day cycle and follows the same strict autosave rules. You can use these to experiment with different character builds or choices without overwriting your main run.

Does Sinner Maker have permadeath?tag

Not in the traditional sense of deleting your save file upon death. If your Apostle dies or you otherwise fail the 100-day challenge, that run is over and you must start a new game from Day 1. However, the save slot itself is not deleted, allowing you to try again.

Will the developers add a manual save feature?tag

It is highly unlikely. The entire gameplay loop, risk/reward structure, and oppressive atmosphere are built upon the foundation of the current autosave system. Adding a manual save option would fundamentally change the game into a much more forgiving, and arguably less impactful, experience.

How do I know for sure the game has saved?tag

The only 100% reliable confirmation is seeing the screen for the next day appear after you sleep. For example, if you finish Day 25, you are only safe once you see "Day 26" and your character status displayed. That is the moment the save file has been successfully updated.

Your Choices Are Meant to Mattertag

The save system in Sinner Maker isn't a bug or an oversight; it's a core mechanic. It's a declaration that actions have consequences and that survival is earned, not given. By forcing you to commit to the outcome of each day, the game elevates the stakes of its grim world. Mastering this daily cycle of risk and reward is the first, and perhaps most important, skill you must learn to guide your Apostle through their 100-day trial.
