Kart Bros guide
Kart Bros is Blue Wizard's kart racer and the only Bros game still in early access — which is exactly why it changes faster than any other title in the series. Version 1.82 added a full track editor and online Bro Cup, and updates keep landing.
The state of the game
Kart Bros is in active early access as of late 2026, and the pace of change is the defining fact about it. The v1.82 release (October 26) shipped three things at once: a track editor that lets players build courses, a community track system that publishes those courses to everyone, and an online Bro Cup. Most info sites covering the game froze months ago; anything you read elsewhere should be checked against the update tracker on this site, which follows the official changelog.
Modes
The current mode lineup: Quick Play against the CPU, Time Trial for solo practice and leaderboards, online racing with up to six players, and the Bro Cup — a season-style tournament, now playable online since v1.82. Each mode exercises a different skill: Quick Play teaches the tracks, Time Trial teaches the racing line, online teaches you that humans block on purpose.
Boost without cooking yourself
The boost system has a heat mechanic — hold boost too long and you overheat, losing the speed advantage exactly when you need it. The winning habit is pulsing: short boost bursts on straights, releasing before the meter climbs into the danger zone, rather than pinning the button. Combine with the drift system (which charges boost on good drifts) and the rhythm becomes: drift into corners, bleed the meter on straights, never max the heat.
Characters, honestly
Five characters are publicly confirmed — Dole, Earnhard Jr., Miss Meow, Space Cadet, and Invader Zip — but the full roster is larger, and real performance stats for every character are not published anywhere official yet. Rather than invent stat tables like some sites do, this guide holds off on rankings until data is verifiable. If you want to help document the roster, screenshots from the character-select screen are the reliable source.
Where to play
The official home is kartbros.io — a single-page site that loads the game directly, no install. Like the rest of the series it is free and runs in the browser; Chrome is the only officially guaranteed browser. Restricted-network access options are on the unblocked page.
