Cracked Floor Arena

Start on a blue 21×21 floor where the tiles under your feet turn amber before dropping into the void. Keep moving as each pair of rounds makes the arena smaller and the warning becomes shorter. By round ten, only a 13×13 floor remains and amber tiles fall after half a second. Falling or stepping outside the floor sends you to the lobby until the next round.

Alone, try to survive every clock and beat your saved total survival time. With friends, the last player standing earns the round; equal scores at the end stay a draw. Ten lobby lamps track the match, and the floor rebuilds between rounds. Players who join after the start watch until the next match. Save and reload preserves the match with a short countdown before play resumes.

Open the .mcworld file and let Minecraft import Cracked Floor Arena, then choose it from Play > Worlds. No experiments or pack setup are needed. Needs Minecraft Bedrock 1.26.45 or later.
Gather 1–4 players in the lobby. Use the Lodestone, or hold crouch beside it for 1.5 seconds, to build round 1 and move everyone to separate arena corners.
Move off amber tiles before they fall. Stay inside the current floor; falling or leaving its edge returns you to the lobby for the rest of the round.
Survive the clock alone or be the last player standing with friends. After ten rounds, read the result and use the Lodestone for a rematch. The control stays locked during a match.
