Run a Firebase Remote Config A/B test targeted at a Google Analytics audience to validate a live-ops change before a full rollout

Steps

1. Define the Remote Config parameter(s) you want to experiment with (e.g., a difficulty tuning value or store price) and set a sensible default/control value in the Firebase console.
2. In the Firebase console, go to A/B Testing, create a new experiment, and choose Remote Config as the service to experiment with.
3. Set targeting criteria for the experiment — app version, country/region, and optionally a Google Analytics audience — combined with AND logic to scope who's eligible.
4. Define experiment variants with different values for the chosen parameter(s), set the traffic percentage split, and pick a primary metric to evaluate variant performance.
5. Start the experiment, monitor variant performance in the console as data accumulates, and roll the winning variant out to 100% of Remote Config once you have a statistically confident result.
