In my Stackr review, I’ll take you through my experience with this online sweepstakes casino so that you can decide if it’s for you. This is a browser-only platform with a modest selection of around 150 casino-style games.
As a new account holder, you can grab a welcome bonus consisting of 500,000 Gold Coins (GC) and 5 Sweepstakes Coins (SC). Additionally, your VIP status is instantly upgraded when you sign up and you can claim a free coins reload every five minutes whilst you play.

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.
| Welcome offers | What you get |
|---|---|
| No deposit signup bonus: | 500k GC + 5 SC |
| First-purchase promotion: | 150% extra coins |
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.
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.
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.
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.
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.

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:
| Alabama | Louisiana | New Hampshire | South Carolina |
| Alaska | Massachusetts | New Mexico | Tennessee |
| Arkansas | Michigan | New York | Texas |
| Georgia | Mississippi | North Dakota | Utah |
| Idaho | Missouri | Ohio | Vermont |
| Iowa | Nebraska | Oklahoma, | West Virginia |
| Kentucky | Nevada | Pennsylvania | Washington |
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:

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.
