Edmund McMillen once said that The Binding of Isaac is a game about his own religious upbringing and the trauma of feeling like a monster. If you've spent dozens of hours dodging tears and blood, you know that the binding of isaac endings aren't exactly "happy." They’re messy. They’re kind of gross. Honestly, they’re heartbreaking once you piece together what's happening in that small cardboard box.
Most players see the credits roll for the first time after beating Mom and think they’ve seen the game. They haven't. Not even close. There are twenty-two distinct endings now, especially after the Repentance DLC basically rewrote the emotional weight of the entire saga. It's a journey from a child's imagination into a suffocating reality.
The Early Endings: Escapism and Suffocation
The first time you beat Mom’s Heart, you get a quick cutscene. Isaac finds a chest. He climbs in. It feels like a victory, right? Wrong. That chest is a recurring motif that represents Isaac’s desire to hide from a world that hates him, but it also literally becomes his coffin.
As you unlock more of the binding of isaac endings, the tone shifts from "boy fights monsters" to "child deals with a broken home." Take Ending 10, for example. You beat ??? (Blue Baby) in the Chest. You see Isaac looking in a mirror, seeing himself as a demon. This is the core of the game's tragedy. Because his mother calls him sinful and "corrupt," Isaac believes he is the monster. He isn't actually fighting demons in a basement; he's fighting his own reflection in a house where he doesn't feel safe.
Then there’s the Delirium ending. It’s one of the most abstract and difficult to unlock. After you defeat the static, shifting mass of Delirium, you see a sequence of Isaac’s life flashing before his eyes. It’s chaotic. It’s fast. You see his father leaving. You see his mother’s descent into religious mania. And then, you see the drawings. Isaac’s drawings are his only escape. But in the end, he's still in that chest. The air is running out.
The Finality of Repentance: The Beast and "Home"
When Repentance dropped, it added the "True Ending." This is what most people are searching for when they talk about binding of isaac endings because it actually provides some semblance of a narrative bridge. To get here, you have to go through the "Home" path, which is honestly one of the most atmospheric sequences in any roguelike.

You aren't in a dungeon anymore. You're in Isaac’s house. The music is gone, replaced by the muffled sound of a television. You hear his parents arguing. It’s a toxic, loud, terrifying environment for a kid.
- The Mother fight: This represents the physical threat.
- The Dogma fight: This represents the poisonous religious media Isaac was forced to consume.
- The Beast fight: This is the ultimate confrontation with Isaac's fear of the Apocalypse.
After you defeat The Beast, the game does something it has never done before. It gives us a voiceover. This isn't just random narration; it's Isaac’s father (voiced by Matthias Bossi) telling him a story.
Is it real? Some fans, and even certain lore theorists like those on the Isaac subreddit, argue that this is Isaac’s dying hallucination. He’s imagining a version of his dad who stayed. A dad who tells him a bedtime story where he isn't the monster. Others think it’s a flashback to a better time before the divorce destroyed the family. Regardless, it’s a gut-punch.
Why the "Hush" Ending Matters More Than You Think
Hush is a weird boss. He's a blue, suffocating version of Isaac. When you beat him, Ending 17 plays. You see Isaac walking in a grassy field, but then the scene transitions back to the missing person posters on a telephone pole.
Isaac is gone.

The game doesn't hide this, but it layers it under so much symbolism that it’s easy to miss. The "Blue Baby" character is Isaac’s corpse. The "Lost" is Isaac’s soul. Every ending where he climbs into the chest is a step closer to his actual, physical death from suffocation. It's dark, but it’s why the game resonates. It's not about winning a video game; it's about a kid who couldn't find a way out of his own head.
What Most People Get Wrong About the Story
A lot of players think Mom is the "villain." She is, in a literal sense, but the binding of isaac endings suggest a more complex reality. The father is also a "villain" for leaving. He took the money. He had a gambling addiction. You see this in the items like "Dad's Key" or "Binky."
Isaac is caught in the crossfire of two broken adults.
The monsters he fights—Gurdy, Monstro, Mom’s Heart—are often distorted versions of things in his life. Gurdy is just a pile of entrails, reflecting the "grossness" Isaac feels about his own body. He thinks he’s "bad" because he’s a boy who likes to play dress-up (the transformations) and his mom told him that’s a sin.
The ending of Repentance is the only time Isaac gets to be just a kid. Even if it’s a hallucination as he passes away in that chest, he finally gets to hear the words: "Are you sure this is how you want the story to end, Isaac?"

How to Unlock the Major Endings Without Losing Your Mind
If you're trying to see all the binding of isaac endings, don't try to rush it. The game is designed to be played over hundreds of hours.
- Beat Mom’s Heart 11 times. This is the baseline. It unlocks the path to the Cathedral and Sheol.
- The Polaroid and The Negative. You have to beat Isaac (in the Cathedral) or Satan (in Sheol) five times each to get these items. They are the keys to the "final" floors.
- Mega Satan. You need to blow up Angel Statues or use Mr. Me! to get the key pieces. This ending is mostly just a giant "The End" sign, but it’s a rite of passage.
- The Strange Door. After beating Mother once, you can find a door in the Depths. This leads to the "Home" sequence. This is where the emotional payoff is.
It’s worth noting that the game’s creator, Edmund McMillen, has confirmed that Isaac’s fate is "sealed." There is no "hidden" ending where Isaac climbs out of the chest and everything is fine. The tragedy is the point.
Actionable Steps for Lore Hunters
If you want to truly understand the binding of isaac endings, stop skipping the cutscenes once you've unlocked a new one. Each one adds a tiny piece of the puzzle.
- Read the item descriptions: Items like "Guppy’s Tail" or "The Photographs" aren't just power-ups. They are pieces of Isaac's life. Guppy was his real cat. The photographs show his parents before they hated each other.
- Watch the "Ascent" dialogue: When you are going back up through the floors to reach the Home ending, listen to the voices. That is the actual story of the divorce playing out in reverse.
- Look at the floor names: The "Corpse" floor isn't just a spooky name. It’s a literal description of what Isaac is becoming as he stays in that chest too long.
The story of Isaac isn't a happy one, but it is a deeply human one. It’s about how we use stories to cope with things that are too big and too scary for us to handle. Whether Isaac is ascending to heaven or just drifting off into a final, peaceful dream, his story remains one of the most profound narratives in indie gaming history.
To see the final ending yourself, focus on completing the "Mother" route first, as it unlocks the "Strange Door" mechanic needed for the True Ending. Once you've reached the "Home" floor, sleep in Isaac's bed to trigger the final sequence. Pay close attention to the narration; it recontextualizes every single run you've ever done.
