FAQ

What do players ask about Be Dino 🦖 - Jurassic Dinosaur Simulation?

What do you do in Be Dino?

You play as a dinosaur on Roblox, eat food and smaller dinosaurs to raise Size, avoid anything with a higher Size, and collect dinosaur cards in the Dinodex. The developer is Nibblebyte.

Where do I enter codes?

In the lobby, open Shop on the left, choose the Code tab, paste the code, and press the green Redeem button. A retired code can reply Code has expired. Each code works once per account.

Which codes were still listed in late September 2026?

AERIAL, WEATHER, HUGE150K, and AMBER. Gem amounts are consistent on those reports. Several dinosaur rewards are not, so read the in-game pop-up.

Can I change dinosaurs during a run?

No. Return to the lobby and use Swap Dino. Entering the green portal always starts that run at Size 0.

Should I pay Gems when I die?

KEEP SIZE is 35 Gems and keeps your Size. REVENGE is 70 Gems and chases the dinosaur that ate you. Declining is free and resets you to Size 0. Keep Size is the better buy on a long run.

Ready to play Be Dino 🦖 - Jurassic Dinosaur Simulation?
