500 Casino — a CS2 skin casino, explained
500 Casino (also known as CSGO500) is one of the longest-running CS2 (CS:GO) skin gambling sites. It combines three things in one balance: classic case opening, a set of casino game modes (roulette, crash, dice and more), and a P2P marketplace where you deposit and withdraw CS2 skins to and from your Steam inventory. You sign in with Steam, fund a site balance with crypto, a card or skins, and cash out winnings as skins or crypto. Every mode on the platform is a chance-based activity for adults (18+) with a negative expected value — the house always keeps an edge.
How case opening works
Each case holds a fixed list of CS2 skins, and every item has a published drop chance. You pay the case price, 500 Casino draws the result with its provably fair engine, and you receive the skin the draw lands on. Common blue and purple skins are likely; rare red Covert skins, knives and gloves such as the Dragon Lore, Howl or Karambit Fade sit at long odds. Because the weighted average of all outcomes is below the case price, case opening is a losing game on average — the rare big win is paid for by many small losses.
The casino game modes
Beyond cases, 500 Casino is built around casino-style modes played with your skin balance. They are faster than opening cases and swing harder, but the math is the same: each one has a house edge, so the expected value is negative.
| Mode | How it plays | Note |
|---|---|---|
| Roulette | Bet on a colour or number; a wheel decides the result | The classic 500 game; a green slot is the house edge |
| Crash | A multiplier rises; you cash out before it crashes | Cash out early for small wins, late for big risk |
| Dice | Pick a target; roll over or under it | You choose the chance and the payout |
| Case Battles | Two or more players open the same cases at once | Highest (or lowest) combined value takes all |
Case battles get their own Games & Battles page. Whichever mode you pick, the sensible approach is the same: set a budget first, treat it as entertainment, and stop when it stops being fun.
Odds and rarity
CS2 items sit on a rarity ladder, and case pages weight their drops along it. As a rule, the better the tier, the lower the chance:
| Rarity tier | Colour | Typical drop weight |
|---|---|---|
| Mil-Spec | Blue | Most common |
| Restricted | Purple | Less common |
| Classified | Pink | Rare |
| Covert | Red | Very rare |
| Knives / Gloves (★) | Gold | Rarest — a fraction of a percent |
The exact percentages differ from case to case and are shown on the platform before you open. The number that matters is the chance of the item you actually want — not the headline jackpot.
The P2P skin marketplace: deposit and withdraw
The feature that sets 500 Casino apart from a pure case site is its P2P marketplace for CS2 skins. Instead of the site holding an inventory, players trade with each other: you deposit skins to turn them into balance, and you withdraw balance by buying skins that other users list, which are then traded to your Steam inventory. It is the main way to cash out, and it runs on top of normal Steam trades, so a valid trade link and Steam Guard are required. The full step-by-step flow — deposit, withdraw, holds and limits — is on the P2P Withdraw page.
Deposits, withdrawals and the trade hold
You usually fund balance by crypto, card or a skin deposit; winnings leave as CS2 skins to your Steam inventory or as crypto. For skins you need a valid trade link and Steam Guard. Steam applies a trade hold of up to seven days, which gets shorter once the Steam Guard mobile authenticator has been active long enough. 500 Casino does not take your Steam password — sign-in runs through the official Steam OpenID.
| Method | Speed | Note |
|---|---|---|
| Crypto | After network confirmations | Often the lowest fees; fastest to withdraw |
| Card (Visa/Mastercard) | Instant deposit | May carry a processing fee |
| Skin deposit (P2P) | After the trade completes | Valued at the current market price |
| Skin withdrawal (P2P) | After a buyer and the trade hold | Skins traded to your Steam inventory |
Provably fair and security
Each result is produced by a provably fair system (server seed, client seed and a nonce) that you can verify afterwards, so the outcome cannot be changed after it is committed — the whole process is on the Provably Fair page. For safety, sign in only through the official Steam login, keep Steam Guard active, check the domain in the address bar, and never trade outside the platform.
Bonuses, promo codes and rewards
500 Casino offers a daily free case, rakeback, level rewards and a promo code that adds bonus balance — small tries with their own conditions and cooldowns, described on the Bonuses page. None of it changes the underlying math: case opening and the casino modes are entertainment with a built-in house edge. Before you start, set a budget, read the odds, never chase losses, and use deposit limits and cool-off tools. Access is strictly 18+.
RTP and the house-edge math
Every case and every mode has an implied RTP (return to player) — the share of staked value that flows back to players over the long run. If a mode has a 95% RTP, you get back about 95 of every 100 units staked on average, and 5 is the operator margin. The exact numbers vary, but the principle never changes: RTP is below 100%.
| Rounds | Staked | Avg return (95% RTP) | Expected difference |
|---|---|---|---|
| 10x | 1 000 | ~950 | -50 |
| 100x | 10 000 | ~9 500 | -500 |
| 1000x | 100 000 | ~95 000 | -5 000 |
The more you play, the closer reality gets to that average — the law of large numbers. Short lucky streaks happen, and they are the moments that make it exciting, but over the long run the total drifts into the red. No betting pattern raises the RTP.
Playing on mobile
500 Casino runs in the web browser, so on a phone there is nothing to install — a Steam sign-in is enough. Case opening, the game modes, battles and withdrawals work as they do on desktop. On mobile the basic safety rules count double: sign in only through the official Steam login, keep the Steam Guard mobile authenticator active (it also shortens the trade hold), and check the domain before you confirm anything.
The most common beginner mistakes
- Chasing losses: staking more after a bad run to get back to even. The math is against you — it only widens the swings.
- Playing without a budget: starting with no limit set in advance. Set it before you open the first case.
- Believing in hot games: drops and rounds are independent; no case or roulette wheel is due to pay out.
- Grinding crash multipliers: re-staking winnings until they are gone.
- Trading outside the platform: the most common route to a scam. Never trade through links from messages.
Account security checklist
- Sign in only through the official Steam OpenID — never type your password on another page.
- Keep Steam Guard active, ideally the mobile authenticator.
- Check the domain in the address bar before every sign-in.
- Set up your trade link and confirm you only send trades to the verified platform.
- Ignore free-win offers and links from unknown messages — these are typical phishing attempts.
