Gem Runner is a fast-paced 3D endless running game where you sprint down a road packed with obstacles, coins, and rare diamonds, all rendered in smooth WebGL graphics right in your browser. Your job is simple: stay on the track, grab every gem you can, and survive as long as possible before speed gets the better of you. One bad dodge and it's game over – though you do get three extra lives to keep your run alive a little longer.

What makes Gem Runner addictive is how quickly the pace ramps up. The further you get, the faster the road comes at you, forcing sharper reflexes and smarter decisions about which pickups are worth the risk. The dynamic camera keeps the action tight and readable, while crash and reward sound effects give every close call and gem grab real weight. Controls are responsive and the game runs well on both desktop and mobile, so you can pick it up anywhere without losing feel.

It's a great pick for players who chase high scores, love collecting mechanics, or just want a quick skill-based game with no install required.
