About Dinosaurs.io: Grow the Biggest Tyrannosaurus

Dinosaurs.io drops you into a competitive arena where the goal is simple and relentless: grow your Tyrannosaurus to the largest size possible by eating humans, building mass, and taking down rival dinosaurs smaller than you. The pace is direct — eat, grow, dominate. Several scenes show dinosaurs each encircled by a glowing green ring at their feet. Small yellow humanoid figures are scattered across a gray and white checkered surface. In one scene, a side of the checkered arena is bordered by a wall of green blocks and a large body of blue water.

How to Play Dinosaurs.io

The core loop revolves around mass. Eat little men to increase your mass, and once you are larger than a rival dinosaur, attack it. Avoid any dinosaur that currently has more mass than you — those encounters go the other way. Keep eating humans to keep growing, and work toward becoming the winner of the arena.

Controls

• Touch (finger): Manage your dinosaur's movement
• Mouse: Manage your dinosaur's movement
