The four games behind this search
1. One Halloween Night
A realistic home-invasion horror game in Unity. You're a teen left home alone on Halloween, handing out candy to increasingly wrong trick-or-treaters. VHS camera effect, 3D sound, two endings decided by one late choice: hide or run. Not on Steam and not playable in a browser - the ~670 MB Windows download on itch.io is the only real version. Turn the volume up and wear headphones; the audio is intentionally quiet.
Download free on itch.io →2. Universal's Halloween Horror Nights event game
The official Halloween Horror Nights mobile game lives inside the Universal Orlando and Universal Studios Hollywood apps. It mixes trivia about that year's haunted houses with AR mini-games and achievements you unlock around the park. It is built for guests at the event - it only runs on select event nights and is not a standalone download.
Universal Orlando resort →3. Halloween Horror Nights on Roblox
A fan-made recreation of the Universal event on Roblox: walk-through horror mazes based on Halloween, The Purge and Asylum in Wonderland, plus scare zones on the streets between them. Runs on event-style night schedules. It is an unofficial tribute - expect jank, but it scratches the maze itch without a plane ticket.
Search "Halloween Horror Nights" on Roblox →4. Halloween Online Horror Night
An upcoming multiplayer horror game by RedFireFish: a plague doctor hunts a lobby of players through dark locations while you solve puzzles and coordinate over voice chat to escape. Listed on Steam as "Coming soon" - you can wishlist it, but you cannot play it yet.
Wishlist on Steam →One Halloween Night - both endings, no spoilers past this line
The game is short and the split comes late. If you want both endings without two full runs, save this order.

1
Play the night through normally
Answer the phone, do the chores your mom leaves (candy wrappers, the backyard noise), keep answering the door. The game moves forward when each chore finishes.
-
2
Reach the 1:30 AM choice
Late in the night the game gives you one real decision: escape the house or hide.
-
3
Hide for the good ending
Hiding leads to the rescue ending. Choosing to escape gets you caught - replay the final choice to see both endings in one sitting.
Sites offering an "unblocked" or browser-playable One Halloween Night are not official - the only real build is the Windows download from the developer's itch.io page. Do not run executables from clone sites.
