Terms of service

Last updated 28 October 2026. Plain-English draft; have it reviewed by a lawyer for the markets you sell in.

The game

KO Buddy is a cartoon boxing game for entertainment. Violence is cartoon-only. You can play without an account; linking X is optional.

Free play and purchases

Everyone gets free fights every day (currently 3, refilled at 00:00 UTC), a free first fight, a free first friend challenge and one free daily-boss attempt. You can buy extra fight credits and cosmetic items. Prices are shown before checkout; payment is processed by Polar as merchant of record, and local taxes may be added. You must be 18 or older to buy.

No prizes, no gambling

Nobody wins money or anything of cash value on KO Buddy. There are no stakes, wagers, bets or odds on results. Credits and cosmetics can only be used inside KO Buddy, have no cash value, and can't be withdrawn, sold, traded or transferred. Cosmetics never change gameplay.

Fair play

Leaderboards and the KO Wall use fights our server re-ran from your inputs. Don't cheat, automate play, or exploit bugs; we may remove results or accounts that do.

Names and the KO Wall

Pick a nickname that isn't offensive and doesn't impersonate anyone. Posting to the KO Wall is opt-in; you can take your posts down any time, and posts reported by several players are hidden. Don't use KO Buddy to harass anyone.

Changes

We may update these terms and prices; we'll change the date above when we do.
