What Is Rain.gg?
Rain.gg is a CS2 case site that launched in 2023 and is run by Make It Holdings Limited (Belize). You top up with crypto, cards or skins, play cases, battles, Double or the upgrader, and cash out in crypto or skins.
It doesn't try to be a casino. Where other sites stack up 15+ originals, Rain keeps it to four modes and puts its effort into the reward side instead: three races running in parallel and a rank system that upgrades your free cases.
Is Rain.gg Legit?
Mostly yes, but with clear caveats. Here's the full picture.
- Transparent on the maths. Rain confirmed its house edges directly: 6% on Double, 10% on cases and upgrader. Most sites in this space won't give you a number at all.
- Provably fair. Rolls use a server seed, client seed and nonce. Battles also use a public EOS block hash, so you can check results after the fact.
- A named operator. Make It Holdings Limited (Belize, reg. 45313), live since 2023.
Game Modes
Four modes, all built around skins. That means fewer distractions and faster rounds.
House Edge & RTP

- Source
- Confirmed by Rain
| Game | House edge | RTP |
|---|---|---|
| Double | 6% | 94% |
| Case Opening | 10% | 90% |
| Case Battles | 10% | 90% |
| Upgrader | 10% | 90% |
These are normal numbers for the category, not cheap ones. A 10% edge means roughly 10 coins lost per 100 coins played over time. Double at 6% is the lowest-edge game on the site. What makes Rain worth playing is the reward stack on top: races and rank cases pay some of that edge back to regular players.
Races: 130K Coins Every Month
Rain runs three wager races at the same time. Everything you wager counts toward all three, and the top of each leaderboard splits the prize pool.
Rewards, Ranks & Vault
- Rank system: Bronze to Obsidian. Ten tiers, each with its own levels. You earn XP by wagering. Every rank-up automatically upgrades your free cases to a better tier. From Diamond upward you get a dedicated VIP host and invites to Rain events.
- Daily, weekly & monthly cases. These are free cases you can claim every day, week and month. You can also switch to Stacked Daily, which gives you one extra daily case per rank you've reached, with lower volatility. You need Bronze V and a linked Discord account to unlock them.
- Vault. A separate place to park part of your balance so it isn't sitting in your playable balance. It's useful if you want to lock in a win before you keep playing.
- Rain in chat. Free coins are rained on active chat users throughout the day. This is where the site gets its name.

Withdrawals

- Skins
- Skindeck & Skinsback
- Fiat
- No
There are two ways out. You can redeem CS2 skins through Skindeck or Skinsback, two external skin marketplaces, or cash out in crypto directly from Rain with 15+ coins. There's no bank or PayPal payout.
Crypto is the cleaner route: no item stock to worry about and no Steam trade hold. Skins make sense if you actually want the item.
Final Verdict
Rain.gg is one of the most rewarding CS2 case sites if you play regularly. 130K coins a month across three races, free cases that upgrade with your rank and rain drops in chat add up to a reward stack few sites match. Rain is also upfront about its house edge.
What holds it at 4.0 is trust. There's no licence, the Trustpilot score is weak, and KYC can kick in early. The edge itself is standard rather than low.
