SpleefWars
by knechterus
SpleefWars adds an automated Spleef minigame system to Fabric servers, with timed rounds, arena resets and elimination for multi-round matches.
What it does
Each match runs over several rounds, and only the top half of each group moves on after a round ends. The lobby group system sorts players into arenas. Snow blocks break under a player who stands on them for 3 seconds, and falling below the arena's lava line eliminates a player. The arena resets automatically after each round, so a server can run matches back to back once it has been configured.
The mod is built for server owners who want competitive Spleef tournaments. Commands are run once to configure an arena, after which the rounds, lobbies and resets operate without staff input. Spectators can be teleported into the match, and the power-up system adds speed, invisibility and snowballs. Snowballs break snow blocks, which lets players open holes in the floor of other players' arenas.
SpleefWars requires Fabric API. Files are published for Fabric only, for 1.21.11, and the environment is server-side only, so players join without installing anything. The mod is all rights reserved and is not open source.
Key features
Multi-round elimination
Only the top 50% of each group advance after a round, narrowing the field until a single winner remains.
Automatic arena reset
Each arena is restored after a round ends, so the next match starts on an intact floor without manual rebuilding.
Snow break timer
Snow blocks give way after a player stands on them for 3 seconds, and snowballs can break them sooner.
Power-ups
Speed, invisibility and snowballs are available as power-ups during matches, adding variety to rounds.
Spectator teleport
Eliminated players and spectators can be teleported to watch the match from a chosen position.

How it compares
Spleef Toys is open source under the GNU General Public License v3.0 only, runs as client and server, and covers 1.21 – 1.21.3, so it does not match SpleefWars' 1.21.11 build. PolarSpleef is server-side only, released under the MIT License, and targets 1.21.1 alone. The Block Shuffle is client and server, all rights reserved, and covers 1.21.8 – 1.21.11, overlapping with SpleefWars on the newest builds.
