The SDK keeps an anonymous player identity (an “ARCADE_KID”-style nickname) cross-game. You use it for submitScore, persistRun and to show “Hi, ARCADE_KID” in your UI. The first time a visitor touches any game, a modal asks for the nickname. After that, no more prompts on any game on the platform.
The full API reference (getPlayerName, setPlayerName, ensurePlayerName, sanitizeName) and edge cases are in the Spanish version.
