TWAIN
One swipe. Two worlds.
Every swipe moves two characters in two different worlds. One hits a wall, the other keeps going — use that to line them up and bring both home at the very same moment.
How to play
Swipe up, down, left or right. Both characters try to move that way at the same time. Get both onto their green exits on the same swipe.
Two at once
A character that hits a wall stays put while the other keeps moving. Walls are your best tool for lining them up.
Mirror worlds
In a purple world left and right are swapped: swipe right and that character goes left. Up and down stay the same.
Ice worlds
In a teal world the character slides until it hits a wall. It needs something in front of it to stop.
Holes
Don't step into a hole. If a move would drop a character in, it bounces back and the move is undone.
Three stars
Finish in the shortest number of moves for three stars. Every level is checked by a solver, so the target is always reachable.
45 levels, 14 languages
A gentle start, then mirror, ice and holes mixed together. Play in English, Türkçe, Deutsch, Français, Español, 日本語, 한국어, 中文 and more.
Support
Stuck, found a bug, or have an idea? Here are quick answers — and we read every email.
I'm stuck. How do hints work?
Tap the light bulb. It draws the full solution from where you are: dotted paths on both boards and the swipes to make at the top. Follow it and the path advances with you; make a different move and it disappears.
Your first hint is free. After that, each hint is unlocked by watching a short, optional ad. A level solved with a hint gives at most 2 stars.
How many undos do I get?
Each level gives you a few undos: 2 in levels 1–5, 3 in levels 6–10 and 4 after that. The number is shown on the Undo button.
When you run out, you can watch a short, optional ad for 3 more undos on that level. Restarting a level is always free.
How do I get 3 stars?
Finish in the target number of moves shown at the top — that is the shortest possible solution. Up to 3 moves more gives 2 stars; any solution gives 1 star.
Why do I see ads?
Twain is free to play. Occasionally, after you finish a level (not in the first levels), a full-screen ad may appear. Rewarded ads for hints and undos are always your choice.
I lost my progress.
Progress is saved on your device only. It is removed if you uninstall the game or clear its data, and it does not move between devices.
How do I change my ad privacy choices?
In the EEA, the UK and Switzerland, tap Privacy on the game's title screen to reopen the consent form. On Android you can delete or reset your advertising ID in Settings → Google → Ads (or Settings → Privacy → Ads). On iOS go to Settings → Privacy & Security → Tracking. See the Privacy Policy for details.
How do I request deletion of my data?
We don't keep identifiable data on our own servers. Email us and we will help with any request involving our advertising and analytics partners.
Can I change the language?
The game follows your device language when it is supported. You can change it any time with the language button on the title screen.
Please include your device model and the level number.
Privacy Policy
In short: Twain has no accounts and never asks for your name or email. Your progress stays on your device. The free game shows ads from Google AdMob and uses Google Firebase to count how levels are played and to report crashes. These services may use device identifiers as described below. Where the law requires it, you are asked for consent first, and on iOS you can decline tracking.
1. Who we are
Twain ("the Game") is developed and published under the SolidProd brand by Elizan Media Organizasyon Ltd. Şti., a company registered in Türkiye ("we", "us", "our"). We are the data controller for the processing described in this policy. Contact: twain@solidprod.com.
2. What we do not collect
The Game has no sign-up or login. We do not collect your name, email address, phone number, contacts, photos, precise location or payment details. Your level progress, stars, remaining free hints and settings are stored only on your device and are deleted when you uninstall the Game. We do not run our own servers for the Game.
3. Third-party services and the data they process
To keep the Game free and improve it, we use the services below. They process data under their own terms and privacy policies, as independent controllers or as our processors.
| Service | Purpose | Data processed |
|---|---|---|
| Google AdMob | Showing and measuring ads (including optional rewarded ads), frequency capping, fraud prevention | Advertising ID (Android Advertising ID; Apple IDFA only if you allow tracking), IP address, device and app information, ad interactions |
| Google User Messaging Platform | Asking for and storing your consent choices | Your consent choices, device and app information, approximate region |
| Firebase Analytics | Understanding, in aggregate, which levels are too hard or too easy and how features are used | Game events (level started, completed or restarted; moves, stars; hint used; ad watched), app-instance ID, device model, OS version, language, approximate country |
| Firebase Crashlytics | Finding and fixing crashes | Crash traces, device state at the time of a crash, installation ID |
| Unity (game engine) | Running the Game | Limited technical data such as device model and OS. We do not enable Unity Analytics or Unity Ads. |
More information: How Google uses information from apps that use its services · Google Privacy Policy · Firebase privacy · Unity privacy.
4. Consent and your choices
- EEA, UK and Switzerland: before personalised ads, the Game shows a consent form (Google User Messaging Platform). You can accept, reject or choose specific purposes, and change your choice later with the Privacy button on the title screen. If you reject, you may still see non-personalised ads.
- iOS: the Game asks for permission through Apple's App Tracking Transparency prompt. If you choose "Ask App Not to Track", your IDFA is not shared.
- Android: you can delete or reset your advertising ID, or opt out of ads personalisation, in your device settings (Google → Ads, or Privacy → Ads).
- Rewarded ads are optional: ads for extra undos or hints are only shown when you choose to watch them.
5. Legal bases (GDPR, UK GDPR, KVKK)
We rely on your consent for personalised advertising and, where required, for analytics; on our legitimate interests in keeping the Game working, secure and free of fraud (crash reports, ad fraud prevention, non-personalised ads); and on contract performance for any purchase you make. You can withdraw consent at any time as described above; this does not affect processing before the withdrawal.
6. US state privacy rights (including California)
We do not sell personal information for money. Showing personalised ads through Google AdMob may be considered "sharing" or "targeted advertising" under some US state laws. You can opt out by deleting your advertising ID or opting out of ads personalisation on Android, or by turning off tracking on iOS. Residents of California and other states with privacy laws may request access to or deletion of their personal information by emailing us; we will not discriminate against you for using these rights. We do not use or disclose sensitive personal information.
7. Children
The Game is intended for a general audience and is not directed to children under 13 (or the higher minimum age in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will take steps to delete it.
8. Retention, transfers and security
We do not keep personal data on our own servers. Firebase Analytics data is kept for no more than 14 months; Crashlytics crash data for up to 90 days; AdMob data according to Google's policies. Our providers may process data outside Türkiye and outside your country (for example in the United States); such transfers rely on the providers' standard safeguards, such as Standard Contractual Clauses. Data is transmitted over encrypted connections.
9. Your rights
Depending on where you live, you may have the right to access, correct or delete your personal data, to restrict or object to its processing, to data portability, and to complain to a data protection authority (in Türkiye, the Personal Data Protection Authority — KVKK; in the EU, your local authority). Because we do not hold identifiable data ourselves, the fastest route is usually your device settings described above. For anything else, email twain@solidprod.com and we will respond within 30 days.
10. App permissions
The Android version requests internet and network-state access (to load ads and send analytics) and the advertising ID permission. It does not request access to your location, camera, microphone, contacts or files.
11. Changes to this policy
We may update this policy, for example when we add a new service. The effective date at the top shows the latest version. Significant changes will be announced in the Game or on this page.
