About Pen Fight

Last updated: 14 September 2026

Pen Fight is a free browser game operated by LetsCrak in Sri Lanka. It brings the school-desk pen game to phones and computers: flick your pen, knock theirs off, and keep yours on the desk.

What you can play

Play solo through eleven named introductory opponents and continue up the generated bench, or try the daily desk challenge. Earn stars through play to unlock pens with different handling.

Online rooms support up to four people on separate devices. Send an invite link or share a room code, and use optional voice chat while you play. A completed round can be shared as a replay link. Anyone receiving that link can watch or forward it.

No installation or account is required to start playing.

Development and credits

The project began from the penfight.xyz web prototype. This version includes work on browser multiplayer rooms, progression, voice connections and replay sharing. The classroom game itself belongs to many groups of players, whose house rules can differ.

The 3D view uses three.js and the simulation uses Rapier. Shots are simulated rather than selected from a set of animations. Read the pen comparison for the recorded balance experiment, its method and its limits. The experiment measures bot-driven play, not a guarantee about a human player's results.
