Do bonus codes expire? Yes, most do. A casino can retire or replace a code at any time, seasonal codes end on a set date, and once you redeem one the bonus it gives has its own deadline for finishing wagering. Two clocks are running, and missing either one can cost you the offer.
Bonus codes expire in two ways: the code stops being accepted, or the claimed bonus runs out of time.
SlotoCash's general terms give 90 days from redemption to use a bonus; other partners don't publish one figure.
Code lists on third-party and unofficial mirror sites are often out of date, so check the casino's own promotions page.
Never treat a deadline as a reason to deposit more than you planned.

Do bonus codes expire? The short answer
Yes. Almost every casino bonus code is temporary, even the ones that seem to be around for years. Casinos rotate codes with the calendar, swap welcome codes when they redesign an offer, and retire codes that are being shared too widely.
There's a second deadline people often miss: after you redeem a code, the bonus itself has a time limit for meeting the wagering requirement. If that clock runs out, the bonus and its winnings are removed. This page in our casino questions hub explains both deadlines and how to check them.

The first two decide whether you get the bonus at all. The last two decide whether you keep what it produces. Our bonus expiry guide covers the validity clock in more detail.
How long different bonus codes usually last
Code lifespans follow the purpose of the code. Welcome codes tend to last longest, while event and holiday codes are the shortest-lived.
Welcome codes run until the casino changes its new-player package. SlotoCash's published series uses SLOTO1MATCH to SLOTO5MATCH, and Silver Oak's uses SILVEROAK1 to SILVEROAK10, according to each casino's site.
Rotating reload codes change with the casino's promotions calendar. SlotoCash's promotions page (opens in a new tab) lists codes such as SUPERFRIDAY and SLOTONOLIMITS, each with its own minimum deposit and wagering.
Anniversary and seasonal codes are tied to an event. SlotoCash's SLOTOBDAY19 marks its 19 years online, and Decode's seasonal codes change through the year, so check its cashier for the current one and its end date.
No-deposit codes are often limited and closely watched. Silver Oak's no-deposit page lists SILVER25, SILVER50 and FREESILVER.
Personal codes, like birthday or VIP chips, usually have the shortest windows.

How much time a bonus really needs: a dollar example
A 90-day window sounds generous until you work out the betting it covers. SlotoCash's promotions page lists SUPERCASTLE as a 200% match with a $100 minimum and 30x wagering.

On average, the house edge over $9,000 of bets is larger than the $300 starting balance, so most players won't finish with money left. Some will, because results vary. The deadline doesn't change the math; it only limits how long you have to play it out. The expected value of a bonus guide applies this to any offer.
Why a bonus code fails when it hasn't expired
A rejected code isn't always an expired one. These are the other common reasons:
Wrong timing. At SlotoCash, coupons must be redeemed before the deposit or right after it, before any bet.
Wrong order. SlotoCash's welcome codes must follow deposits one to five in sequence.
A withdrawal is pending. SlotoCash's terms bar bonuses while a withdrawal is waiting.
Deposit too small or wrong method. SlotoCash's BLOCKFALL-1 is a crypto deposit bonus with a $25 minimum.
Already used or not eligible. Welcome and no-deposit codes are usually once per player.
Location. Decode is reported to refuse players from Maryland, New Jersey, New York and Washington.
If a code fails after you've deposited, contact support before you place any bet, because playing first can make it impossible to add the bonus later. See how to claim a casino bonus.
How to check whether a bonus code still works
Open the casino's own promotions or cashier page rather than a code list elsewhere.
Find the code's terms: minimum deposit, wagering multiple, max cashout, eligible games and any end date.
Check the bonus validity period in the general bonus terms, not only the offer page.
Confirm when to enter the code: before the deposit, during it or right after.
If anything isn't stated, ask live chat and save the transcript.
Enter the code, then check your balance shows the bonus before you place a bet.
Found an expired bonus code? What to do
If the casino won't accept a code, it's gone; there's usually no way to revive it. Look for the replacement on the casino's own promotions page, or play without a bonus. Our pages on expired bonus codes and bonus codes that work explain how to tell current codes from stale ones.
Don't let an end date push you into a deposit you hadn't planned. A code with a deadline is still a bonus with wagering, a max bet and the house edge working against you.
Bonus codes at offshore casinos: the US context
The three partners here are offshore, and none is licensed or regulated by a US state. If a code is refused or a bonus expires earlier than you expected, there's no state regulator to complain to, and the casino's current terms decide. Silver Oak names its license (Primrose Media Limited, Anjouan); third parties report Curaçao or no license for SlotoCash and Decode.
These are the offers we promote. Each casino is offshore and not licensed by any US state, so check your state's law first. New players only, 21+ (18+ where allowed), terms apply. Codes change, so use the code and terms shown at sign-up.
SlotoCash Casino: $6,000 Welcome Bonus + 60 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). The SlotoCash bonus terms (opens in a new tab) say 25x deposit plus bonus, a $20 minimum, no max cashout and a $10 max bet, with 90 days' validity in its general terms; its site advertises a different $7,777 package.
Decode Casino: $5,000 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Third-party listings report EASY25CODE at 35x bonus plus deposit, a $25 minimum, no max cashout and 90 days' validity; Decode's own terms weren't readable, so confirm at sign-up.
Silver Oak Casino: $2,500 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Its welcome offer page (opens in a new tab) advertises a different $10,000 package using SILVEROAK1 to SILVEROAK10, with 30x on the offer page but 40x in its terms; no expiry is published.

