What the numbers mean
The current overall metric sits at 64, down slightly from a previous 65.9. Across our 26-week tracking window it has moved between a low of 60.4 and a high of 66.4 — a narrow band that signals a consistent, undramatic performer rather than a site trending sharply up or down. The recent dip from 65.9 to 64 is well within normal fluctuation.
The strongest driver is experience cleanliness: ad load is 0 and ad-quietness scored a perfect 100 in the Games category. Combine that with a signup level of 0 and a high free share (~85%) and you get a site that scores well on friction even where it scores modestly elsewhere.
The single tracked category is Games, ranked #34 of 38 — the low end of a crowded field. Catalog depth (50) and freshness (60) are middling, quality (64) is a relative bright spot, and trust (49) is the clearest drag on the overall index.
Confidence & data notes
Measured with higher confidence (85): library, popularity, trust and ad level — all derived from observable signals. These are the numbers to lean on.
Importantly, the trust score of 49 measures transparency and accountability signals — policy pages, contact/DMCA routes, domain history — not whether the site is safe. A middling trust figure means thin accountability signals, not a safety verdict.
What kind of content is on Jast USA?
Jast USA concentrates on porn games. That niche is the sole category highlighted for the platform, steering the entire product selection toward adult interactive titles. Shoppers who prefer games over standard video clips will recognize the focus immediately upon landing on the site.
Is Jast USA free?
Roughly 85 percent free access means Jast USA lets most visitors sample porn games without paying first. The experience stays relatively uncluttered thanks to low advertising. Because current subscription prices could not be verified, free browsing is the most reliable starting point described here.
Is Jast USA safe and legit?
From a consumer-guide view, Jast USA displays transparency signals like clear labeling and consistent presentation that support a legitimacy assessment. No outlet can certify absolute safety, so treat those signals as helpful clues only and complete your own due diligence before any purchase or registration.
