Two modes, chosen in the lobby

The host picks Creative or Survival before the world starts. The default is Creative. In Creative the hotbar is nine slots of the solid blocks, 64 of each: grass, dirt, stone, cobble, wood, planks, sand, and leaves. Placing does not spend them. Breaking does not give you anything, because you already have the set. You choose the block and put it against an existing face. You cannot place into another player, and you cannot place a block with no neighbor to attach to.

Survival-lite is the other switch, and it is lighter than the name sounds. You start with an empty hotbar. Breaking a block puts a drop in your inventory, up to 64 in a stack. Grass breaks into dirt. Stone breaks into cobble. Leaves break into nothing. Everything else drops itself. Placing spends one from the selected slot. There is no health bar, no hunger, no day clock, and no hostile mob in this build. “Survival” here means the blocks you place had to be mined, not that the world is trying to kill you.

Walking, reach, and a world that grows

You look and move from your device. Break and place reach a few blocks out. The server rejects a click that is too far, so a wild tap at the horizon does nothing. The world begins at 48 by 32 by 48 blocks. Walk toward an edge and it can expand, up to a soft cap of 192 by 48 by 192, shifting the origin if you travel the negative direction so the coordinates stay in range. Everyone receives the new chunks. A friend who joins late gets a full snapshot, not a blank meadow.

Player colors are dealt from a short list, red, blue, green, and orange, so you can see who is standing on your roof. Nicknames float with them. Leave the room and your avatar is removed. Come back and you are added again, up to four. There is no score and no finish line. The session ends when the group closes it.

TV, phone, or both

Create the world from Main screen if you want a shared window on the wall, then have people join and choose the mode that puts the world and the controls on their own device. Or skip the TV and create it from the player home. Both are supported. A living-room build with the TV up is nice for a child who wants an audience. A remote build with four phones is the more natural way to play, because each person needs their own camera.

The terrain is procedural from a seed stored with the room. You are not loading a saved realm from a launcher, and you are not signing into an account. When the room is gone, the world is gone. Build things you are happy to lose, or accept that this is an afternoon, not a server you return to next month.

Things that save a build session

Use QuickCraft when the board games have worn the room out and someone still wants to do something with their hands. Use a race or a drawing game when you need a winner.

• Agree on Creative or Survival before anyone places a block. Switching is a lobby choice, not a mid-world menu.
• In Survival, mine stone if you want cobble and mine grass if you want dirt. Leaves are decoration you cannot pick back up.
• Do not build the floor someone is standing on out from under them without saying so. The game will refuse a block inside a player, and it will not referee griefing that stays outside their hitbox.
• If the TV is only a mirror, mute the expectation that it is the “real” view. Each player’s camera is their own.
• Four is the cap. A fifth person watches or waits for a seat.

FAQ

What is the difference between Creative and Survival?

Creative gives you 64 of every solid block and placing is free. Survival-lite starts empty: you mine what you place. Grass drops dirt, stone drops cobble, leaves drop nothing. There is no health, hunger, or mobs.

How big is the world?

It starts at 48×32×48 blocks and can grow as you walk, up to 192×48×192. Late joiners receive a full copy of the blocks.

How many people can build?

One to four. You can start from a phone or from the Main screen. Each builder looks around on their own device.

Does the world save?

It lives with the room. There is no account and no persistent realm in this version. When the room ends, the build ends with it.

Can I place blocks anywhere?

A block has to sit against an existing block, inside the world, in reach, and not inside a player. The server rejects the rest.
