- 1. The RTP is close to 99.9%, making it one of the fairest upgrader implementations in the industry in terms of expected value.
- 2. Despite the favorable RTP, there is no provably fair algorithm supporting this game mode, so users cannot independently verify the randomness of outcomes.
- 3. Users can upgrade up to 3 unboxed items at once (not credits) and choose their target item from Rillabox's large catalog using filters, price ranges, and search. The upgrade probability must be set between 1–90% to proceed.
Looking for a way to turn your small wins into serious prizes? The Upgrader mode on Rillabox gives us the shot to swap lower-value items for premium gear.
It's instant. It's transparent. And in 2024, Rillabox processed over 2.3 million unboxings from 700,000 users worldwide.
The Upgrader game mode (sometimes called "Deals") lets us swap smaller prizes like Apple stickers for bigger ones, such as real iPhones, straight from online mystery boxes. Pick a target product or multiplier and Rillabox instantly shows our chance of winning.

Please note that upgrader (or "deals") is a very Casino-inspired game mode and tends to be highly addictive. Be very cautious and if you encounter any health related issues stay clear and seek professional help instead.
The odds depend on how much value sits between what we have and what we want. If that gap gets huge, expect our chances to shrink, sometimes all the way down to 1%.
This let's us upgrade our unboxings in no time, like when we tried to upgrade our McLauren Pinbadge for a watch and lost.
But on the second try it worked:
And traded it up to Casio watch:
Playing with higher-value vouchers or combining up to three items at once makes success feel within reach. A high RTP of 99.9173% means almost all stakes get paid out in wins over time. That's rare.
Is upgrading products actually worth it?
Yes, if you understand the odds and play smart. Upgrading on Rillabox gives us real chances to win items worth far more than what we put in.
The platform's 99.9173% RTP is among the highest in the mystery box industry. To put this in perspective, most land-based casino slots have RTPs between 90% and 92%, according to gaming regulators.
Upgrading items on Rillabox feels like wagering at a live casino table, where tiny Apple logo stickers can become real iPhones. Our odds may go from 1% up to 90%, so picking each mystery box and voucher takes guts and luck.

Please note that we couldn't find any information regarding provably fair used in their upgrade game mode. Therefore we can't guarantee the RTP rate and any upgrades are legit.

How we can turn $2 Apple logo stickers into a real iPhone on Rillabox
After going for a watch, we thought... "why not go for an iPhone with just stickers?"
And that's what we tried with couple of leftover stickers from our Apple mystery boxes.
Turning a $2 sticker into a real iPhone is wild, but it's very possible on Rillabox:
- ->We open online mystery boxes and win Apple logo stickers for around $2 each.
- ->Using the Upgrader mode, we pick our $2 Apple sticker and add other low-value items like a $0.15 RillaBox Voucher or even things like a Moncler Badge Sticker.
- ->Our eyes lock on the iPhone SE 2nd Gen, Black, 64GB, priced at $144.99 as the upgrade target.
- ->The total value of our selected items for this shot comes to just $1.93 while the possible reward stands tall at roughly $145.11.
- ->Every attempt gives us a clear chance. Here it's exactly 1.33% to grab that iPhone.
- ->We tried, but weren't lucky:
- ->We tried another time, but without success:
So this game mode is definitely not free money.
But it can be a lot of fun, and turn a bad unboxing into a great product.
