Decode vs Silver Oak pits a newer crypto-first casino against an older RTG site, and the biggest difference is how much each tells you. Silver Oak publishes its operator, an Anjouan license and detailed terms; Decode publishes almost none of that. Both are offshore, neither is licensed by a US state, and both carry offers via our links.
Silver Oak names Primrose Media Limited and an Anjouan license in its terms; Decode names neither, and third parties disagree.
Michigan's gaming board named Silver Oak on April 9, 2025; Decode isn't among the partner brands in the releases on record.
Silver Oak's own pages state 30x wagering in one place and 40x in another, with no max cashout on its welcome match.
Silver Oak charges 3%–10% on card deposits and caps withdrawals from $2,500 a week; Decode's caps are reported at $2,500 or $5,000.
Via our links: Decode $5,000 + 50 free spins; Silver Oak $2,500 + 50 free spins. New players, 21+ (18+ where allowed), terms apply.

Decode vs Silver Oak: the quick answer
If you want to read the rules before you deposit, Silver Oak Casino is the more transparent of the two: its terms name the operator, the license, the wagering, the fees and the withdrawal limits. If you want a bigger headline bonus and a wider game lobby, Decode Casino offers more, but almost everything about it comes from third-party reviewers rather than its own pages.
Neither is a low-risk choice. Both are offshore, neither is licensed or regulated by any US state, and both draw complaints about slow or disputed payouts. Silver Oak also has a Michigan cease-and-desist on its record.

License and operator: what each casino actually publishes
Silver Oak's terms and conditions (opens in a new tab) name Primrose Media Limited, registration number 15804, based in Mutsamudu on the Autonomous Island of Anjouan in the Union of Comoros, licensed under Anjouan's Computer Gaming Licensing Act 007 of 2005. No separate license number is shown. LCB disagrees, listing "no license" and mentioning Costa Rica.

A named Anjouan license is more than Decode offers, but it's not US oversight. Neither casino gives you a state regulator to complain to. Our guide to offshore vs state-licensed casinos explains the practical difference.

Silver Oak in Michigan, and Decode's complaint record
The Michigan Gaming Control Board's April 9, 2025 release (opens in a new tab) names Silver Oak among 13 unlicensed offshore sites told to stop serving Michigan residents within 14 days. The board describes such sites as illegal offshore operators. Michigan residents have state-licensed online casinos; see online casinos in Michigan.
Decode isn't among the partner brands in the Michigan releases on record. That isn't an endorsement; Michigan only licenses casinos under its own law, and Decode isn't one of them.

Decode vs Silver Oak welcome bonus and bonus codes
Silver Oak's new member offer (opens in a new tab) is a 100% match on each of your first ten deposits, worth up to $10,000, with codes SILVEROAK1 through SILVEROAK10. The page says 30x playthrough and 60x for blackjack and video poker, but the general terms say 40x on slots, keno, bingo and scratch cards and 60x on table games and video poker. No expiry is stated, and the site offer includes no free spins.
Decode's own site (opens in a new tab) advertises a $111 free chip and crypto bonuses without visible terms. Third-party reviewers list several codes: LCB shows EASY25CODE at 400% with 35x and a $25 minimum, DECODE111 at 111% up to $1,111 with 25x, and a 25% cashback at 20x; VegasSlotsOnline lists 500% plus 50 spins on Johnny Cash at 30x. LCB says bonuses are valid for 90 days.
Via our links the headlines differ again: Decode $5,000 + 50 free spins and Silver Oak $2,500 + 50 free spins. The terms shown at sign-up apply, so read them. Both offers are slot-focused: Silver Oak's terms exclude baccarat, craps, roulette, pai gow poker, sic bo, live dealer and progressives from bonus play, and table games are often excluded or weighted lower elsewhere. Codes change; see Decode bonus codes and Silver Oak bonus codes.
What each bonus costs to clear, per $100 deposited
Wagering × house edge gives the average cost of clearing a bonus. The table uses a 3.75% edge, matching RTG's Sweet 16 at 96.25% RTP as listed by third parties; your slot may differ.

