Why use a case simulator

Every CS2 case in one simulator

42 CS2 and CS:GO cases with current contents and live drop prices. Pick any case, open it for free, compare the official odds with case-site payouts and see how much of every 100 you spend comes back.

Official CS2 odds

Valve disclosed the rarity odds: 79.92% Mil-Spec, 15.98% Restricted, 3.2% Classified, 0.64% Covert and 0.26% for a knife or gloves. The CS2 case simulator uses exactly those numbers; wear and StatTrak™ follow real unboxing statistics.

Test the odds of any case site

The “Like sites” mode mirrors the typical 90% return of case roulettes, and a custom RTP goes from 20% to 300%. You can see how far a site with “generous” cases is from the game’s honest odds before paying there.

Free and risk-free

Open cases for free as many times as you like: nothing is charged or awarded, session stats live only in your browser. Drop prices are live best offers across markets, so the result reflects real skin values.
