Swordz.io
Swordz.io is a PvP arena where your weapon is your progress bar: collect food, defeat monsters and players, and watch your sword grow from a dagger into a ridiculous cleaver that clears half the screen.
How to Play
Roam the map slashing monsters and rival players. Everything you defeat drops food that feeds your sword's growth — and a bigger sword means longer reach and heavier damage. Die and you drop your progress for others to feast on, so every fight is a gamble.
Controls
Move: Mouse
Attack: Left mouse button
Sprint: Right mouse button / Space (if available)
Reach Is King
The genius of Swordz.io is that power is literally visible: you can see exactly how far every enemy's blade swings. Fights become geometry — staying one pixel outside their arc while they're inside yours. Monsters and dragons offer safer growth than PvP, but player kills pay far better.
Tips
Never trade swings with a longer sword; make them whiff first
Farm monsters until your reach can compete
Back away mid-swing to bait attacks, then punish the recovery
Fresh-spawn zones are for farming, not bullying — the food is elsewhere
Big sword players are slow to turn: circle them
