What it is
Fast Rocket is a rocket-building and space-flight sandbox. Assemble a rocket from parts, launch it under a real rigid-body physics simulation, fly it to orbit with patched-conic orbital mechanics, plan manoeuvres, and land on other worlds. It is an original game with its own solar system, its own cast and its own parts.
What sets it apart is the welcome. Two voiced instructors, Ada (by the book, clipboard in hand) and Rivet (every problem needs a bigger engine or more duct tape), teach a complete beginner from "press SPACE" to a Moon landing and back. They argue, they joke, and they tell you exactly what to press while an arrow points at it. Every line is captioned, and every lesson is a real flight. Crashes teach ("Why did I crash?"), and every session ends with a reward.
The teaching does not stop when the lessons do: quick launch and free flight are narrated too, and in the builder you can tap a part twice and it goes in the right spot.
Features
Physics you can trust
Rigid-body dynamics, Tsiolkovsky delta-v, aerodynamic stability and heating. No wobble, no Kraken; when something fails, you can tell why.
Real orbital mechanics
Patched conics, manoeuvre nodes, transfers, captures and landings around nine worlds of the Helion system.
A builder that helps
Live delta-v, TWR and burn time per stage, symmetry up to 8x, undo and redo, and a Rocket Doctor that explains problems and offers one-click fixes.
Flight School
Eleven voiced lessons with objectives, hint arrows, press-this prompts and star ratings, from a controls tour to a Moon landing and a rendezvous in orbit.
Sandbox, Career-lite and Daily Challenge
Everything unlocked, or contracts and a tech tree, or a fresh seeded objective every day with streaks.
Juice and rewards
Countdowns, plumes, shockwaves, reentry glow, XP and ranks, mission-patch achievements and confetti.
Touch first, keyboard friendly
Every screen works on a phone. Full keyboard and mouse, gamepad support and rebindable keys.
Accessible
Captions on all speech, reduce-motion, a colour-blind-safe palette, UI scale and full touch controls.
Offline and private
Single player, no account, no ads, no tracking. Your progress stays on your device; anonymous diagnostics are off unless you choose to share them.
