Smash Karts is a 3D multiplayer IO kart battle game where you drive into arenas packed with real players, grab randomized weapons from loot boxes, and blow up as many opponents as possible in intense three-minute rounds.

Level up to unlock 187 characters, dozens of cosmetics, and multiple game modes — all playable free in your browser on PLRun with no download required. Smash Karts (SmashKarts.io) is a multiplayer online kart battle arena game developed by Tall Team, a Dublin-based indie studio.

First released in March 2020 and continuously updated through March 2026, the game has earned a 9.1/10 rating from over 233,000 votes on CrazyGames and over 1 million mobile downloads. Unlike traditional racing games, the goal is not to cross a finish line — it is to destroy other players' karts using weapons collected during combat.

Matches support up to 12 players in Free For All or 8v8 in team modes, with rounds lasting just three minutes. The game features smooth arcade-style kart handling, colorful cartoon 3D visuals, and an enormous customization system with hundreds of cosmetic options. As an HTML5 browser game, it runs on desktop, mobile, and tablet, and supports cross-platform saving and controller input.

It is also available on iOS and Android. Every match drops you into a closed arena with other online players. Grab weapons, eliminate opponents, and finish with the highest score before the timer runs out. Controller support is available — enable it in Settings > Controls by ticking "Gamepad Controls." On mobile/tablet, the game uses on-screen buttons.
