Infos zum Spiel

Pebble to Star is an idle growth game.

Pull in the bodies that drift past and raise a grey pebble into the world you want: a planet, a star, a black hole, a galaxy.

You start as a grey rock in a 1-bit sky. Nothing is timed. What you eat decides what you become.

Left-click to pull, right-click to push

Left-click a comet or a meteor and it falls in, leaving a crater. Hold the left button and sweep to take whatever the cursor passes. Right-click what you don't want and it is flung away. Anything flashing red is on a collision course: take it, or push it off. The heavier you grow, the more your gravity pulls in by itself, and it keeps eating while you are away.

Become the world you want

Open the growth route and pick a destination: an ocean world, an iron planet, a blue giant, a magnetar. A checklist in the corner shows what is still missing. Ice makes oceans and metal makes iron worlds; the mass you ignite at decides what kind of star you become, and how it dies.

From 1-bit to 24-bit

The screen starts in 1-bit black and white. As heat, water and life build up and you grow from layer to layer, it gains colour depth bit by bit, until oceans, clouds, rings and nebulae show in full colour.

Events ask you to choose

A neighbouring planet swings past: move inward, move outward, or hold your orbit. The Sun falls toward you: merge, or push it away. A planetary embryo the size of Mars is aimed at you: a grazing hit makes a moon, and melts the whole surface. Every layer brings choices like these, all the way up to colliding galaxies.

A civilisation, from first light to last

Keep a living world stable and a civilisation appears: you can see its lights. Then it reaches outward: telescopes, satellites, a space station, starships. But one big impact throws it back into a dark age, or ends it and leaves only ruins.

In the game:

• - Grow from a pebble all the way to a galaxy, with a new look and new events at every stage

• - Dozens of destinations: worlds, stars, stellar remnants and galaxies, each with its own conditions

• - A star map with dozens of upgrades across several branches, bought with the elements you eat

• - Several kinds of life, and more than one way for a civilisation to leave its planet

• - Modelled on current astrophysical theory and observations: stars die the way real stars do, every event is based on a real object, and the black hole is ray-traced through curved spacetime

• - A codex of 100+ worlds and phenomena, and an in-game camera for the moments you want to keep

• - If you like collecting: fill the codex and the periodic table

• - Complete the periodic table and you can refuse the bounce: watch the universe age all the way to heat death

• - Big Bounce: collapse the universe and start again with a periodic table that keeps your progress

• - Let it grow on its own: switch on idle and it keeps eating while you are away; growing up waits for you. Sometimes letting go is a choice to

How far can your pebble grow?

AI tools were used to assist in drafting the written text of this game (in-game explanations, codex entries, the four language versions of the interface, and store page descriptions); all such text was reviewed and edited by the developer. All artwork is procedurally rendered by shaders written by the developer, the store capsule artwork was commissioned from a human artist, and all sound is synthesised by the developer's own code. The game does not use AI to generate any content at runtime.
