A Russian-first upgrader that grew to 4 million visits
Upgrader.Pro is a gambling site for adults (18+) built around one game, the skin upgrader. You stake value, pick a more expensive skin as the target, and the site shows your chance of getting it. Win and the target is yours. Lose and the stake is gone in one click.
There is also a battle mode. When we checked its public live-drop feed on 25 October 2026, 18 of the 20 latest wins came from upgrades and 2 from battles, and the site's own counter put its totals at about 566 million games and 486,000 battles.
It is big for a young site. Our traffic data shows about 2.9 million visits in June 2026 and 4.1 million in July, with Russia, Poland and Ukraine as the top countries. It is built for that audience first: the homepage's default title and description are in Russian, and the page lists upgrader.best as its version for Russia and upgrader.life for Ukraine, while upgrader.pro carries English, 12 other languages and a Russian-language /cis section. Mirror domains like these are common on sites that get blocked in some countries. If you play, note which domain your account and balance live on.
Who runs it
The site's footer names ITSFAIL LTD. One private company with that exact name is on the UK Companies House register (number 13246765). It was incorporated in March 2021, is listed under internet retail rather than gambling, and has a single active director who lives in Ukraine. We couldn't read a company number on Upgrader.Pro itself, so we can't confirm it is the same company. The name hints at a link to CS.Fail, which we couldn't confirm either.
We found no gambling licence. A company registration is not a licence, so there is no regulator to take a complaint to if support doesn't help.
Our data lists 2026 as the launch year, but the earliest archived copy of the English site we found on the Wayback Machine is from 22 November 2025. Older copies of the upgrader.pro domain look like a different site. Its Rust sister site, Rustgrade, comes from the same team and is not provably fair.
How the upgrader works, and what it keeps
The fair chance of an upgrade is your stake divided by the target's value. Put a $10 skin towards a $20 skin and a fair game gives you 50%. Whatever the site shows below that is its house edge, the share it keeps on average. On the upgraders we have checked at CSGORoll, Key-Drop and Hellcase, the gap works out to 10%, so the same $10 to $20 upgrade shows about 45%. Clash.gg's FAQ states 7.3%.
Upgrader.Pro publishes no edge that we could find, and checking it needs a logged-in account, which we haven't done. Our listing describes it as low-edge, but until we have a shown chance next to two known prices, treat that as unproven. You can do the check yourself before the first spin: divide the stake by the target value and compare it with the chance on screen.
The highest chance among the 20 recent wins in its live feed was 78.54%, which suggests upgrades stop at around 80%. Even at 80% you lose one time in five. Losing seven 78% upgrades in a row, which one player describes, has odds of about 1 in 40,000 on a single run of seven. That is rare for one person and not impossible across millions of players, and a review can't prove either way.
The site says its results are provably fair: after a round you can check that the outcome came from seeds fixed before you bet. That shows a round wasn't changed afterwards. It tells you nothing about the edge, and it doesn't help with the complaints below, which are about getting money out.
Deposits and fees
| Method | Deposit fee in its payment list (25 October 2026) |
|---|---|
| CS2, Dota 2 and Rust skins | None |
| Crypto: BTC, ETH, SOL, BNB, TON, TRX, MATIC, and USDT on TRON, BSC, TON, Ethereum or Polygon | None |
| Gift cards (paysafecard, Skrill, Revolut and others) | None |
| Card, Apple Pay, Google Pay | 3% |
| PrivatBank and Monobank QR (Ukraine) | 8% |
There are local methods too: BLIK in Poland and PIX in Brazil are 3%, and the SBP QR codes in Russia show no fee. A $100 card deposit costs $3, so skins and crypto are the cheaper ways in.
Skin deposits are free, but you are credited at the site's own price for the skin. A player in August says deposited skins are valued low and withdrawn skins cost more. We haven't compared its item prices with the market, so check the credit offered against a marketplace price before depositing anything valuable.
You cash out as CS2 skins or crypto. Our data doesn't list withdrawals as instant.
"No KYC", until you win
KYC ("know your customer") is an ID check: a passport or ID card, sometimes a selfie. Our data, taken from the site, says it isn't needed to sign up, deposit or withdraw. Upgrader.Pro has 2.2 out of 5 on Trustpilot from 167 reviews, the recent ones almost all 1-star, and the most specific describe checks appearing after a win.
On 19 September a player says they won an M9 Bayonet Night worth $569.39, tried to withdraw it straight away and were blocked with an "account restriction" anti-fraud error, then refused a refund. A day earlier, a player says a $250,000 win led to a request for many documents and a wait of more than 10 days with no answer. Another from 19 September says "verification" only came up after a big run. Other reviews say small deposits win and bigger ones lose.
We can't verify any of this, and 167 reviews is a small sample for 4 million visits a month. The pattern that matters is the one about wins: a site that says no KYC but checks players after they win big leaves those players with no licence or regulator to appeal to.
VIP cashback instead of a code
There is no Betrefs code and no rakeback. Its VIP page sets your status from the last 30 days of deposits and pays weekly cashback on that week's deposits every Friday: up to 5% at Silver, 7% at Gold, 10% at Platinum and 15% at Diamond. From Gold you can ask a VIP manager for a 5% to 10% bonus before topping up. The level thresholds have no currency label, and we don't know whether the cashback or the bonus comes with wagering rules. Ask before you accept either, and remember that a reward based on deposits pays you for depositing more.
If you play
Start with skins or crypto to avoid the card fee. Work out the fair chance before each upgrade, and only stake skins you would be fine losing. Withdraw wins as you go, so less is at risk if an anti-fraud check lands on your account, and keep your ID ready in case one does.
