Online slots guides: the reel, priced per spin
A slot is the most measurable game in the building: RTP is published, volatility is describable, and the price per hour is arithmetic. This series does that arithmetic across the whole slots market.
The scorecards come first — every operator below is scored with slot-play value in mind, and the ranking note under the cards explains the order.

Open the offerWhat the slots series covers
The series covers the slots market the way an accountant would: what a spin costs, what the game returns, and how the two interact over an hour. The main online-slots guide covers the method (RTP, volatility, price per hour); the top-10 and top-20 pages apply it to the market's headline games; the new-slots page sets up a triage for launches; and the named guides — Big Bass, Pragmatic's catalogue, bitcoin-side slots — price the specific titles players actually search for.
Bonus terms ride on slot play more than any other game, so the series crosses into the offers side: free-spin packs tied to named slots, wagering contributions where slots count fully, and the max-bet rules that void winnings when breached. The free-spins hub carries the offer pricing; this hub carries the game pricing — and the two meet in every guide's calculator.

How the series prices a spin
Three numbers do the work: stake, RTP, spins per hour. Price per hour is stake times spins minus the RTP share — the guides run it for the market's common stakes (10p to £2) and show why volatility, not RTP, decides whether an hour is survivable. Session-ruin arithmetic (the chance a bankroll lasts the hour at a given volatility) appears in every guide with the same prefilled calculator, so the reader can swap in their own numbers.
The series is deliberately cold about themes and features: a bonus round is a distribution, not an event, and a dropping-odds mechanic is priced the same as any other. What the guides refuse to do is rank slots by vibes — every recommendation in the hub traces to the three numbers or it is not made.
