Solar Expansion

Conquer 100 real star systems. No ads, no tracking, fully offline.

Command your fleets. Take the galaxy, one star system at a time.

Solar Expansion is a fast, elegant real-time strategy game built around our actual cosmic neighbourhood. Every one of the 100 levels is a real star system — Sol, Alpha Centauri, Barnard's Star, Trappist-1, Gliese 581 — with the planets and companions astronomers really found there.

The rules take ten seconds to learn. Planets you own grow ships. Send them to neutral or enemy planets to take those over. Whoever holds the system wins. What takes longer is getting good at it.

WHAT MAKES IT DIFFERENT

- No ads. Not a banner, not an interstitial, not a rewarded video. You bought the game; the game is what you get.

- No data collection. The app has zero permissions and cannot even reach the internet. Your progress lives on your device and nowhere else. Nothing is tracked, profiled or sold.

- No in-app purchases, no energy timers, no daily-login pressure. One price, everything unlocked as you play.

- Works completely offline. On a plane, in the car, in a basement — it does not care.

- Real astronomy. 100 systems from the real stellar neighbourhood, each with a short description of what actually makes it interesting.

- Three difficulty levels — Explorer, Captain, Admiral — so a seven-year-old and a grown-up can both find a fair fight.

HOW YOU PLAY

- Tap a planet to select it, double-tap to select everything you own
- Drag on empty space to box-select a group
- Swipe from planet to planet to open a permanent supply line
- Tap a target to send everything you have selected
- Slide the speed control if you want the battle to run faster or slower

BUILT FOR KIDS, PLAYABLE BY ANYONE

Solar Expansion is designed to be safe for children: no ads, no chat, no links out, no accounts, no data leaving the device. Nothing to buy once you own it. The abstract art style keeps the conflict bloodless — fleets of dots, not people.

Note: the game's interface is in Dutch.
