We are Tumblix Studios. We build worlds kids can't put down, on Roblox, iPhone, iPad, Android and PC: heists, tycoons, dinosaurs, superheroes and moonlit towns. Scroll, and we'll show you one.
Chapter 01 // The Portal
One step, and you're somewhere else.
A kid walks out of a glowing gate onto an island in the clouds. Gold within reach, a waterfall at the edge. Five seconds in, there is already something to grab.
Chapter 02 // The Highway
Jump. Fall. Drive.
Off the edge, through the clouds, straight into a red convertible on a highway that glows. Every Tumblix world keeps you moving.
Chapter 03 // The City
Every door is a world.
Car washes, mega marts, cinemas and arcades. Look up: the Tumblix gate is open. Let's step into the real ones.
Chapter 04 // Heist / ActionLive
Shopping Cart Mayhem
Grab a cart. Rob the store. Outrun security.
Get a shopping list, steal everything from pizza to giant TVs, then shake the guards and escape to bank your haul. More loot means more heat: hide among shoppers, lose the guards, or ram your way out.
Chapter 05 // TycoonLive
Car Wash Tycoon
From one bucket to a neon street empire.
Start with a bucket and a $1 wash. Hire workers, build your car wash, then open a whole street of businesses: cafe, pizza, hotel, cinema, gas station, car dealership and more.
Chapter 06 // Adventure / CollectComing soon
Ride a Dino
Grab the eggs. Hatch the dinos. Ride them all.
Saddle up, ranger. Ride real dinosaurs through a huge wild valley, sneak eggs out of their nests before the parents catch you, hatch them at your ranch and raise a herd you can ride, from a tiny Compy to the T-Rex. For iPhone, iPad and Android.
Launching soonMission file
Chapter 07 // Superhero / CombatLive
Rift City Heroes
Suit up. Take flight. Stop the Rift invasion.

Chapter 08 // Co-op / AdventureLive
Moonbell Town
Restore the light. Bring tiny friends home.
Explore a moonlit town, restore its lost light and bring tiny friends home. Team up with up to four players across six rescue adventures, from pumpkin glasshouses to a runaway sleigh.

[02] // Capabilities
3D. 2D. Systems.
One small crew, the whole pipeline: world building, art, code, launch and live ops.
2D Art & UI
Key art, thumbnails, icons, HUDs and comic panels. The 2D that sells a world before the first click, and UI a kid reads at a glance.
Game Systems
Heists, tycoon economies, hatching and pets, combo combat, trading, store events. Written in Luau, tested headless and in Studio.
Live Ops & Data
Funnels on every first-session step, daily streaks, missions, seasonal chapters. Ship, read the data, fix the leak, ship again.
[03] // Protocol
How we build
Four rules every Tumblix world ships with. No exceptions, no dead air.
01
Hook in five seconds
Every world opens with something to grab, chase or steal before the player has read a word.
02
Something every few seconds
Events, combos, rewards, a light story. Attention on a phone is short, so there is no dead air.
03
Play it like a new player
We play each build at phone size as a first-timer and fix every unclear moment before launch.
04
Ship, measure, fix
Every step of the first session is a funnel event. When a step leaks, we fix that step and measure again.
