Solar Puzzles
Space puzzles for young astronauts
Five gentle puzzle games and a museum of the whole solar system — every planet and all five dwarf planets, with real photographs and honest facts. No harsh "game over", no ads, no sign-in. Just space.

Five puzzles and a museum
Every game is easy to pick up, forgiving by design, and quietly teaches the solar system. Clear every level you can reach in Planet Trails, Crystal Hunt, Planet Rescue or Cosmic Marbles and a Mystery Flight is made up just for you, three a day. The games also share one tank of five hearts: a lost run costs one, and a heart comes back every 20 minutes on its own — the wait the free game has always kept. No heart is ever sold on its own.
Planet Blocks
Drag glowing planet pieces onto the star grid and fill rows to burn them. An endless mode where the difficulty grows with the score instead of arriving all at once, and Crystal Hunt: forty pixel pictures built of blocks, with crystals and stardust to collect. The eight Training pictures are free; the rest come with the Space Pass.
Planet Rescue
Forty handcrafted missions where planets are trapped or frozen in the field. Clear the right lines to set them free — a puzzle with a rescue story attached.
Planet Rescue is also a YouTube Playable: play every mission free on YouTube, where YouTube may show an ad between missions.
Planet Portals
Forty levels of sliding blocks into matching portals, from first steps to genuinely tricky. Plus a Puzzle of the Day with a streak, and a pass-and-play duel for two.
Cosmic Marbles
Match three planet marbles before the chain reaches the black hole. The hole spins faster as danger grows — and the chain slows down to give small hands a real last chance.
Planet Trails
Draw one unbroken flight through every sector of a sky chart, touching the beacons in flight-plan order and landing on the world the trip is for. Forty charts, no clock, and nothing you can get wrong — a wrong move simply does not happen. The first eight charts are free; the rest come with the Space Pass.
Planet Trails is also a YouTube Playable: fly every chart free on YouTube, where YouTube may show an ad between charts.
Space Museum
Star points earned in any game unlock worlds in the museum: eight planets, five dwarf planets and rare artifacts to find, each with one honest fact and a real photo wherever one exists. Jump on any world with ground to stand on, and fly real spacecraft missions along their true routes.
Safe by construction
No ads, no accounts, no analytics, no tracking, nothing collected. The games play entirely offline; the only moment the app uses the network is paying for the optional Space Pass, and that goes through Apple or Google, who never hand us a payment detail. Buying sits behind a grown-up check.
Native on iPhone, iPad & Android
Two native codebases, one game — because a puzzle board that stutters isn't fun for anyone.

Built for one very demanding player
Solar Puzzles started as a birthday project for a six-year-old in the family who can name all five dwarf planets and will absolutely tell you when something is wrong. That's why Ceres sits between Mars and Jupiter where it belongs, why the facts are real, and why worlds nobody has photographed up close — Haumea, Makemake — say “no real photo exists yet” instead of showing invented art. Imagery comes from NASA and other public-domain sources, credited in the app. She approved the release. Eventually.
Hand them the whole solar system
Free on the App Store and Google Play, and the free game stays exactly as it was. No ads, no sign-in, nothing collected, and every puzzle plays offline. Five shared hearts keep the pace gentle, one coming back every 20 minutes as it always has. There is one optional subscription, the Space Pass, which opens the rest of Planet Trails and Crystal Hunt, Mystery Flights without a daily limit and a deeper museum — it sits behind a grown-up check, and no heart is ever sold on its own.
