Music & Rock slots.

A slot is classified into the music & rock bucket when its published title or studio description matches the theme keyword set at build time — no proprietary tags, no manual curation. 38 titles land here today (0.7% of 5 350 indexed releases). Refreshed September 2026.

Mixed catalog around the industry baseline — some CLAIM-tier titles inside, but the theme average sits at typical variance and typical RTP. Filter by RTP band below for the wagering-friendly slice. Verdict at build time: NEUTRAL. The mechanical reason: wagering-through is a race between your bankroll and the sample cost of the paytable. Theme is cosmetic; the axes that actually matter are RTP (mean edge per €100 wagered) and volatility (standard deviation of that edge). This theme averages 95.74% RTP at a medium-vol dominant, hence the NEUTRAL bracket. Filter by RTP band above for the wagering-friendly slice.

Each title carries a studio-published volatility rating on its info panel — we normalise to a five-band scale (low → high) using each studio’s certification test. The dominant volatility for music & rock slots is medium, and the theme-wide average sits at 3.50 on the 1–5 index. See the volatility & variance guide for the distribution math and the medium-vol hub for the full band catalog.

The theme is cosmetic — the bankroll floor is a function of volatility, not aesthetic. Dominant volatility here is medium; a medium-vol session typically needs a bankroll of 300–500× base bet to keep ruin probability under 5% through a wagering multiplier.

Theme is one axis, RTP is another — they compose freely. Cross this hub with highest-RTP (≥ 97.5%) for the calmest wagering path inside the music & rock bucket, or with high-RTP (≥ 96%) for the widest baseline shortlist. The RTP-band breakdown above shows exactly how many music & rock titles fall into each bracket at the current build.

Provider JSON-LD didn’t yield useful genre metadata across the catalog, so themes are keyword-detected from title and description at build time using a curated regex per theme. That’s the reason the music & rock hub can be inspected line-by-line: no black-box classifier, no scraping heuristic — the keyword set is in src/lib/themes.ts in the repo. New themes and keyword tweaks land alongside catalog refreshes.
