Never Twice
A calm memory game in space for players of all ages. Tap a planet you haven't tapped yet. After every tap the planets move and one more appears. Reach each galaxy's goal, and don't tap the same planet twice.
Ways to play
- Quick run: six galaxies, each with a goal and each harder to tell apart than the last
- Odyssey: nine galaxies in three sectors, with a boss galaxy at the end of each sector, a checkpoint, and twists: a bonus star to catch, drifting planets, spinning planets and eclipse shadows
- Daily Voyage: the same puzzle for every player, every day, with a day streak
- Rush: an optional 60-second sprint. Clear waves to win time back and see how many new planets you can pick before the clock runs out
- Practice: a gentle walk-through of the rule, whenever you want it
- Friend's seed: share a short code so a friend can play the very same galaxies
Shields and your star map
- A slip doesn't have to end your trip. On Easy you start with three shields, on Hard with one, and a cleared boss galaxy wins one back
- Every galaxy you clear lights a star on your star map. Grow from Cadet to Navigator, Pilot, Commander and Admiral, and earn a gold ring by clearing a galaxy on Hard

How to play
Tap a planet you haven't tapped yet. The planets move after every tap and one more joins, so you have to remember which ones you already visited.
Each galaxy has a goal: find that many new planets to clear it. If you tap one you've already tapped before the goal, you lose a shield, and when the last shield is gone the run ends. After the goal you can keep going for more points until a repeat ends the galaxy.
For parents
- No account, no chat. There is nothing to sign up for and no way to talk to other players. Scores, stats and your star map stay on the device.
- One quick question. On the first launch the game asks whether the player is 13 or older. The answer stays on the device. Younger players get child-directed, non-personalised, G-rated ads, no full-screen ads between runs and no rating prompt.
- Ads. The game is free with ads from Google AdMob, and an optional one-time Remove Ads purchase (through Google Play) hides them. An optional short video can earn one extra shield on Easy.
- Data. Basic gameplay events and crash reports go to Google Firebase to help us fix and improve the game; you can switch the usage data off in Settings. Remote Config fetches game numbers from Google. We collect no names, emails or locations.
- Reminders. The game can send one gentle Daily Voyage reminder, only if the phone's permission is allowed, and Settings can turn it off.
