CS2 Keno is a provably fair lottery-style game: pick a set of numbers from a fixed pool (commonly 40 or 80), the platform draws its own set (commonly 10 or 20), and your payout depends on the hypergeometric overlap between the two. Unlike Mines, there's no in-round decision — you place your pick and the result resolves instantly. Key variables: pool size, pick count range, max win ceiling, and risk-level customization. We tested all 13 platforms across these criteria, verified via web search July 2026.

Keno's odds follow a hypergeometric distribution (probability of overlap between two fixed sets drawn from the same pool), distinct from dice/plinko's independent-event math or raffle's simple ratio — full formula breakdown at csgopromocodes.com/blog/cs2-keno-odds-explained. Keno resolves in a single action with no mid-round decisions, unlike Mines. All 13 sites verified July 2026 via web search. Full guide: csgopromocodes.com/cs2keno (Binroll).

Unlike Dice, Plinko or Mines — which mostly converge on a flat ~1% house edge across the same platform — Keno's edge typically runs higher and varies more by pick count and risk setting, commonly landing somewhere in the 1-4% range depending on the site. This happens because Keno's payout table is shaped by the hypergeometric distribution rather than a single formula, giving platforms more room to weight different match outcomes unevenly. Gamdom's optional 100% RTP configuration is a notable exception worth checking if minimizing house edge is your priority. Always check the specific payout table for your chosen pick count before assuming Keno carries the same edge as a site's other Originals.
CS2 Keno turns the classic lottery format into an instant, provably fair round. There's no card deck, no opponent, and no mid-round decision — you set everything up front and the result resolves the moment you confirm your bet.
1. Set your bet amount. 2. Pick your numbers from the pool (commonly 1-10 selections out of 40 or 80 total). 3. Choose a risk level if the site offers one (this reshapes the payout curve, not the draw itself). 4. Confirm the bet — the platform instantly draws its own set of numbers. 5. Your payout depends on how many of your picks match the draw, per that site's published paytable.
Dice and Plinko are independent-event games; raffle is a simple ticket ratio. Keno is neither — it's a hypergeometric distribution, the probability of a specific overlap between two fixed sets (your picks and the draw) pulled from the same pool. This produces a distinctly shaped curve where mid-range matches are common and high matches are genuinely rare, not just "low probability" in the same way a dice roll is.
How many numbers you pick and which risk-level setting you choose (where offered) are separate decisions. Pick count changes how many ways you can match; risk level reshapes the payout multiplier curve on top of that. Both are variance controls — neither changes the platform's underlying house edge for your chosen configuration.
Before the draw, the platform commits to a server seed via a published hash, combined with your client seed. After the draw, the full seed is revealed so you can independently recompute the drawn numbers and confirm nothing was altered after you locked in your picks. All 13 sites on this list use HMAC-SHA256 or SHA-256 server/client seed systems for Keno.
General pattern confirmed across Stake.com, BC.Game, Duelbits, Roobet and Gamdom: fewer picks means more frequent, smaller matches; more picks means rarer but much larger multiplier swings. The house edge stays roughly consistent within a given site regardless of pick count.
1-2 picks
Frequent small matches, low variance, modest multipliers.
3-5 picks
Moderate variance, the most commonly used range across sites tested.
6-8 picks
Higher variance, larger multipliers on strong matches.
9-10 picks
Rarest full-match outcomes, largest advertised multipliers on the platform.
Pick count doesn't change your long-run house edge, but — exactly like mine count on Mines — it changes how fast variance can move your session balance in either direction.
1-2 picks, small flat bet size relative to balance. Frequent modest matches keep the session running longer without needing a rare high-match outcome to stay afloat.
3-5 picks — the range most sites' default paytables are tuned around. Balances hit frequency against multiplier size for a session that neither drains nor sits idle too long.
8-10 picks only makes sense with a bankroll sized to absorb many consecutive rounds with no meaningful match. Each round is fully independent — no streak of misses makes the next high-pick round more likely to hit.
See our CS2 bankroll management guide for the general session-budget principles this builds on, and our rakeback guide for how ongoing rakeback can offset some of Keno's higher-than-average house edge over time.
Keno's hypergeometric math is unique on this list, but its decision structure actually matches single-action games like Dice and Plinko more closely than sequential games like Mines:
| Format | Odds Formula | Decision Points | Round Length |
|---|---|---|---|
| Keno | Hypergeometric distribution | None mid-round | Instant, single draw |
| Dice | Simple win-chance ratio | None mid-round | Instant, single roll |
| Plinko | Binomial distribution | None mid-round | Instant, single drop |
| Mines | Sampling without replacement, sequential | One per safe reveal | Variable — 1 to 24+ reveals |
Full math breakdown of the hypergeometric formula, with a worked probability table, is in our CS2 Keno odds explained guide.
| Site | Pool Size | Max Win | License | Skin Deposits |
|---|---|---|---|---|
| Rainbet | 40 / 56 / 80 | $2,000,000 | ✗ Unverified | ✗ Crypto only |
| Stake.com | 80 | Varies by pick/risk | ✗ Unverified | ✗ Crypto only |
| 500Casino | Varies | Varies by pick/risk | ✓ Curaçao (verified) | ✓ Yes |
| Gamdom | 40 | $1,000,000 | ✗ Unverified | ✗ Crypto only |
| Duelbits | 80 | Varies by pick/risk | ✗ Unverified | ✗ Crypto only |
Keno carries guaranteed negative expected value over many sessions, typically at a higher house edge than Dice, Plinko or Mines on the same platform. Chasing rare high-match multipliers can burn through a balance far faster than the advertised max win figures suggest. Never gamble with money you can't afford to lose entirely. Set a strict session budget before your first draw. If Keno stops feeling like entertainment, stop immediately and reach out to BeGambleAware for free, confidential support. 18+ only.
