SIERRA3 the Game
A fast-paced arcade flyer built by second-grade creators and brought to life by RJF Studios.
Tap to Fly
SIERRA3 is a one-tap arcade flyer set in deep space. Tap to keep your ship climbing and weave through the asteroid lines ahead. The rules are simple — but finding the rhythm takes real skill. "One more run" quickly becomes ten.
Your Journey Begins
Every run starts gentle and never stops climbing. Drift through quiet star fields, then push into denser asteroid fields, enemy patrols, and the high-stakes Galaxy and Universe Challenges. How far into the unknown can you get?
Learn the Flow
Calm Winds offers the most forgiving environment to start your journey. The skies are clear, the rhythm is steady, and every tower is a chance to improve your timing. Perfect your tap control and build the reflexes you'll need for tougher challenges.
The Field thickens
Push farther and space pushes back: asteroid lines close in, enemy ships sweep the lanes, and the margin for error shrinks. Grab a power-up, raise your shield, and hold your nerve.
You Crashed!
Clip an asteroid or get run down and the run ends — but never for long. Your best score is always sitting there waiting to be beaten, and a fresh launch is one tap away.

Built with Heart
SIERRA3 is the first game from RJF Studios, dreamed up by a second grader and his friends — with a loving family helping out a little bit too.
