Online slots guides: the reel, priced per spin

What 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.
