Before you deposit on Clash.gg
- Clash runs on Gems. There's a Purchase button in the top bar: you buy Gems, play with Gems and redeem Gems for skins or crypto.
- One player's review says the 3 free cases only opened after a deposit. Check what the welcome page asks of you before you top up for them.
- Card deposits: one player says they got 5% extra with a code but paid a 10% fee on the card deposit. Crypto or skins avoid that.
- Withdrawals are CS2 or Rust skins, peer to peer, or crypto.

Is Clash.gg legit?
It's a big, long-running site with a founder you can name: Hobbes, a long-time Rust and CS player, whose team also runs RustClash and Cases.gg. The operator on its site is Rust Clash Entertainment Ltd. Its games are provably fair, and it publishes no gambling licence.
On Trustpilot it scores 2.9 out of 5 from 853 reviews: 60% five-star and 34% one-star. The one-star reviews share a theme: verification requests after a win, an account flagged as suspicious and a withdrawal that didn't come. We haven't tested Clash with our own money, so withdraw as you go rather than letting a big balance sit there.
