World.io

World.io is a territory conquest game on Roblox by Studio Inked that applies the classic .io game format - think agar.io and slither.io - to a global political map. Players control a nation and expand their territory by consuming smaller countries while avoiding larger ones, racing to dominate the server in six-player matches. Launched in March 2025, the game has achieved 153 million visits and 4.38 million favorites in just over a year, making it one of the fastest-growing Roblox games of 2025 to 2026.

Each server holds only 6 players, creating focused matches where every rival is visible and every conquest decision matters. Cash is the primary currency, earned by expanding territory and spent on upgrades. Premium players receive a 1.5x Cash multiplier that compounds over a session, making early expansion more efficient. Private servers are completely free, offering a safe environment for friends-only matches without open competition:

• 🗺️ Territory Conquest - expand your nation by consuming adjacent smaller countries on the global map
• 🏆 PvP Dominance - eliminate rivals to grow unchallenged as the match progresses
• 💰 Cash Economy - earn currency from territorial growth and spend it on upgrades
• 🗺️ Free Private Servers - invite friends for matches without public competition

Session progression is self-contained - there is no persistent ranking system that carries across games, keeping every match a fresh start. The 6-player format means matches are short and intense, which drives the game's enormous replay value and explains its 4.38 million favorites compared to 153 million visits.

Studio Inked has been actively updating the game through April 2026, and the free private server model has driven significant organic social sharing and content creation around the game.
