Step 1: tap Join group, signed in with the Google account your Play Store uses.

Step 2: on your Android phone open https://play.google.com/apps/testing/com.nimbleknot.logictrio and tap Become a tester.

Step 3: tap Download it on Google Play, and install.

Play says "not found" or "not available"? Check that your Play Store uses this same Google account (your picture, top right), wait 10 minutes, then tap the link again.

Please stay in this group and keep the game installed until we post here that the test is over (about 3-4 weeks), and play a few minutes on most days. Ads will show. Please don't tap them just to help us (Google treats that as fraud). Watching a hint video is fine.
