Michigan warning: Michigan’s regulator lists Supernova among operators issued cease-and-desist letters. Offshore acceptance does not establish Michigan authorization. Regulator list

Supernova has a specific cards promotion rather than relying on a slot welcome offer that happens to mention blackjack elsewhere. That makes its bonus structure relevant to a blackjack-focused review. The main reservation is regulatory transparency: its website’s licensing statement and LCB’s current classification disagree. We have not verified an active licence with a regulator.

US access and licensing

LCB lists Supernova as accepting US players. The operator’s restricted-territory list expressly includes Michigan, alongside several countries. The evidence supports describing it as an offshore casino serving some US customers, with Michigan excluded. It does not establish access in every other state or permission under local law. LCB review, operator terms

The official promotions page says the casino is licensed and operated in Curaçao. LCB, however, lists “No License” among its disadvantages. These claims should remain visible as a conflict, rather than being resolved by repeating the operator’s footer. LCB also reported that Supernova and seven related brands completed probation in November 2023. That historical reinstatement is separate from licence verification and is not a guarantee about future withdrawals. Official promotions, LCB review, LCB’s 2023 update

What the blackjack-related offer covers

The published cards offer is a 120% match. It applies to the first two deposits, requires at least $25, and is described as cards-only with 45x playthrough and no promotional maximum cashout. The same page advertises a separate 300% slots match. Those two offers should not be combined into a single headline or described as interchangeable. Promotion terms

The general terms explicitly place blackjack within the card-games category and state that card-match wagering applies to the bonus amount, rather than deposit plus bonus. Promotional funds are normally non-withdrawable and are deducted at withdrawal. Baccarat, craps, Pai Gow Poker, Pontoon 21, Sic Bo and War are generally excluded. We found no clear live-dealer eligibility statement or published maximum-bet figure for this cards offer; neither should be assumed. General bonus terms

Banking and account restrictions

Supernova’s banking page lists cards and additional payment options that vary by location. It also requires a telephone verification after the first deposit and warns that incomplete verification can affect deposits, promotions and withdrawals. The same page describes deposit limits available through an account manager. These are published procedures, not a tested account experience. Banking information

The FAQ describes several withdrawal stages: document approval, casino processing and subsequent payment delivery. Its stated timelines can therefore add up to considerably more than a single processing window. It also says only one account is allowed per household, address, computer and IP address. Official FAQ

Editorial assessment

Supernova meets the narrower research test of having a publicly documented blackjack-related cards bonus and evidence of some US acceptance. The Michigan exclusion, noncashable bonus, uncertain live-dealer eligibility and licensing discrepancy remain material limitations. Its welcome percentage alone does not describe the cost or risk of the offer, and no payout-speed claim should be presented as independently verified.

Recorded software is not confirmation that a specific live blackjack table is available to you or eligible for a bonus. Table rules, operator restrictions and local authorisation still need checking.
