How do online mystery boxes work?

Online mystery boxes are digital boxes that contain unknown prizes. Each box has a fixed price, so you have to buy it to reveal its contents. From our experience, you could find electronics, gadgets, clothing, sports cards, and more. You may even find Mystery Coins on some sites.

Keep in mind that these mystery boxes aren’t like real money skill games. You don’t need any skills or strategies to open these boxes. Simply make a purchase that fits your budget to open them and claim your rewards.

In case you’re wondering, these boxes don’t feature real money prizes. Nevertheless, if you prefer a site that lets you play for real money, check out our guide on PVP sites with real money prizes.

The 3 best mystery box sites for US players

Now that you’re clear on how mystery box sites work, let’s look at the top options. Before we do, here’s a quick comparison table showing you the kind of prizes they award:

Packz.io – Best mystery box site for sports and Pokémon cards

Packz.io: Pros and Cons

• Short shipping time frame
• Welcome offer available
• Free card storage with no expiration

• Limited payment options

Visit Packz.io

If you’re a sports or Pokémon collector, you’ll definitely find Packz.io appealing. This mystery box site doesn’t use boxes for its prizes. Instead, you’ll find packs containing prizes for real basketball, football, and Pokémon cards. From what we’ve seen, these digital packs range from $25 – $1,000.

Plus, you can have your cards delivered or sell them back for 90% of their worth. At Packz.io, you get graded cards from industry-leading grading companies: PSA, CGC, BGS, and SGC.

New Packz.io players also receive up to $100 on their first pack. This offer is only valid if your card is less than the pack price. Plus, only packs bought for $100 qualify for this offer.

BigBux.io – Best mystery box site for gadgets and clothing

BigBux: Pros and Cons

• Several selections of Mystery Boxes
• Secure payment methods
• Offers refunds for items damaged during shipping

• No dedicated mobile app

Visit BigBux

BigBux.io is the best mystery box website for luxurious prizes. Depending on the box you purchase, you can get exclusive items, including Apple devices like iPhones, Apple Watch Series 8, and AirPods.

We also found prizes such as wristwatches, leather shoes, clothes, perfumes, a HomePod mini, and more. Furthermore, you can choose to have your items shipped to your address or sell them back to the site for instant cashback.

There’s also a feature called battle, which reminded us of Parimutuel games. You’ll compete with other players by unboxing selected boxes, and whoever has the highest worth wins. These unboxing battles are backed by provably fair technology so that you can verify each outcome.

Card Crush – Best mystery box site for playing casino-style games

Card Crush: Pros and Cons

• Over 200 online casino-style games
• Generous sign up offer
• Quality customer service team

• No mobile app

At Card Crush, things work a little differently. Its mystery boxes only come with cards and Mystery Coins as a complimentary perk. This site lets you play casino-style games using these Mystery Coins (MC). Popular titles include Joker Queen and Gravity Blackjack.

MC can also be withdrawn as gift cards and cash prizes once you meet the minimum threshold and 1x playthrough requirement. As for the cards, you’ll use them to build your deck and fight battles against other players. These cards have different levels and can be upgraded over time. Card rarity includes: Common, Rare, Epic, and Legendary.

When you sign up, you’ll get 2 MC and a 66% discount on your first optional mystery box purchase.
