Games Like Clickstellar

Tap a star. Build a galaxy.

Clickstellar is a cozy sci-fi idle clicker about the biggest number of all: a star's

output. Tap a lone world to harvest Energy by hand, then let an ever-growing empire of

reactors and megastructures pour it out for you  even while the game is closed.

Every tap is a spark. Land a critical SURGE, chain combos, and watch your Energy per

second climb from a trickle to an astronomical torrent.

Spend Energy on a deep tier of structures: Solar Collectors, Fusion Reactors, Antimatter

Cores, Dyson Swarms, Nebula Extractors, Pulsar Arrays, Quasar Engines and beyond. Buy one at

a time, in tens, MAX, or fill straight to the next ×25 milestone.

Comets streak across the void, catch them for Frenzy multipliers, instant Windfalls, free

structures, and rarer surprises. Blink and you'll miss them.

When your world can give no more, collapse your entire empire into Dark Matter, a

permanent boost to every future run. Each ascension reforges your planet into a brand-new

star (cycling nine stellar types) beneath a shifting nebula sky. Spend Dark Matter on a

sprawling prestige tree: sharper taps, cheaper structures, and full automation, an

Auto-Harvester that taps for you and a Foreman that buys the best value on its own.
