Dead simple to play
Step into the ring, push your opponent out, win the round. New players get it in seconds — and keep coming back for the next match.


️ Multiple arenas, all at once
Run as many rings as your server can hold, each with its own game going at the same time. No queues, no "wait your turn." More arenas = more players having fun.


Stats that keep players hooked
Every win, loss, current streak and personal-best streak is saved forever. Players chase their records, climb back from defeats, and brag about their streaks.


A scoreboard that looks the part
A clean, real-time sidebar built on the modern Adventure engine shows the arena and live player count. Titles and action bars announce match start, the FIGHT, and the champion.


️ One-click arena selector
A built-in chest GUI lets players browse every arena and its live status with a single command — pick a ring and jump straight in.


Knockback you control
Tune the push strength, vertical lift and friction per arena. Make one ring a gentle nudge-fest and another a brutal launch pad. Your server, your rules.


Speaks every player's language
Ships with English and Italian, and each player automatically sees the game in their own client language. Add any language with a single file — untranslated lines fall back to English on their own.


Built to scale
SQLite works instantly with zero setup — perfect for a single server. Running a network or expecting thousands of players? Flip one setting for MySQL / MariaDB. Database access is fully asynchronous, so it never lags your gameplay.


️ Safe and worry-free
Player inventories are saved on join and restored on leave, elimination or disconnect — even after a crash. No fall, void, lava or hunger damage interferes with a match.
