Mystery box sites are all the rage right now, especially because they’re often available even in states where online gaming is off limits. But what are these sites all about, and how do you choose the best ones to use?
These are online sites where you purchase mystery boxes to reveal random prizes rather than buying a specific product from the start. We’ve put this guide together to help you navigate this space. You’ll get to know everything about mystery box sites along with three of our top recommendations you can register with – Packz.io, BigBux.io, and Card Crush.
Similar to sites offering real money skill games, mystery box sites are becoming increasingly popular for many reasons. It’s still good practice to know their pros and cons before deciding to register with one.
You may have come across mystery boxes while playing online games, where they could reveal special in-game prizes, or even in retail stores, where you pick a box without knowing what’s inside.
Online mystery box sites are quite similar. Just as the name implies, you’ll purchase a box that contains one or several random items from a preset group of possible prizes.
The exact contents of the box aren’t entirely predictable, so you won’t know exactly what you’ll pull until you open it. But online mystery boxes are often grouped, so you at least know what category your prize falls under and the percentage chance of pulling each item.
Online mystery boxes usually have fixed price ranges and are often grouped into tiers. So you can go for lower-priced boxes if you prefer, or switch to higher-priced options that usually come with prizes that are of higher value. Some sites, including a few we’ll be recommending here, also offer a discount on your first mystery box purchase.
The items inside these boxes could be frankly anything, but it’s simple to get a hang of how these sites work. You just select a themed box, pay, and open it to reveal your reward. Remember that what you pull is random.
If you’re wondering which mystery box sites are good to use among the myriad of options, we’ve got you covered with some of the best ones. You can easily check out any of these three sites and their online mystery boxes using the corresponding banners on this page. But before you go off, here’s a detailed review of each site and what it’s best used for.
| Mystery box sites | Best for |
| Packz.io | Trading card packs like sports and Pokémon trading cards |
| BigBux.io | High-value boxes in categories like tech, cars, luxury items, and to engage in player-vs-player unboxing games |
| Card Crush | Collectible cards and casino-style solo gaming |
Packz.io could be your go-to if you want sports trading card packs and Pokémon trading card packs. These are the main categories it offers, and we’ve found mystery boxes with prices as low as $25, although the options go way up to $2,500 for better value boxes. Packz.io is also verified by authenticators and graders like the Professional Sports Authenticator (PSA) and Beckett Grading Services (BGS). So you know you’re using a legit site.
With the sports packs, you’ll find trading cards from the MLB, NBA, NFL, and international leagues. Any pack you select has its odds distribution that basically tells you the value ranges it might have and the percentage chance of each. For instance, the sports starter pack has several ranges, with a 25% chance of getting a prize valued between $18 and $25, and a 0.1% chance of getting a prize worth $250 to $500 with your $25 purchase.
The welcome offer for new users at Packz.io is a 100% buyback on your very first pack. This means you can sell back a mystery box you don’t like, and you’ll get all the initial cost refunded as site credits, right up to $100.
BigBux.io goes beyond just trading cards by offering mystery boxes spanning categories like tech, luxury, watches, motorcycles, cars, gaming, and lots more.
Not only do you trade cards, but you can also take part in player vs player unboxing battles, where the winner is the one who reveals the higher value prize. This is different from what you’ll find at PvP sites with real money prizes.
BigBux.io online mystery boxes have a wide range of prices so you can choose whatever suits your budget.
When you purchase a mystery box, you’re allowed to choose from three reward options. Either you get just the items, Experience Points (XP), or a combination of both. Any choice you make is equal to or more than the value of the box you’ve purchased. XPs can be exchanged for mystery boxes.
Mystery boxes here can offer up prizes like cards, Mystery Coins, or both, rather than physical prizes you’ll get on other sites. Cards are used to build a deck and compete with other players in daily and weekly tournaments. Mystery Coins, on the other hand, are used for solo gaming across casino-style games.
Newly registered players will collect a welcome reward of 5 Cards and 2 Mystery Coins, along with a 66% discount on your first mystery box purchase. If you’re curious about parimutuel games, we have a guide that you may find interesting.
Online mystery boxes can consist of virtually any prize and span several categories like gaming, tech, sports, and a host of others. If it’s valuable, chances are there’s a mystery box for it. Here are the most common ones you’ll find:
As you’ve seen, mystery box sites do have some fantastic perks as you can get more value at a fraction of the box price. But remember that you can also receive prizes that are lower than the value of the box since it could swing both ways. This unpredictability, the excitement of unboxing, along with the chance of getting valuable rewards, is one of the main reasons mystery box sites have become mainstream.
We’ve recommended Packz.io, BigBux.io, and Card Crush as the top mystery box sites available right now. They all serve up a fun, reliable experience and are superb options to consider if you’re searching for the best sites to use.
