Mamba Limited launched Spinsly Posters on Sept. 22, offering a single-currency casino site restricted to California and New York. The Isle of Man operator’s new poster-branded site is available in the two states where its conventional dual-currency Spinsly service does not operate.
The launch forms part of a small group of sites using a model that packages one cash-redeemable coin with a randomized digital item, such as a poster. That coin is the player’s only account balance: it can be wagered on casino games and redeemed at $1 per coin once minimum-balance and playthrough rules are met.
RG.org reported that poster sites, including Spinsly Posters, require players to accumulate 100 coins before redemption. The sites retain a handwritten mail-in entry route and restrict access to people aged 18 or older. Standard coin packages generally cost about $2 per coin, while discounted welcome offers price them at 40 cents to 50 cents each.
New York users of Spinsly Posters face a $5,000 cap on individual spins. California players do not face that stated per-spin restriction.
The model differs from the usual sweepstakes-casino structure, which uses Gold Coins with no cash value for entertainment play alongside Sweeps Coins that may be redeemed for prizes. KPMG has said Sweeps Coins are generally made available free through purchase bonuses, log-in rewards, promotions and mail-in requests, rather than sold directly.
Single-currency sites instead remove the entertainment currency and classify the purchased digital item as a collectible, a category not named in the relevant restrictions. Mamba also launched Amazon Jackpots Posters earlier in September, likewise for California and New York only.
The two states have recently curtailed dual-currency casino-style sweepstakes. California’s AB 831 took effect Jan. 1 after being signed in October 2025, removing the promotional-game exemption for such offerings. New York Governor Kathy Hochul signed S5935A in December 2025, with penalties of $10,000 to $100,000 per violation.
New York’s attorney general had already taken action against the earlier model. In June 2025, Attorney General Letitia James said 26 online platforms identified as offering casino games or sports betting with cash-redeemable virtual sweepstakes coins agreed to stop selling those coins in the state after receiving cease-and-desist letters.
As of late September, however, no state regulator or attorney general had issued a cease-and-desist letter, filed a lawsuit or published guidance naming Spinsly Posters or the other listed single-currency brands. Four such brands were live in California and New York, operated by three Isle of Man companies that also run conventional dual-currency casinos.
