Space Clicker Game

Play Space Clicker free online. Mine Stardust, automate production, manage Heat Flux, catch Golden Comets, and reset for permanent Dark Matter upgrades.

Space Clicker is a free browser-based incremental space game. Galaxy Miner is the flagship mode: mine Stardust, automate production, manage Heat Flux, and use Galactic Reset for permanent Dark Matter upgrades. The site also includes five separate space simulations plus Spacebar clicker, counter, and CPS tools.

How to play Space Clicker

  1. Mine Stardust manually to start the run.
  2. Buy Mining Drones, Rovers, Bases, Orbital Stations and Dyson Swarms for automatic production.
  3. Keep active mining between 80% and 99% Heat to use the 2x Heat Flux bonus without overheating.
  4. Reach 40 billion current Stardust for the first Dark Matter; 1 trillion awards 5.

What Space Clicker Game includes

SpaceClickerGame.com combines the flagship Galaxy Miner progression loop with five separate browser simulations and a dedicated Spacebar tool suite. The six simulations use different mechanics instead of presenting the same click loop under different names.

You can manage life support in Mars Colony Idle, defend a mothership in Star Defense, merge and deploy ships in Merge Spaceships, experiment with orbital projectiles in Gravity Idle, or decode transmissions in Deep Space Signal.

The Space Clicker progression loop

Galaxy Miner starts as an active space clicker: each deliberate input produces Stardust and raises Heat. As automation upgrades accumulate, passive production becomes a larger part of the run. Heat Flux rewards active timing between 80% and 99% Heat, while Galactic Reset turns sufficiently large runs into permanent Dark Matter progression.

The dedicated Galaxy Miner page explains its Heat, planet, automation, offline-production and Dark Matter systems in more detail.

Spacebar games, counters and CPS tests

The Spacebar Games hub separates several different keyboard intents. Spacebar Clicker is an upgrade-based incremental game, Spacebar Counter keeps an untimed press total, and Spacebar Clicker Test measures timed or click-target CPS. Spacebar Clicker 2 uses a separate progression tree with Overdrive and Nova Core ascension.

Play instantly in your browser

No account or download is required for the current games and tools. Supported progress is stored locally in the current browser rather than a cloud account, so clearing site storage or changing devices can separate or remove local progress. Portable backup options are available in Galaxy Miner, Spacebar Clicker, and Spacebar Clicker 2.

Idle progression and mobile play

Galaxy Miner begins with manual mining and shifts toward automated production. Returning after time away can credit up to 24 hours of saved automatic production. Touch controls are available in modern mobile browsers, while Spacebar tools provide on-screen controls for devices without a physical keyboard.

Strategy, mobile play, and related tools

Read the Space Clicker strategy guide for upgrade and Galactic Reset planning, or use the Galaxy Miner milestones page to review visible Stardust, automation and Dark Matter thresholds. For keyboard-focused play, open Spacebar Clicker, the Spacebar Counter, or the Spacebar Clicker Test. The main game and Spacebar suite include touch controls for mobile browsers.
