Here's what each letter looks like when it's the broken one.
The FROG Method · Player Diagnostic
Four things make any game impossible to put down — and any offer actually work: Feedback, Rules, Opt-in, Goal. Miss one and the whole thing stalls, no matter how good the rest is.
I could never keep them straight, so I turned them into a frog. You're welcome.
Landed here from the scorecard? One of these four is where your game is breaking. Let's find it — so you stop fixing what was never the problem.
Here's what each letter looks like when it's the broken one.
Great games constantly show you you're winning — points, a filling bar, a level-up, a satisfying ding. That's what keeps your thumb on the controller at 1am.
Broken when
If people start and don't finish, it's not your ending. It's your feedback loop.
Constraints sound like the boring part, but they're why a game feels fair and doable instead of overwhelming. Your scope, your boundaries, your "here's exactly what this is."
Broken when
Too loose and they drown. Too tight and they suffocate. Either way, they bounce.
A game only works if you choose to play. Every click, every join, every buy is an opt-in. This is the one I see break most often, by a mile.
Broken when
It's not your course. Nobody's even seen it. It's the invitation.
Every game gives you something to chase — believable enough that you think you can do it, big enough that you actually want to. Get that balance wrong in either direction and nobody plays.
Broken when
Unbelievable, invisible, or not worth the trip — and nobody presses start.
One of those four stung a little more than the others. That sting is clarity.
You might be great at some of these — most people are. But one broken letter breaks the whole game. The best goal in the world can't save you if nobody opts in. Perfect opt-ins don't matter if your feedback loop lets everyone quit halfway.
You came in thinking the problem was your course, your website, your offer, you.
Turns out it's just a letter. And now you know which one.
That's what makes it fixable.