Notice how the 30x vs 40x conflict at Silver Oak adds $75 to the average cost on the same $100. On Decode's 500% version, the average cost exceeds the $600 balance, so most players won't finish. Bigger percentage, bigger wagering. Our expected value of a bonus guide shows the full method.
Decode vs Silver Oak no deposit bonus codes
Silver Oak's no deposit page lists SILVER25 ($25), SILVER50 ($50) and FREESILVER ($100), at 30x (60x for blackjack and video poker) with a $100 max cashout; its terms put the cap at 1x the bonus with a $100 minimum. For Decode, LCB lists RTG50GRANDE for 50 no-deposit free spins on RTG's 777 slot, at 40x with a $200 max cashout and a $10 max bet, and Decode's own site advertises a $111 free chip.
A no-deposit chip still has to be wagered, and the cap limits what you keep. On SILVER25, $25 × 30 = $750 to wager, and at most $100 can come out. LCB members also report Decode no-deposit codes not being honored, so screenshot the terms before you play.
Deposits: card fees and crypto minimums
Silver Oak's banking page (opens in a new tab) lists Bitcoin, Litecoin and Ethereum from $30 to $100,000 with no fee, and Visa, Mastercard, Amex and Discover from $30 to $1,000 with a 3%–10% fee. A $500 card deposit could cost $15 to $50 before you play. Changelly runs $60 to $200.
LCB lists Decode deposits by Visa, Mastercard, Amex, Discover, Diners Club, Bitcoin, Bitcoin Cash, Ethereum, Litecoin, bank wire and check, from $5 by Lightning Bitcoin, $10 by Litecoin or Bitcoin Cash, and $25 otherwise. No card fee is reported. US banks often decline gambling transactions under merchant code 7995, which is why crypto is the main route; read card declines and how to buy Bitcoin for casinos.

Allow up to four weeks from request to receipt.
Decode's figures are thinner and conflict: LCB's listing shows $2,500 a week, while its review text and VegasSlotsOnline say $5,000. Crypto withdrawals are reported by Bitcoin only. Before a big deposit, read Silver Oak withdrawals and Decode withdrawals.
RTG slots at both, but Decode's lobby is wider
Silver Oak's mobile page names RealTime Gaming and lists titles such as Magic Mushroom, 777, T-Rex II, Storm Lords, Cash Bandits 3, Vegas Lux, 5 Wishes and Fortunate Zeus. LCB counts 356 slots and adds Spinlogic; no live dealer games are reported.
Decode's site meta promises 300+ RTG slots and Star Trek-branded games without naming them. LCB lists about 33 studios, including Rival, Arrows Edge, Belatra, Mascot and BetSoft, but notes that US players can't access several, such as Pragmatic Play, Habanero and Yggdrasil. VegasSlotsOnline counts about 2,500 games, names Johnny Cash and Fat Ca$h, and reports no live dealer. Counts vary widely by source, so check the casino's lobby for a specific title.

Responsible gambling tools at Decode and Silver Oak
Silver Oak's terms list deposit limits, cool-off periods and self-exclusion through live chat, processed immediately, and its responsible gambling page adds temporary self-bans and permanent closure, with links to Gamblers Anonymous, the National Council on Problem Gambling and Gambling Therapy. Decode's help page didn't render, so its tools aren't published on record; ask support in writing.
Whatever casino you use, treat play as paid entertainment and set a budget first. The National Problem Gambling Helpline is 1-800-MY-RESET (1-800-697-3738), by call, text or chat through ncpgambling.org (opens in a new tab). Our Silver Oak responsible gambling page covers its tools in detail.

Do Decode and Silver Oak have the same games?
They overlap on RealTime Gaming slots but differ beyond that. Silver Oak's site names RTG titles like Magic Mushroom, T-Rex II and Cash Bandits 3, while Decode advertises 300+ RTG slots and Star Trek games and third parties report dozens of other studios. Neither reports live dealer games. Our RTG software guide explains the platform both use.

Both take Bitcoin and pay out in Bitcoin. Silver Oak publishes $30 to $100,000 crypto deposits with no fee, but Bitcoin withdrawals of $50 to $2,500 with fees up to $40 and 7–10 days. Decode is reported to take Lightning Bitcoin from $5 and to pay Bitcoin within 48 hours, minimum $100. Confirm in the cashier. See best Bitcoin casinos.

Decode's lowest reported deposit is $5 by Lightning Bitcoin, while Silver Oak's banking page starts every method at $30.

Silver Oak's terms ask for a government photo ID, the front and back of any card used in the last three months, a selfie holding your ID and a utility bill dated within three months. Withdrawals stay blocked until verification is complete, and no turnaround time is stated. Decode, per a third-party reviewer, wants similar documents and reports checks in 0–2 days. Send clear, uncropped files before your first cashout so nothing stalls. Our Silver Oak verification page and account verification guide walk through the process.
What no deposit codes do Silver Oak and Decode offer?
Silver Oak lists SILVER25 for $25, SILVER50 for $50 and FREESILVER for $100, each at 30x wagering (60x for blackjack and video poker) with a $100 max cashout. Its general terms put the cap at 1x the bonus with a $100 minimum, so read both. On SILVER25 you'd wager $25 × 30 = $750, and at most $100 comes out. Decode's comparable reported code is RTG50GRANDE, 50 spins at 40x with a $200 cap. Codes change, so check the cashier. See no deposit bonuses and Decode's no deposit bonus.
Can Michigan players sign up at Silver Oak or Decode?

Decode isn't among the partner brands in the Michigan releases on record, but it holds no Michigan license either. Michigan residents can choose from state-licensed online casinos instead.
