## Catalog changes · price, advertised RTP and contents, per capture

| Captured | Price | Advertised | Items |
| --- | --- | --- | --- |

Each opening is tested against the capture in force when it happened; a price or odds change starts a new one.

listed best hit $701 (1,002x)

**Case opening is gambling with skins as the currency.** At 84.2% RTP, every $100 put into cases returns $84.19 on average: an expected loss of $15.81 per $100, before any one lucky or unlucky opening. A big drop here says nothing about the next one.
