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. Drive into floating question-mark boxes scattered around the arena to receive a random weapon.

Your equipped weapon appears in the blue circle at the bottom-right of the screen. Press Space to fire it. Weapons fall into four categories: Smash Karts offers multiple modes beyond the starter Free For All. Select modes using the arrow next to "PLAY" on the main menu.

Every public match earns XP. Leveling up (max level 200) rewards you with coins, gems, hats, wheels, and character tokens. Use character tokens in the prize machine to unlock new characters with varying rarity levels.

Signing up via Google, Apple, Discord, or email grants 100 free gems immediately and enables cross-platform cloud saving.

The game features over 20 arenas including Kartuga, Toxic Towers, The Sand Box, Boneyard Basin, Snowpark, Skate Park, Lava Pit, Graveyard, Smash Fort, multiple Sky Arena variants, and seasonal maps.
