1) Pick a Polygon-friendly gambling site and acquire POL on a reputable exchange. 2) Register an account (some sites only need email + password). 3) Deposit using Polygon: copy the site’s wallet address, send POL from your wallet, and wait for confirmation. 4) Claim promos if available (some require opt‑in or a code). 5) Play: slots, table games, live dealer titles, crash games, and sportsbook markets are common. 6) Withdraw: submit your Polygon address and amount; many sites process crypto payouts quickly, but timings can vary by platform and checks.
