🎮 Bundle Checker

Copy your profile URL (easiest)
Open Steam → click your name (top right) → View my profile → copy the URL from your browser's address bar. It will look like https://steamcommunity.com/id/yourname or https://steamcommunity.com/profiles/7656…

Use the Steam app
Open Steam → click your name → Account details → your SteamID64 is the long number in the URL.

Use steamid.io
Go to steamid.io, search your Steam name, and copy the steamID64 number.
