Short answer — as of 2025 the most widely recommended no‑deposit casino bonuses for US players come from the licensed casino brands (BetMGM, Borgata, Caesars) plus several sweepstakes/sweeps casino sites. Availability and exact amounts depend on your state, so check terms before signing up. Sources below. (PokerNews.com)

Top no‑deposit offers to look for in 2025 (what reviewers are naming “best”)

• BetMGM Casino — $25 freeplay (new accounts in regulated states such as NJ/PA/MI; some states like WV have slightly different offers). Good brand, redeemable immediately for eligible games; usual playthrough/expiration rules apply. (PokerNews.com)
• Borgata Casino — ~$20 freeplay for new US accounts in regulated states (NJ/PA/MI). Same parent group as BetMGM and similar terms. (PokerNews.com)
• Caesars (select states) — small no‑deposit or low‑deposit freeplay (often $10 free slots credit) during some months. Check the current welcome page for your state. (Insider-Gaming.com)
• Sweepstakes / “sweeps” casinos (Rush, Chumba, Pulsz, WOW Vegas, LoneStar, etc.) — offer free/sweeps coins that don’t require a real‑money deposit and are available in many US states where regulated real‑money casinos aren’t. These are a different model (two-currency system) but are useful if you want free play without state restrictions. (PokerNews.com)
• Smaller/new brands (Stardust, Stardust‑style niche sites) — sometimes give free spins on signup (e.g., 25 free spins on a single slot). These can be good for slots but often carry higher playthrough limits. (Insider-Gaming.com)

Important points and how to pick the best one for you

• State matters: Many regulated casino bonuses are only available in specific states (NJ, PA, MI, WV, etc.). Don’t assume a national offer applies where you live. (PokerNews.com)
• Read the fine print: check eligible games, wagering/playthrough requirements, max cashout from no‑deposit funds, expiry/claim window, ID verification rules, and bet-size caps. These conditions determine the real value of a no‑deposit bonus. (LegalSportsReport.com)
• Max cashout & wagering: Many no‑deposit freeplays/free spins have a low maximum withdrawable amount or require wagering (sometimes generous, sometimes strict). A $25 freeplay with 1× playthrough and $100 max cashout is far better than $100 free spins with a 30× requirement and $20 max cashout. (Insider-Gaming.com)
• Account verification & bonus expiry: Bonuses often require phone/email verification and must be claimed within days of registration — act quickly. (PokerNews.com)

Quick recommendation (practical)

• If you’re in a regulated casino state (NJ/PA/MI/WV): check BetMGM and Borgata first for the $20–$25 freeplays — reputable brands and straightforward redemption. (PokerNews.com)
• If you’re outside regulated states or want no‑risk sweepstakes play: try a reputable sweeps site (Rush/Chumba/Pulsz) that offers free/sweeps coins. Read conversion/withdrawal rules carefully. (LegalSportsReport.com)
