Rain.gg Review

A clean CS2 case site with a withdrawal problem

Rain.gg is a CS2 case site for adults (18+): cases, case battles and an upgrader, with skins, crypto or a card in and skins or crypto out. It launched in 2024 and players like how it looks. One four-star Trustpilot review calls it the "best ui for gambling".

Two things matter more than the design. Its cases keep a steady 10% on average, which is the industry norm. And its Trustpilot score is 1.6 out of 5 from 179 reviews, most of the bad ones about accounts banned or locked when the player tried to withdraw. We haven't deposited or withdrawn on Rain.gg ourselves, so everything below comes from its own pages, checked on 25 October 2026, and our own data.

Who runs it, and the "Coins" wording

The terms (last changed 13 December 2024) name Make It Holdings Limited, registration number 45313, in San Pedro, Belize, as the operator. Payments may be handled by Make It Entertainment Limited, registration number 758444, in Dublin, Ireland. Irish law governs the terms, and disputes go to private arbitration with a class action waiver. We found no gambling licence named anywhere on its pages, so there is no regulator to complain to if support won't help.

The terms are written like a US sweepstakes site rather than a casino. Your balance is Coins, which "carry no actual monetary value". Games are "contests", cashing out is a "redemption", and the US is served except Nevada and Washington. Those are the only places the terms name, and the US is Rain.gg's largest market at about 15% of visits, ahead of Germany, Norway and Sweden. In practice you still pay in with cards, crypto or skins and take skins or crypto out, so treat it as gambling. Check your own local law before you sign up. The terms say that's your responsibility.

Read this before you deposit

Two lines in the redemption rules decide what you can take out:

• "Deposited funds cannot be redeemed." Only winnings can be cashed out.
• "All Coins must be completely wagered" before any redemption. We read that as putting your whole balance through the games at least once before you can withdraw anything.

So you can't deposit $50, change your mind and withdraw it. At a 10% edge, betting $50 once costs about $5 on average before you're even allowed to cash out.

KYC ("know your customer", an ID check) is done through Sumsub, and the AML page lists a government ID, proof of address and a face scan. The terms make KYC mandatory for crypto redemptions that come from card or bank (fiat) deposits. If you deposit by card and want crypto out, expect to send ID first. Doing it before you play, while your balance is small, beats doing it after a big win.

What the cases keep

The house edge is the share of each case price the site keeps on average. A 10% edge means $100 of openings returns about $90 in items over time. We measured all 675 paid Rain.gg cases on 1 October 2026, using Rain's own item prices and odds:

	House edge
Average	10.3%
Median	10.0%
Lowest case	10.0%
Highest case	22.9% (Wasteland)

No case comes in under 10%, and 621 of the 675 sit between 10% and 11%. That's more than CSGOEmpire (8.8%), CSGORoll (9.1%) and Clash.gg (9.9%) keep on average in our measurements, about the same as Skin.Club (10.0%), and well under Hellcase (12.5%).

The exceptions are the cheapest cases. The 25 cases priced under 1 coin average 11.9%. Wasteland costs 0.07 coins and keeps 22.9%, Vortex (0.13) keeps 16.8%, Mellow (0.23) 13.5% and Pocket Burner (0.29) 13.2%. If you like penny cases, these are the worst value on the site.

These numbers use Rain's own item values. If it prices items above what they sell for on the big marketplaces, you lose more when you withdraw them as skins. We haven't compared Rain's item prices with the market.

Upgrader lets you stake skins or coins for a chance at an item 1.5x to 20x the value, and you can keep the win as balance or send the skin to Steam. We haven't measured its edge. The terms still describe a Double roulette game (2x or 14x), but the site menu now shows only cases, battles and upgrader.

Battles and provably fair

Case battles put two to four players on the same cases, and the player who secures the most valuable item takes every item opened. They carry the edge of the cases inside them. Rain says its games are provably fair: you see a hashed server seed before the round, and battles use a future EOS blockchain block hash, so you can check afterwards that the result wasn't changed. That proves a roll wasn't altered. It doesn't stop the site closing an account.

Free cases, Treats and the code

Free cases need a linked Discord account and either the Bronze V rank or the "Free To Play" activation. After that, every coin you bet earns XP across 11 ranks, from Bronze at 12,500 XP to Obsidian at 4.5 billion. You choose daily, weekly and monthly cases or a stack of daily ones. Rain says both have similar average returns.

There's no rakeback percentage. Instead, bets have a chance to earn Treats, from 1% on a 0.20 coin bet to 50% on a 10 coin bet, with rank multipliers up to 2.1x. Treats open cases in a separate shop. Rain doesn't say what a Treat is worth, so we can't turn this into a rakeback figure.

Code btrf is our affiliate code, and Betrefs earns a commission on play under it. Rain's affiliate page says any affiliate code gives 3 free cases after a successful deposit and a 5% bonus on cash deposits. On a $50 deposit that's $2.50, and under the redemption rule it has to be wagered like the rest of your balance. It doesn't cover the edge on the bets you need to make to cash out.

The complaints

The pattern in recent reviews is the same. In September a player says they turned 5 euros into 100, were banned when they tried to withdraw, and were told "if u like u can complete kyc and get ur account back", then blocked again. In July one says a 4,000 euro win led to a permanent ban, and another says they were banned as soon as they tried to withdraw. An August reviewer, down "6k" by their count, says they were banned from promos with no reason given.

We can't verify any of these, and 179 reviews is few for a site with about 2 million visits a month. The terms do allow what they describe: Rain.gg can void results, disqualify players "for any reason at our sole discretion" and, after a breach, withhold funds to cover its costs. Traffic has also fallen, from about 3.1 million visits in March to 2.1 million in August.

Should you play?

On cases alone, Rain.gg is an average-priced site that's pleasant to use. The risk is at the end: winnings only, the whole balance wagered first, ID on card-to-crypto cash-outs, no licence, and a run of reports of bans at withdrawal. If you play anyway, keep deposits small, finish KYC before your balance grows, skip the sub-1-coin cases, and withdraw winnings as you go. Self-exclusion is on the site and can't be undone early, which is how it should work.
