Endless Stairwell is an Idle Game made by Demonin in September 2021, which as it states is loosely inspired by Reinhardt's House
The game is set in a huge building containing a seemingly endless stairwell. Some of the floors have doors leading to rooms. Most of the doors lead to regular floors, which have an infinite number of rooms; some of them contain a monster. The higher floor you are on and the further you get from, the more HP each monster has.
It is currently (As of April 2023) the incremental game with the largest numbers (You can reach numbers higher than Graham's Number). The developer hasn't added more content to the game (and larger numbers) because the game reached the limit of Expantanum, and as of the time of the game's creation, there are no libraries that support larger numbers, even to this day (as of April 2023).

Endless Stairwell contains examples of:
- Broken Bridge: On some floors, there are points where you cannot continue to higher floors until you collect a certain ring.
- Character Level: The levels determine how much XP and HP the player character has.
- Creepy Basement: Floor -1 is this as it is described as an enormous dark and dimly lit room with a "large, unknown machine" that is used to get dark orbs.
- Death Is a Slap on the Wrist: The only penalty for dying is that you lose a fraction of your XP, and even that penalty quickly becomes negligible after you get past the initial grind. This means waiting until the enemy kills you is often faster than going back to the stairwell.
- Early Game Hell: At the beginning of the game (before level 20-40), you will likely die a few times if you're not very careful, as you are quite weak with little HP and damage. This is in addition to the fact that early levels tend to give little bonus to your HP and attack damage. This is not the case after a New Game Plus, except if the player prestiges too early to get a significant bonus. This is in addition to the fact that you unlock a Flee button to avoid death when it is inevitable before you reach the next point where you can plausibly die.
- Escape Battle Technique: At a certain point in a game, the player unlocks the option to flee a room that has a monster (but it has a 4-second cooldown), which is useful for monsters the player has no chance of defeating.
- Experience Booster: The red runes increase your XP gain (5% per level for the permanent kind and 75% (in addition to the damage boost) for the temporary kind.
- Final Boss: On floor 499, there's a big golden eel that has Ke+15 HP, and it serves as this for the game.
- Gold-Colored Superiority: In the 8th and final tier, the enemies (including the Final Boss) are golden, and they drop golden honey that increases your attack power.
- Hyperactive Metabolism: Consuming honey or vanilla honey will replenish your health or energy, respectively.
- New Game Plus: There are a couple of forms of this, including:
- First, on floor 99, you can reset for cocoa honey, with the amount based on what level you reached. Cocoa honey multiplies your XP, and the bonus increases exponentially with how much XP you have. Then the player can reset their cocoa honey and everything that resets on a cocoa honey prestige for a cocoa bar if they have the cocoa honey requirement.
- Then, when the player reaches 10 cocoa bars, it unlocks access to floor -1 (the basement), which gives you the ability to do another layer of reset which is an even stronger type of reset, resetting everything unlocked up to this point (including cocoa honey and cocoa bars) in exchange for a dark orb which gives significant bonuses (such as an XP boost and a multiplier to honey gained) and possibly unlocks access to new content.
- Placid Plane of Ankle-Deep Water: A few of the floors are described as this.
- Quad Damage: The temporary Attack rune gives you +75% attack damage in addition to the aforementioned XP boost.
- Random Drops: The enemies often drop items that have varying effects. The items they can drop vary by floor.
- Sprint Meter: There is an Energy Meter that depletes when you attack. Also, when the energy meter is empty, you cannot attack; it stays empty for a few seconds before regenerating.
- Warp Whistle: You can unlock buttons to teleport to select floors for 100 cocoa honey (which is not given an in-universe justification, and they are simply called buttons). At first, you unlock the buttons to teleport to the ground floor, and floors 49 and 99 are unlocked, but more floors are unlocked later.
