Calculators that default to the cost
The numbers sites don't put on the case page. All run locally in your browser; nothing you type leaves it.
Case EV Calculator
Expected value, RTP and profit chance for any case.
Rakeback Calculator
What 10%, 40% or 70% rakeback is actually worth on your turnover.
Roll Odds Calculator
Green-in-N odds, streak probabilities and expected loss.
Upgrader Calculator
Exact upgrade chance, multiplier and cost per attempt.
Roll = 15 slots, 1 green. Every colour has the same 6.67% edge.
What is SkinsRoll?
SkinsRoll is a free simulator of the games you find on CS2 skin gambling sites — above all CSGORoll, which is why the domain says "roll". You get ◎1,000 fake coins, stored only in your browser, and can open cases, spin Roll, ride Crash, drop Plinko balls, roll Dice and attempt upgrades as long as you like. Nothing is deposited and nothing is paid out.
The point is to see the mechanics before money is involved. Real skin sites are an expensive place to learn: a case is 10% house edge, Roll is 6.67%, the Upgrader compounds. Every demo here prints the number, and the calculators turn it into coins-per-hour for the way you actually play.
Then, the codes
If you do decide to play for real, we list working promo codes for five sites — CSGORoll, Duel, Thrill, CSGOEmpire and 500.casino — with plain instructions on where to enter them. Our reviews score each one out of 10, but the "best" site depends on whether you want free cases (CSGORoll), rakeback (Thrill, Duel, 500) or a big welcome case (CSGOEmpire). Those are affiliate links and we earn a commission, which is the only way the site makes money.
House edge at a glance
| Game | Edge | Per ◎1,000 wagered |
|---|---|---|
| Dice / Crash / Plinko | 1% | ◎10 |
| Roll | 6.67% | ◎67 |
| Upgrader | ~10% | ◎100 |
| Case opening | 8–15% | ◎80–150 |
Is this gambling?
No. Gambling needs a stake of value, chance, and a prize. SkinsRoll has only the chance. That also means a hot streak here predicts nothing anywhere else — each real round is independent, and the edge is always there.
What is SkinsRoll?
A free CSGORoll-style simulator: case opening, Roll, Crash, Dice, Plinko and Upgrader played with fake coins, plus four calculators that show the real cost. No account, no deposits, nothing paid out.
Is SkinsRoll affiliated with CSGORoll?
No. We're an independent site. We link to CSGORoll and other brands with affiliate codes and earn a commission if you sign up — that's how the site is funded.
What is the CSGORoll promo code?
GETBOX. It gives a 10% bonus and 3 free cases. Enter it under Rewards → Affiliate before your first deposit.
Can I win real skins here?
No. Balances are fake coins stored in your browser. To play for real, use the brand links — 18+ only.
Which skin site has the best bonus?
It depends on how you play: CSGORoll (GETBOX) for free cases and a deposit bonus, Thrill (maxrakeback) for up to 70% rakeback, CSGOEmpire (case2go) for a free welcome case up to $1,500, 500.casino (CSMAX) for a 300% rakeback boost up to $15,000, Duel (MAXRB) for rakeback on every wager.
Are the demo odds real?
The formats and formulas match real sites: 15-slot Roll, 99/chance Dice, binomial Plinko, value-ratio upgrader. Exact case contents are ours; paste real ones into the EV calculator.

Glossary
- House edge
- The share of every wager the operator keeps over the long run. 1% edge = ◎10 expected loss per ◎1,000 wagered.
- RTP
- Return to player — the mirror of house edge. 90% RTP on a case means a 10% edge.
- Expected value (EV)
- What a bet is worth on average: sum of (payout × probability). Always below the stake on a real site.
- Variance
- How much results swing around the average. High variance = long dead runs, rare big hits.
- Provably fair
- A seed-hash system letting you verify a result was fixed before your bet. Proves honesty, not good odds.
- Rakeback
- A percentage of the house edge you generate, returned regardless of win or loss.
- Wagering requirement
- Turnover you must generate before bonus balance becomes withdrawable. 20× on ◎100 = ◎2,000.
- Case Battle
- Several players open the same case; the highest total takes everything. EV per case is unchanged.
- Upgrader
- Trade an item for a chance at a pricier one. Chance = value ratio × (1 − edge).
- P2P withdrawal
- Skins bought from other users' listings instead of site stock — faster and deeper inventory.