Frequently asked questions
How long do casino bonus codes last?
There's no standard length; it depends on the code's purpose. Welcome codes can run for months until the casino changes its package, while seasonal and event codes often last days or weeks. Once redeemed, the bonus has its own validity period, which SlotoCash's general terms set at 90 days. Check the casino's own promotions page. See our bonus codes guide.
Can I use an expired bonus code?
No, once a code has expired the cashier won't accept it, and support usually can't apply it manually. Look for the current replacement on the casino's own promotions page instead. Be wary of sites that still list old codes, especially unofficial mirror sites. Our page on expired bonus codes explains how to spot stale lists.
What happens if my bonus expires before I finish wagering?
The bonus and any winnings tied to it are usually removed when the validity period ends. Only cash that the terms treat as yours, if any, remains. Check the deadline before you claim, and work out whether the wagering is realistic in that time. Our page on why a bonus was removed covers this and other causes.
Why is my bonus code not working?
Expiry is one reason, but timing, order, deposit size and payment method are just as common. At SlotoCash, codes must be entered before the deposit or right after it, before any bet, and welcome codes must be used in order. A pending withdrawal can also block a bonus. Contact support before you play. See how to claim a casino bonus.
Do no deposit bonus codes expire faster?
Often, yes. No-deposit codes are closely watched because they cost the casino money without a deposit, so they're frequently retired or limited to one use per player. They also carry low cashout caps; Silver Oak lists $100 on its free chip codes. Read the terms before you claim. Our no deposit bonus guide has more detail.
Do comp points and birthday bonuses expire?
Yes, they usually do. Silver Oak's site says comp points expire after 12 months and birthday chips are valid for seven days. SlotoCash converts 100 comp points to $1, according to its promotions page. Use or redeem rewards before the deadline if you plan to play anyway. See our pages on comp points and the birthday bonus.
Are bonus codes from third-party sites reliable?
Only as a starting point. Review sites record codes on the date they checked, and many lists aren't updated when casinos change offers, so codes may have ended. Unofficial mirror sites are less reliable still. Always confirm the code and its terms on the casino's own promotions page. Our how to read casino terms guide shows what to look for.
Do SlotoCash reload and welcome codes run out?
Yes, SlotoCash codes change with its promotions calendar, and a redeemed bonus has 90 days under its general terms. The welcome codes SLOTO1MATCH to SLOTO5MATCH run until the casino changes its package, while rotating reloads such as SUPERFRIDAY or SLOTONOLIMITS come and go, and SLOTOBDAY19 is tied to its anniversary. The welcome bonus terms themselves don’t state a separate expiry, so the 90-day rule is the one to plan around. Check the promotions page on the day you deposit. See SlotoCash bonus codes and the SlotoCash welcome bonus page.
Do Decode Casino bonus codes expire?
Yes, third-party listings report a 90-day validity on Decode bonuses, and its seasonal codes change through the year; one listed seasonal code ended on October 31, 2026. EASY25CODE (35x bonus plus deposit, $25 minimum) and DECODE111 (25x) are the codes reviewers report most often, but Decode’s own terms couldn’t be read, so confirm the code and its end date in the cashier before depositing. Decode is also reported to refuse Maryland, New Jersey, New York and Washington. See Decode bonus codes and is Decode Casino legit.
