Which cases are actually worth opening, ranked by resale value and drop odds.
We rank CS2 cases by the resale value of the skins inside, not by how new or flashy they are. S-tier = discontinued cases with expensive covert/knife drops; D-tier = cheap, common cases with low-value skin pools. Exact ROI shifts as market prices move, so always re-check the Steam Market before opening.
A case's tier is not about how it looks — it's about what the skins inside actually resell for and whether the case still drops. Two factors dominate:
The standard rarity odds apply to every case, so ROI swings almost entirely on these two factors plus the current case price. For live community discussion of case prices and which ones are appreciating, see r/csgomarketforum and r/GlobalOffensive.
Here's how cases rank by the same value logic we apply across the site. Exact ROI moves daily with market prices, so treat this as a framework and re-check live prices before opening.
| Tier | What's in it | Why |
|---|---|---|
| S | Discontinued cases with high-value coverts/knives (e.g. older operation cases, discontinued Chroma/Breakout-era cases) | Scarce skins, appreciating prices, highest expected value |
| A | Recent cases with strong red drops (e.g. Dreams & Nightmares, Fracture, Recoil, Revolution, Kilowatt) | Good coverts, still dropping so cheaper to buy into |
| B | Active cases with decent but lower-ceiling pools (e.g. Snakebite, Prisma 2, Danger Zone, Prisma) | Reasonable but not standout coverts |
| C | Cheap, common cases with low-value skin pools | High supply, weak resale value |
| D | Cases whose top drops are low-tier weapons | Worst expected value — skip |

Every standard case uses the same published drop rates regardless of tier — roughly 79.9% blue, 16.0% purple, 3.2% pink, 0.64% red, and 0.26% for a knife (about 1 in 385 openings). Because these odds are fixed, a case's tier is driven almost entirely by the resale value of its skins. See the exact breakdown in our CS2 case odds guide.
Treat case opening as entertainment with a small chance of profit — never as income. The house edge guarantees losses over enough rolls. Open S- and A-tier cases only after pricing their skin pools, use free daily cases and deposit bonuses on Hellcase, and set a budget. See whether opening even beats buying skins directly in our case vs buying comparison.
S-tier: discontinued cases with high-value covert or knife drops. Their skins appreciate once the case stops dropping, giving the highest expected value. Re-check live Steam Market prices before opening.
Discontinued cases with expensive coverts dominate S-tier. Exact picks shift as prices move — see our best CS2 cases ranking for the current top cases by 30-day market average.
Roughly 0.26% per case — about 1 in 385 openings. This is the published standard rate and applies across all official and most third-party cases.
Not usually. Newer cases still drop, so their skins are cheaper and more common. Discontinued cases with high-value coverts generally offer higher ROI — that's the whole S-tier logic.
Mathematically, buying the skin you want usually beats gambling for it. See our case vs buying ROI comparison for the full breakdown.
