How CS2 Raffles Work
A CS2 raffle is a lottery: a prize (skins, coins, or cash-equivalent balance) is put up, players acquire tickets — either by purchasing them directly or earning them automatically through deposits or wagering — and one ticket is drawn at random as the winner once the raffle closes.
This is structurally different from every other format on this blog. Dice and wheel games have a house edge built into a payout multiplier. Coinflip and case battles take rake from a pot. A raffle has neither — instead, the platform either profits from selling more ticket value than the prize is worth (paid raffles), or funds the prize as a marketing/retention cost tied to deposits or wagering it's already earning from elsewhere (deposit-linked raffles).
The Math — Your Tickets ÷ Total Tickets
This is genuinely the whole formula. If a raffle has 10,000 total tickets and you hold 5, your win probability is 5/10,000 = 0.05%. Hold 50 tickets in the same pool and your odds rise to 0.5% — a full 10x improvement, but still a small number in absolute terms.
| Your Tickets | Total Tickets | Win Probability |
|---|---|---|
| 1 | 10,000 | 0.01% |
| 10 | 10,000 | 0.10% |
| 100 | 10,000 | 1.00% |
| 1,000 | 10,000 | 10.00% |
Is Buying More Tickets Worth It?
Your odds scale exactly linearly with tickets held — no diminishing or increasing returns, just a straight ratio. Whether accumulating more tickets is a good use of money comes down to comparing the total revenue the platform collects from all tickets against the real value of the prize:
- If (ticket price × total tickets sold) is greater than the prize value, the raffle has negative expected value across the whole pool — the platform profits regardless of who wins, same as any house-edge game structured differently.
- If tickets are free or deposit-linked, the calculus changes entirely — you're not paying directly for entries, so any prize probability is pure additional value on top of activity you were already doing.
Buying extra tickets in a paid raffle doesn't improve your "luck" in any special sense — it just proportionally increases a fixed-formula probability, at a cost you can calculate in advance if (and only if) the total ticket count is known.
The Transparency Problem
⚠️ No total ticket count = no way to verify your odds. A raffle page showing "Your tickets: 12" without a published total, current or final, gives you no way to calculate your actual win probability. You know the numerator, not the denominator.
A transparent raffle publishes either a live running total of tickets sold/distributed, or clearly states the ticket cap and how tickets are earned so you can estimate the pool size yourself. Provably fair draw mechanics (a verifiable random selection from the ticket pool) address whether the draw itself was manipulated — they don't address whether the site is honest about how many tickets exist in the first place. Both need to be checked independently, the same principle covered in our skin upgrader risk guide.
Paid Raffles vs Deposit-Linked Raffles
You buy tickets with real balance. Requires knowing the total ticket count to judge whether the expected value is reasonable. Functions exactly like a traditional lottery.
Tickets are earned automatically from deposits or wagering volume you're already generating — no separate purchase. This is functionally closer to a loyalty/rakeback bonus than a standalone lottery, since you're not spending anything extra specifically to enter. Roobet's weekly raffle is a well-known example of this format.
Expected Value Formula, Worked Example
For a paid raffle, expected value per ticket is: (win probability × prize value) − ticket price. Here's a worked example with a $500 prize, $2 tickets, and 1,000 total tickets sold:
| Step | Calculation | Result |
|---|---|---|
| Win probability (1 ticket) | 1 ÷ 1,000 | 0.1% |
| Expected prize share | 0.001 × $500 | $0.50 |
| Ticket cost | — | $2.00 |
| Expected value | $0.50 − $2.00 | −$1.50 per ticket |
In this example, the platform is collecting $2,000 in ticket revenue (1,000 × $2) against a $500 prize — a $1,500 profit margin regardless of who wins, which is exactly what the negative per-ticket EV reflects. This same calculation works for any paid raffle once you know the ticket price, prize value, and total tickets sold — multiply total tickets by ticket price to see the platform's total revenue, then compare that to the stated prize value directly.
Estimating Pool Size When It's Not Published
If a site doesn't publish a running ticket total, you can still estimate a rough ceiling using indirect signals:
- Check for a stated ticket cap. Some raffles cap total tickets sold even without showing a live counter — the cap alone lets you calculate a worst-case odds floor.
- Look at historical winner announcements. If past raffles disclosed final ticket counts (even after the fact, in a winner announcement post), that gives you a rough benchmark for typical pool size on that platform.
- Treat undisclosed pools as a red flag, not a puzzle to solve. A platform that could easily show a running total but chooses not to is making a deliberate transparency choice — the safest response is to prefer raffle sites that do publish the number, rather than trying to reverse-engineer one that doesn't.
What Doesn't Work
"Lucky" ticket numbers
Every ticket in a provably fair draw has identical, independent odds. A ticket number ending in 7 or matching a birthday has no different probability than any other ticket in the pool.
"Entering right before the draw closes improves odds"
Odds depend only on your proportion of total tickets at draw time, not when during the entry window you acquired them. Timing entries doesn't change the ratio.
"Raffle prediction services"
As with every other format covered on this blog, a genuinely random, provably fair draw cannot be predicted by a third-party tool. Treat any service claiming otherwise as a scam risk.

⚠️ Gamble Responsibly
Paid raffles carry real financial risk regardless of ticket transparency — most entrants do not win. Never spend more on tickets than you're comfortable losing entirely. Set a budget before entering any paid raffle. Visit BeGambleAware for free support. 18+ only.
