[h1]20 IN. 1 OUT.[/h1]
A giant cube, assembled at random from 36 killing rooms. Twenty players drop in. Every door is a blind box — behind it might be a piston floor, a lava crucible, or a bowling alley with balls the size of cars. The traps kill. The cover moves on its own. And the outer ring keeps breaking apart and falling into the void.

Last one standing wins.

36 ROOMS, GENERATED FROM A SEED

No two matches are alike. Every match builds a new cube out of the room library, so whatever you learned about the map last round is gone. Rooms are graded into four danger tiers — safe, chaos, damage, lethal — and the tier is marked on the door. Read it and route around the killers. Or don't, and find out the hard way.

15+ hand-designed mechanism rooms are in the library right now, including:

• Piston Floor — pillars rise and fall; your cover moves on its own
  
• Flame Waves — travelling jets, timed to catch you mid-sprint
  
• Bullet Train — high-speed trains cut straight across the tracks
  
• Crushing Press — plates slam down; the gaps between them are the only life
  
• Tesla Cage — the coil discharges, and inside the cage is death
  
• Lava Crucible — magma kills on contact; the moving ferries are the only way across
  
• Frozen Sea — floes crack three seconds after you step on them, and the water kills
  
• Endgame Board — entire colours of the board vanish, and the drop kills
  
• Neon Bowling — giant balls roll the lanes and scatter everything standing

ONE SNIPER RIFLE. THE WHOLE MAP KNOWS.

There is exactly one sniper rifle per match, and it one-shots anyone it hits.

It also halves your movement speed, its report is heard across the entire map, and the moment you pick it up your position is broadcast to every player still alive. A gift and a curse in the same object. Twenty people will come looking for the rifle — and then for you.

NO CIRCLE. THE ROOMS THEMSELVES FALL.

There is no shrinking-circle timer here. Whole outer rooms crack, tip over and drop into the void:

36 → 24 → 16 → 10 → 6 → 3 → 1

Standing on one when it goes? You go down with it. The cube keeps closing until a single room is left and the fight has nowhere else to run.

TWELVE ZODIAC FIGHTERS

Tiger, fox, panda, horse, rabbit, leopard and more — twelve animal-headed fighters, nine weapons and ten trap families, all colliding inside the same collapsing box.

BRING FRIENDS, OR A WHOLE ROOM OF THEM

• Invite Steam friends straight from the lobby
  
• LAN party ready — auto-discovery or direct IP, built for people sitting in the same room
  
• 4 players to start a match; BOTs fill the remaining slots up to 20
  
• Solo practice against 19 BOTs whenever you want

BUILT IN THE OPEN

Enter the Cube is made by a one-person studio in Godot. The room library is the game, and it grows with the build. If a room isn't fun with twenty people inside it, we would rather hear that early and rebuild it — come tell us on Discord.
