How to make a Minecraft Floor Is Lava server

A Minecraft Floor Is Lava server floods the world from the bottom up, one block at a time, and the last player left out of it wins. On JetRift you make one by choosing The Floor Is Lava, naming it, and sending your friends the address. It takes about ninety seconds, with nothing to install, because the lava is poured by the server. It runs Minecraft 26.2 on Java Edition.

How a round goes

You start with nothing on an ordinary map. The lava begins at the bottom of the world and rises a block every twenty seconds, and whatever you can tear out of the ground before it arrives is what you get to build with.

Only air is filled, so what you build to stand on stays standing. The lava drowns the world rather than dissolving it.

Starting a round

Create a Floor Is Lava world and send your friends the address.
Stand where you want the arena centred and run /floorislava start.
Dig, gather, and build upwards. The action bar tells you how close the lava is.
Last one dry wins.

Why it finishes quickly

Twenty minutes, start to finish. There is no equipment to prepare and no progression to keep track of, which makes it the mode to pick when somebody has half an hour rather than a weekend.

It is also deliberately bounded. The lava spreads sixty-four blocks from where the round started rather than across the whole world, so a round is a place rather than an errand.

What it costs

Nothing while JetRift is in early access. No credit card, three worlds per account, and a hundred and fifty hours a month across all of them. The world sleeps when nobody is on it and wakes up when somebody joins.

Make one now. Free, no card, and about ninety seconds from here to an address you can send your friends.

Common questions

Does the lava destroy what I build?

No. Only empty space is filled, so anything you place stays where you put it. The trick is having placed enough of it.

How big is the arena?

Sixty-four blocks out from where the round was started, which is about a two minute walk across. It can be set from the panel.

How fast does it rise?

A block every twenty seconds by default, so about three blocks a minute. That is also adjustable.

Can we play more than one round?

Yes, though the world will be full of lava afterwards. Restoring a backup from the panel gives you a clean map to play again on.
