Who Sunflower is

The Crown Coins Casino Terms of Service (version 4.1, last updated 08/09/2026) define "we, us, our, Sunflower" as "Sunflower Limited of PO Box 5114, Fredericksburg, VA 22403-5514 and Stiarsia Ltd. of 1/95 Agias Fylaxeos 3087 Limassol, Cyprus". They list Sunflower Technology Inc., at the same Fredericksburg PO box, as an Affiliated Entity.

The site footer says Crown Coins Casino "is operated by Sunflower Group (Sunflower Ltd., Stiarsia Limited, and Sunflower Technology Inc.)" and that the sweepstakes promotions and prizes are operated, and all payments processed, by Sunflower Group. The copyright line reads "Copyright © 2025 Sunflower Limited".

The Cyprus Department of Registrar of Companies lists STIARSIA LTD, HE 468809, as a registered company [1]. The terms do not say where Sunflower Limited or Sunflower Technology Inc. are incorporated, and both give only a Virginia PO box. We did not find a registry record for either on this run, so their jurisdiction stays open.

How we know who runs it

  • The Crown Coins terms and footer name Sunflower Limited, Stiarsia Ltd and Sunflower Technology Inc.
  • Maryland addressed its June 2025 letter to "Sunflower Limited d/b/a Crown Coins Casino" at PO Box 5114 [2].
  • Illinois sent its February 2026 Crown Coins letter to the same PO box and emailed an info address on a Sunflower Ltd domain as well as Crown Coins support [3].
  • Stiarsia Ltd's registry number HE 468809 matches the number our review gives [1].

Crown Coins Casino and our review

Crown Coins Casino scores 8.1/10 in our review. Crown Coins uses its own name for Gold Coins: Crown Coins (CC) are the play-for-fun currency, and Sweeps Coins are the prize currency. The welcome offer is 100,000 Crown Coins plus 2 Sweeps Coins. The minimum redemption is 50 SC. Players must be 18 or older.

Our review notes that since July 2026 Indiana players use SC Tickets, and wins go to a cash balance that can be redeemed from $50.

Where Crown Coins is available

The terms define the Excluded Jurisdiction as Idaho, Louisiana, Michigan, Montana, Nevada and Washington, plus US territories and anywhere outside the US. The summary at the top of the same terms also lists California. Residents of Connecticut, New Jersey and New York can't use the platform when they are outside their home state.

Our review adds that Connecticut, Maine, New Jersey and Tennessee get Crown Coins play only, with no Sweeps Coins.

Oklahoma: the terms we read do not mention Oklahoma. SB 1589 takes effect on 1 Nov 2026 [5]. We have not seen a Crown Coins notice about Oklahoma, so check the site before you play there.

Regulatory history

  • Maryland: on 3 Jun 2025 the Lottery and Gaming Control Agency wrote to Sunflower Limited d/b/a Crown Coins Casino, by mail and email, saying it was offering online gaming in Maryland without legal authority and asking it to stop within 10 days [2].
  • Tennessee: the Attorney General's 29 Dec 2025 release lists Crown Coins Casino among sites that received cease-and-desist letters and said they would comply [4]. Our review lists Tennessee as Crown Coins play only.
  • Illinois: the Gaming Board's letter is dated 4 Feb 2026. Staff said they saw play on Crown Coins on 9 Jan 2026 [3].

Where the sources disagree

  • California. The terms summary excludes California, but the Excluded Jurisdiction definition and our review's state list do not. Our review mentions California only for payment methods. Treat California as excluded until Crown Coins makes the two lists match.
  • Maryland and Illinois. Neither state is in the terms' Excluded Jurisdiction list or our review's restricted list, even though both regulators told Sunflower to stop.
  • Jurisdiction of Sunflower Limited. The operator gives a US PO box and no registry number, and we have not found a public record that settles where it is incorporated.
