Mystery box sites like Packz.io, BigBux.io and Card Crush are getting real popular these days. So, we figured we’d piece together an expert guide on how these unboxing sites work, and which ones we reckon are best.
Right here, right now, we’ll walk you through what mystery boxes are and how they work. Followed, of course, by our pro steps on how to sign up with a trustworthy site that offers them and start cracking open a few digital crates of your own. Without any further ado, then, let’s get to it.
What is a mystery box, exactly? Well, for you folks who haven’t stumbled across these before, mystery boxes are exactly what they say on the tin (or box, in this case) - they’re boxes with mysterious or unknown prizes inside.
In recent years, mystery box sites like Packz.io, BigBux.io and Card Crush have surfaced offering box-based reward systems where players can purchase mystery boxes containing such randomized goodies as online casino bonuses, Mystery Coins, collectable cards, real world merch, and sometimes even cryptocurrencies and NFTs.
Naturally, there are all sorts of different mystery box brands out there, and each one puts its own spin on the genre itself, and the types of wrapped up prizes for the taking, as you’ll see for yourself when we get to our reviews of the best mystery box sites currently on the market later in today’s guide.
That said, here’s a run through some of key things most modern mystery box brands have in common:
While mystery boxes admittedly lack the strategic allure of real money skill games, poker, or other online gaming favorites, we’re huge fans of their all-out simplicity.
And in our many years of gaming, we’ve found that not only is the rewards system used by the best mystery box websites super straightforward to wrap your head around, but you can typically sign up, grab a bonus and start purchasing boxes in minutes with these sites, too.
To grab a slice of the action for yourself, just follow these steps:
Click our banner links here to reach the best mystery box site for your own personal tastes.
Hit the “Sign Up” or “Register” button - usually located in the top right.
Enter your information and follow the on screen prompts.
Purchase your first mystery box - some sites might offer a welcome bonus or discount on your first purchase, while others won’t.
Open your box to reveal its contents - which, crucially, will always be completely randomized.
All sounds simple enough, eh? So next, let’s review some of the best mystery box websites on the market.
Sites specializing entirely in mystery boxes are admittedly a bit limited at the moment, as much like parimutuel games and other newly launched niches of igaming, the concept just hasn’t been around for all that long yet.
Having said that, there are three mystery box sites that our experts reckon stand head and shoulders above any others we’ve seen lately. And they are Packz.io, BigBux.io and Card Crush. Here’s how the three compare, followed by a mini review of each:
| Mystery box brand | Types of mystery box prizes available | Latest welcome reward |
| Packz.io | Physical, collectable cards - including Pokemon cards, as well as NBA, NFL, MLB and international league sports cards. | Purchase your first Pack “sweat-free” up to $100. |
| BigBux.io | Cars, clothes, watches, tech gadgets and other luxury goods. | Get “3 free boxes” on signup. |
| Card Crush | Mystery Coins and Cards. | Get 66% off your first Mystery Box. |
In this section, we take a closer look at what makes each of our favorite mystery box brands tick.
Packz.io is a mystery box site which, instead of selling traditional mystery boxes, offers “Packs” concealing popular, IRL collectable cards. And right now, it also offers what we think is one of the market’s best bonuses. How does the offer work? Well, with no promo code requirement, you can purchase your first “Pack” sweat-free up to a maximum of $100, and if the card inside is valued at less than what you paid upfront to crack your Pack open, the operator will buy it back from you for 100% of its original price.
The card Packs up for grabs here, which are split into various popular categories, such as “Sports” and “Pokémon”, start out at $25 and go up to $2,000+. All Packs display the odds of landing specific cards, too. Meaning the site is also great for transparency.
BigBux.io works a bit differently. Here, you sign up, fund your account, then purchase mystery boxes containing luxury items and tech gadgets in what BigBux likes to call a “gamified shopping” environment. New users can currently open three free boxes, although the T&Cs and limitations of this offer aren’t very clearly defined at the time of writing.
What we can tell you is that the site supports a ton of trusted payment methods, like MasterCard and Apple Pay, and has a solid customer support offering. What really wowed us here, mind, was its huge selection of different randomized prizes, which range from high-end cars and motorcycles, to designer bags and clothing. Each mystery box has a pre-stated value and comes with its own “product odds” powered by a provably fair algorithm, too - which we think is just ace.
Card Crush is a multipurpose mystery box brand. And we like how gaming-oriented it is when compared against the other mystery box sites mentioned above. Here, you can play classic casino-style games using “Mystery Coins” - which, you guessed it, can be collected by cracking open purchasable, randomized mystery boxes.
But that ain’t all the brand offers. In addition to Mystery Coins, Card Crush’s on-site boxes contain collectable, digital cards categorized into “Common”, “Rare”, “Epic” and “Legendary” groups. And these trading cards can be “Powered Up”, or used to compete in “Battles” with other site users.
We also like the fact that Card Crush offers several fast access responsible play tools, including self exclusion and spending limits. As, let’s face it, responsible play is as important as ever with mystery box sites. It’s vital not to get too carried away.
As we’ve seen, top Mystery box sites come in many shapes and sizes. But generally, they all have one important thing in common - they offer purchasable boxes which contain completely randomized prizes. And opening them up to see what’s inside is a hoot.
The best brands currently out there offer both novelty and variety, with Packz.io our top pick for bonus hunters and physical card collectors, BigBux.io an excellent alternative if you’re looking for more luxury oriented prizes, and Card Crush being an excellent choice for folk who favor classic casino games or digital trading card battles.
You can sign up with any of these sites today and grab a slice of the action for yourself via our official banner links on this page.
Plain and simple, mystery boxes are sealed boxes that contain completely randomized prizes - which can only be revealed by purchasing and opening the box.
Ordinarily, yes - the most trusted mystery box sites, like BigBux.io and Packz.io, will display published odds that’ll tell you the likelihood of unwrapping specific prizes.
While very, very different in terms of how they actually work, we think that PvP sites with real money prizes are a solid alternative. These sites offer arcade style games, such as Mines and Plinko, where prizes are determined according to skill based scoring methods. This makes PvP games meatier and more complex, but just as much fun. Although depending on what you’re into, you might also want to check out parimutel betting games and horse racing slots as well.
