Here are U.S.-accessible online casinos known for low minimum deposits (summary of typical minimums, states where they operate, and a note on sweepstakes/social options that allow even lower or no deposit). Minimums and availability vary by state and payment method — check the casino’s cashier/terms for your state before registering.

Real‑money regulated casinos (typical minimums)

• DraftKings Casino — commonly accepts a $5 minimum deposit in states where its casino is live (examples: MI, NJ, PA, WV). (gambling.com)
• FanDuel Casino — frequently offers $5–$10 minimum deposits depending on payment method and state (operates in multiple regulated states). (gamingtoday.com)
• Caesars / Caesars Palace Online Casino — often has $5–$10 minimums (state/payment dependent). (rotowire.com)
• BetMGM Casino — industry-standard $10 minimum in most markets (NJ, PA, MI, WV in many guides). (gambling.com)
• BetRivers — commonly $10 minimum; available in several regulated states (MI, NJ, PA, WV). (gambling.com)
• Borgata / bet365 — many guides list $10 minimums for these NJ/PA operators. (agamble.com)
• Ignition and some offshore/crypto-friendly sites — typically higher than $5 (Ignition often cited around $20), but appear on “low-deposit” lists because they accept relatively small amounts compared with many offshore alternatives. Availability and legality differ by state — be careful. (globenewswire.com)

Sweepstakes / social casinos (very low or no real‑money deposit to play)

• Chumba Casino, LuckyLand Slots, WOW Vegas, Jumbo88, Rolla and other sweepstakes/social models let U.S. players play without an initial real‑money deposit (they use “Gold Coins” + “Sweeps Coins” and have ways to redeem winnings for cash under sweepstakes rules). These are legal in most states and allow much smaller purchases (often from a few dollars) or free play; however, they are not the same as state‑regulated real‑money casinos and have different withdrawal rules.

Quick tips before you deposit

• Minimum deposit vs. bonus requirement: a casino may allow a $5 deposit but require $10+ to unlock a welcome bonus — read the bonus terms. (gambling.com)
• Payment-method limits vary: PayPal, Venmo, Apple Pay, cards, and bank transfers can have different minimums; sometimes e‑wallets let you deposit less. (agamble.com)
• State licensing matters: availability and allowed deposit methods depend on the state (NJ, PA, MI, WV, CT, etc.). Only register where the operator is licensed. (gambling.com)
• If you want the absolute lowest outlay, sweepstakes/social casinos let you try games with tiny purchases or free options — but read the sweepstakes redemption rules carefully. (TalkSport.com)
