Your trail follows behind
The ground behind you turns dangerous
As soon as you step on a solid block, the countdown begins: after two seconds it turns into magma. Two seconds later, it becomes lava. This only happens while the run is active.
Even when you jump, solid ground one or two blocks below you can turn into lava. Water, other fluids and waterlogged blocks stay unchanged. Moving on does not stop the blocks behind you from changing.
The trail advances only while the run is active. Water, other fluids and waterlogged blocks stay unchanged.
Example round: you cross a cave and see magma forming behind you. You look for the next safe ledge instead of turning back, because the old floor will soon become lava.

What to expect from your run
- Rule complexity
- The rule is easy to learn: keep moving and watch the ground behind you.
- Experience
- Good timing, careful jumps and awareness of your surroundings help.
- Time commitment
- The old route disappears as lava forms behind you, so you often need detours.
Before you stop
Tips for Floor is Lava
Keep moving and look for the next place where you can stand safely.
- 01Look for exits early
- Check caves, bridges and small platforms for your next place to stand.
- 02Use water as a route
- Water and waterlogged blocks do not become magma or lava and can offer a safer path.
- 03Plan around jumps
- Jumping can still make the ground below you start changing. Do not count on your way back staying safe.
