Thank you for helping test Lapilli Stones — a board game of five-in-a-row and captures, played with glass beads on a Roman wooden board. This page walks you through everything, step by step. No technical experience needed.
First time hearing about Lapilli Stones? Read the story of the game — where it comes from, how it's played, and how it outlived a volcano.
Everything is free. Testing costs nothing and nothing you do can break anything on my end — that's the point of testing.
↑ back to topI need to add you to the tester list by email. Send me:
Send it to: lapilli-stones@proton.me — a short note saying you'd like to test is plenty. Mention which devices you play on (iPhone, iPad, Mac), and if you found your way here from a forum or a friend, say hello; every tester so far has shaped the game.
Once I've added you, Apple will send you an invitation email titled something like "Eddie Merkel has invited you to test Lapilli Stones." It can take a few minutes to arrive. Check spam if it doesn't.
↑ back to topTestFlight is Apple's official app for testing apps before they reach the App Store. It's made by Apple, it's free, and it's safe.
iPhone / iPad
Open the App Store, search for TestFlight, and download it (blue icon with a white propeller).
Mac
Open the App Store app on the Mac, search for TestFlight, and download it.
Installing on more than one device? Just open TestFlight on each device (signed in with the same Apple Account) — Lapilli will be there waiting. No need for a second invitation.
When I release a new test version, TestFlight will notify you. Open TestFlight and tap Update — your saved games survive updates.
↑ back to topYou only need this for online play — playing me (or another tester) remotely, one move at a time, like chess by mail. Solo play works without it.
iPhone / iPad
Open Settings, scroll down and tap Game Center, and turn it on. It uses your Apple Account; you can pick a player nickname.
Mac
Open System Settings, type Game Center in the search box, and sign in there.
Online games between us need a Game Center friendship first — and the email you sent in Step 1 is all it takes. I'll send a friend request to that same Apple Account; accept it when it arrives (as a notification, or under Settings → Game Center → Friends on iPhone/iPad). A nickname alone isn't enough — Game Center has no name search; friendships travel by invitation.
Open Lapilli. A short interactive tutorial appears automatically and walks through every rule — placing stones, winning with five in a row, capturing pairs, the rule variants, and online play. It takes about three minutes and you can bring it back any time from Settings → Show Tutorial.
Then play! Start with a game against the computer on Beginner (the gear icon opens Settings, where you pick your opponent), and work up from there.
↑ back to topPlay however feels natural — the most valuable thing you can do is simply use the app and notice when something surprises, confuses, or annoys you. If you want a checklist, here's where fresh eyes help most:
Everything is welcome — bugs, confusion, wishes, complaints about the bird sounds. Small observations included; "this felt weird" is a useful report.
iPhone / iPad
While you're in Lapilli, take a screenshot (press the side button and volume-up together). Tap the little preview in the corner, and you'll see a Share Beta Feedback option — it sends the picture straight to me with your comments attached. You can even draw on the screenshot to circle the problem.
Or: open TestFlight, tap Lapilli Stones, and tap Send Beta Feedback.
Mac
Open TestFlight, select Lapilli Stones, and click Send Beta Feedback. Attach a screenshot if you can (press Shift-Command-3 to take one).
TestFlight will notice and offer to send the crash to me automatically, with a box for you to say what you were doing. Please write even one sentence — "I had just captured a pair and hit Undo" turns a mystery into a fix.
lapilli-stones@proton.me — for anything, any time, in any format.
1. What you did 2. What you expected 3. What actually happened.
"I tapped Play Online, expected something to open, and nothing happened at all" is a genuinely excellent bug report. (It's also a real one — a tester's report exactly like it caught one of our best bugs.)
Thank you. Genuinely. Every game you play makes this one better.
