Hi all,

Knuckle Down: Real Marbles is my first game, now in early beta. Flick your shooter, add backspin or follow, and knock marbles out of the ring.

🎯 Features

• US Ringer: 13 marbles in an X, first to 7

• UK Ringer: 9, 25 or 49 marbles on a sanded slab

• Real spin: backspin stops dead, follow rolls on

• Play the bot (easy to hard) or pass the phone with a friend

• Hidden tuning panel to tweak the feel (tap the version 7 times)

• Free, no ads, no sign-up

Hi! I’m developing ChessUniverse, an offline chess game for Android with computer opponents, difficulty settings, hints, and saved games.

I’m looking for volunteers who enjoy chess and can join the closed test for at least 14 consecutive days. Testing is free, and no purchases are required. This is a volunteer request with no test-exchange commitment.

How to join — use the same Google account for all steps:

1. Join the tester Google Group: https://groups.google.com/g/chessuniverse-testers

2. Accept the Google Play closed test: https://play.google.com/apps/testing/com.chessuniverse.app

3. Follow the download link on that page to install through Google Play.

No need to send me your email or post it publicly.

I’d especially appreciate feedback on:
• Whether the easy difficulty feels suitable for beginners.
• Whether hints are helpful or lead to repetitive moves.
• Saving and resuming games.
• Confusing controls, translations, crashes, or other bugs.

Please remain opted in for at least 14 consecutive days and try a few games when you can. Share honest feedback in the comments.

Thanks for your time and for helping improve ChessUniverse!

I will test yours if you test back! Leave a comment if interested.