Is Miami Club’s MIFREE20 free bonus code time-limited?
MIFREE20 is a monthly offer, $20 free each month according to Miami Club’s promotions, so treat each month’s claim as its own window. Its deposit bonuses work differently: the terms say they don’t expire and stay active until wagering is met, at 20x deposit plus bonus. Free balances carry a separate risk, because accounts that never deposit lose their balance after 60 days of inactivity. Miami Club’s terms (section 1.6) list the US as prohibited while its affiliate program confirms US players are accepted, so confirm at sign-up. See Miami Club bonus codes and its no deposit bonus page.
Is there an expiry date on Planet 7 bonus codes?
Planet 7’s codes do change, but no expiry period has been published for them in the sources we checked. Third-party reviews report WELCOME200 as a 200% match at 30x bonus plus deposit on slots with a $1,000 max cashout, and a $25 free chip code with a $100 cap, while other code lists come from unofficial mirror sites that shouldn’t be trusted. Because the official terms couldn’t be verified, ask live chat for the end date and validity before you deposit. See Planet 7 bonus codes and Planet 7 no deposit bonus.
Do Slot Madness bonus codes expire?
They can change at any time, and Slot Madness hasn’t published an expiry period that we could confirm. Third-party reviews report MAD275, a 275% match with a $30 minimum, 30x on slots and no max cashout, and a PROGRESSIVE100 code giving 100% for progressive jackpot games with a 10x max cashout and deposits of $30 to $1,000. Sources describe the welcome match differently, so check the cashier on the day. Michigan’s regulator named Slot Madness in August 2025. See Slot Madness bonus codes and the Slot Madness welcome bonus.
Does a casino balance or bonus expire if I stop logging in?
Yes, dormant-account rules can remove a balance even after a bonus has cleared. SlotoCash’s terms void balances after 12 consecutive months without a login, though management may restore them. Miami Club marks accounts inactive after 12 months and removes the real-money balance, reinstatable on request, and deposit-free accounts lose their balance after 60 days. Silver Oak treats accounts as inactive after two years and may delete them after an email notice. Withdraw what you want to keep. Our guide to dormant casino accounts and closing a casino account explain the options.
When do Silver Oak bonus codes and rewards expire?
Silver Oak doesn’t publish an expiry for its welcome codes SILVEROAK1 to SILVEROAK10, but its other rewards do run out: the casino says birthday chips are valid for seven days and comp points expire after 12 months. No-deposit codes such as SILVER25, SILVER50 and FREESILVER carry a $100 max cashout on its no-deposit page. Wagering also conflicts, 30x on the offer page against 40x in the terms, so read both before you claim. See Silver Oak bonus codes and the Silver Oak no deposit bonus page.
Do sweepstakes casino promo codes expire?
Yes, sweepstakes promo codes change often, and some welcome offers only exist through a specific affiliate code. A third-party review says Stake.us’s welcome package depends on the code used, and McLuck’s no-purchase offer of 7,500 GC plus 2.5 SC is reported with an affiliate code. High 5 Casino’s blog lists a free sign-up bonus that one tracker marks as not currently active. Sweepstakes codes also stop working entirely in states that ban the model, such as New York and California. See Stake.us promo codes and our sweepstakes casino bans page.
