Stackr Casino sign up bonus: 500k GC + 5 SC + 150% extra
The first thing that I look for when I sign up to a new online sweepstakes casino in the US is the welcome bonus. As these types of gaming sites legally have to facilitate free play, most brand’s offer an initial no purchase bonus, and Stackr is no exception.
Upon registration, I was given 500,000 Gold Coins (GC) and 5 Sweepstakes Coins (SC), which is a fairly standard no purchase welcome bonus for a social casino in my experience. While no purchase is required to play here, I was quickly made aware of an additional welcome offer to incentivize a first Gold Coin purchase.
As is commonplace at many other sweepstakes and social casinos online in 2025, you can get 150% extra coins on a special first GC purchase package. However, as I alluded to above, this part of the welcome package is totally optional.

Stackr review - Usability, look, and feel
My first impressions of this sweepstakes casino website were that it was fairly well designed and looked clean and professional enough. In terms of navigation the layout follows the standard social gaming site model and is easy enough to navigate, even if it lacks special or unique features that I often look for that make a site stand out.
The branding and color scheme is fairly ordinary with dark blue and black background and golden branding. Before signing up, I was unable to get full access to the site, as all you have is a stripped back version of the homepage.
I therefore had to register before I could see the website in all its glory; you have the game lobby in the middle, a menu bar to the left and your coins balance and profile at the top. Again, a pretty run-of-the-mill online sweepstakes casino that’s not bad, but nothing to write home about.
Mobile site - A browser-based platform
Like many other online sweepstakes casinos in the US in 2025, this brand hasn’t developed an official app. Mobile gameplay is therefore facilitated via the mobile-optimized website, which does an able job.
The mobile website is pretty neat in terms of layout and is easy enough to scroll through and navigate. It is essentially a carbon copy of the desktop website, such with the sidebar tucked away into a popup button.
When using my iOS devices, I found that Safari was the best browser to use (no surprise there). Meanwhile, for Android users, I would recommend Chrome or Firefox.

Payments - Instant purchases but potentially long redemptions
I hope I’ve already made it clear throughout my Stackr review that we’re dealing with a sweepstakes casino and not a traditional online casino here. For those of you who are uninitiated, you cannot deposit and withdraw real money funds into your account.
At sweepstakes casinos, you play using virtual currencies - GCs and SCs - and you can play for free. However, you can optionally purchase GCs on this site in bundles using your credit or debit card (Visa and Mastercard are accepted).
The on-site purchase process is pretty straightforward and in my experience transactions were always processed instantly. There are promotional GC bundles that come with free SCs as a bonus.
Prize redemptions
To make your SCs redeemable for real prizes, you have to play through them at least once on games. You then need at least 50 SC for gift cards or 100 SC for real money prizes, and the redemption rate is the standard 1 SC = $1.00.
In total, the processing time can take up to 10 days, or more if your prize exceeds $500, which is a bit longer than most other social casinos I’ve redeemed from. Additionally, I was only able to have one active redemption be processed every 72 hours - most sweepstakes casinos process one redemption every 24 hours.
Customer support - Available 24/7
The customer service team at this sweepstakes casino is, to an extent, available 24/7. Before you reach out to them, I recommend making use of the help center/ FAQ section, which is sufficient for basic troubleshooting.
Here is my Stackr review for each customer service channel:
- Live chat:
For me, this was the quickest and easiest way to get fast answers and have back-and-forth communication. However, they will on occasion try to direct you to the FAQs which can be frustrating at times.
- Email:
A similar level of service to the live chat, only it’s not manned 24/7, and response times tend to be a little bit slower, even during working hours.
- Social media:
The brand is pretty active on Facebook, Instagram, and X (Twitter), and you can join a Discord channel.

License & Security - Everything is above board
Firstly, I’ll address your safety and security here. The site is properly encrypted and all of my financial transactions were safe. No state-of-the-art software is used here, but you should be safe while using this site, I’m pretty confident of that.
Sweepstakes casinos are not gambling sites, and therefore don’t need to be licensed and regulated in every state in the same way that traditional online casinos do. Instead, they need to have a set of T&Cs and Sweeps Rules that adhere to US sweepstakes laws and social gaming regulations. The main thing to know is that you have to be over 18 to play in most locations.
This brand has all of the required documents, but there are a lot of Prohibited states. I usually find that sweepstakes casinos have anywhere between one and 10 prohibited states, but curiously Stackr is unavailable in 28 states:
Vip & rewards program at Stackr Casino
At this sweepstakes casino, there is a classic loyalty/VIP program with seven levels, Bronze through to Ruby. I found it easy enough to get started, as part of the no deposit signup bonus rewards you with an instant upgrade to the Bronze tier.
Although a bit of a gimmick, it at least makes you aware that the VIP there is there and accessible from the very beginning. The VIP perks here include:
- Daily coin boosts
- Weekly rakeback
- Annual bonuses
Compared to other online sweepstakes casinos, the games lobby at Stackr is fairly modest, with just over 150 games. That being said, the slots have been provided by recognized software developers, including Hacksaw Gaming and Novomatic.
Some games that I was previously familiar with include Wanted Dead or a Wild and Book of Ra Deluxe Slot. However, if you’re looking for table games or other casino-style games, this isn’t the place.
In this part of my Stackr review, I’ll take a look at how the virtual currency system works. Firstly, there are two types of coins that you can use to play games:
How to get coins
To start with you get 500,000 GC + 5 SC free as a welcome offer, after which you have the option to purchase extra GCs. However, you cannot buy SCs at any point and instead can only collect them through these promotions:
At the end of the day, this is a pretty ordinary online social casino with two virtual currencies and an average selection of around 150 games. You can play for fun with Gold Coins (GC) or for the chance to win real prizes at Sweepstakes Coins (SC). As a final reminder, the welcome offer is 500k GC + 5 SC.
