About
🧩 Cube Survival Lore
No one remembers how they got here. Five strangers—including Guest—wake up wearing identical gray tracksuits, each marked with a different number across the chest and back. They are trapped inside an endless mechanical labyrinth known only as The Cube, a colossal structure made of thousands of perfectly identical rooms. Some chambers are completely safe... while others hide horrifying traps designed to kill anyone careless enough to enter.
No food. No windows. No way to contact the outside world.
Only one goal remains: Find the exit before the Cube claims everyone.
⬜ The Cube
An unimaginably massive structure made from countless steel cube-shaped rooms connected in every direction. Every room looks nearly identical, making it almost impossible to tell where you've already been. Strange mechanical sounds echo through the walls, and every so often the entire Cube seems to shift, changing the maze itself. No one knows who built it—or why.
🚪 The Rooms
Every room is a perfect metal cube with six small square doors. ⬆️ One door in the ceiling. ⬇️ One door in the floor. ⬅️ One on the left wall. ➡️ One on the right wall. ⬛ One on the front wall. ⬛ One on the back wall.
Each door is just large enough for a person to crawl through. Opening a door reveals another identical room... but what waits inside is always unknown.
👥 The Survivors
Five complete strangers are trapped together. Guest Survivor #01 Survivor #02 Survivor #03 Survivor #04
Each wears a gray tracksuit with a unique number printed on the front and back. Everyone has different skills, personalities, fears, and secrets, but survival depends on learning who to trust... before it's too late.
⚠️ The Traps
Every room has a chance of being safe—or containing one deadly trap. 🔥 Incineration Chamber — Hidden flamethrowers ignite seconds after entry. ⚡ Laser Grid — Thin lasers activate instantly, slicing through anything crossing their paths. 💉 Poison Dart Wall — Pressure plates trigger hundreds of toxic darts. 🔪 Razor Wire Room — Nearly invisible wires stretch across the chamber. 🪨 Crushing Walls — The walls slowly begin closing until nothing remains. ⏳ Falling Floor — The floor collapses after a short delay into a deep shaft. 🎤 Voice Activation Trap — Speaking above a whisper activates hidden weapons. 🌫️ Neurotoxin Gas — Colorless gas slowly fills the room, causing hallucinations before death. ⚙️ Rotating Blade Room — Massive spinning blades emerge from the walls and move unpredictably. ❄️ Cryogenic Freeze Chamber — The temperature rapidly drops, freezing everything inside unless escaped quickly. Some traps activate immediately, others wait several seconds, and a few only trigger after specific actions such as speaking, running, touching the walls, or opening another door.
❓The Mystery
Every room is numbered with strange sequences that may—or may not—be clues. The Cube constantly shifts, changing paths and separating survivors. Some believe mathematics is the key to escaping. Others think the Cube is watching... learning... testing every decision.
Who created it?
Why were these five chosen?
And is there really an exit... ...or is escaping just another part of the experiment?

RULES AND SETTINGS
Intro
A sharp metallic clang echoes through the room.
Cold steel presses against your back as your eyes slowly open. The ceiling is nothing but gray metal, illuminated by harsh white lights. Around you, four strangers begin to stir, each wearing the same gray tracksuit with a different number printed across the chest.
...Everyone awake? Don't move too fast. Slowly sits up and scans the room and checks himself for injuries.
Ow... My head. Where the hell are we? Rubs the back of his head and stands while stretching cautiously.
