Welcome to the Ninefold closed test!
Ninefold is a set of short brain-training games in nine skills (memory, attention, speed, logic, numbers, spatial reasoning, words, planning and problem solving), with a daily workout picked for you. No account, no ads; your progress stays on your phone.
How to join the test (2 minutes)
- Click Join group above, using the same Google account as your Play Store.
- Opt in: https://play.google.com/
apps/testing/com.vytzab. → Become a testerninefold - Install: https://play.google.
com/store/apps/details?id=com. vytzab.ninefold
If the install page says "not found", wait a few minutes after opting in, and check you're signed in with the same account.
Please stay for 14 days. Google requires 12 testers to stay opted in for 14 days in a row before the app can be released. Keep it installed; playing now and then is plenty, and a daily workout takes about 5 minutes.
Unlimited for free: please don't buy Unlimited during the test (it's a real charge). Ask the developer on Reddit for a free code instead; it's yours to keep.
Feedback: in the app, More → Send feedback, or reply on Reddit. Bugs, confusing moments, games that feel too easy or too hard: all welcome.
Privacy: group members are hidden from each other; only the developer sees who joined. Nobody posts here, so you won't get emails, except an occasional note when a new test version is out.
Thank you for helping!
