How We Rate Slots
Six sub-scores, each judged from what the provider publishes, averaged into the score you see.
Updated
Every slot score on this site is the plain average of six sub-scores, each from 0 to 10, shown with one decimal. A score appears only when all six parts are filled in; until then the review says "Not scored". The figures behind each part come from the provider - its game page, its game sheet or the rules screen inside its own demo - and each one carries the date we checked it.
Slot lists follow from that: scored slots first, highest score first, then the rest by how often Canadians search for each game, using Ahrefs data for Canada from October 2026. Lists are never ordered by what players played, because we have no such data.
The six parts and what each one looks at
- Gameplay: the layout, how wins are counted (paylines, ways, clusters or scatter pays) and how the base game works, from the provider's rules.
- Bonus features: free spins, multipliers, hold-and-win respins, jackpots and feature buys, as the provider describes them.
- RTP: the default return to player, with any lower versions the provider publishes. A low default scores low: Pirots 2, at 94.0%, scores well below the games at 96% and above.
- Volatility: whether the provider rates it, and on what scale. An unpublished rating earns nothing.
- Win potential: the published max win and how the provider words it. No published cap, no points.
- Mobile play: 7 when the provider's browser demo works or the provider states mobile or HTML5 play; otherwise 0.
One rule runs through all six: a missing figure is never rewarded. If a provider publishes none of RTP, volatility and max win, or if four or more of the six parts would score zero, too little is verifiable: the slot is not scored at all, and the review shows only the figures that are published.
Where the figures come from
The provider comes first. RTP, volatility, max win, bet range, layout and features come from the provider's own game page, its game sheet - Nolimit City, for one, publishes PDF sheets - or the rules inside its demo. When a live page blocks Canadian visitors or has changed, we use an archived copy and say so. Each figure on a slot review links to its source and shows the date checked.
Where a provider publishes several RTP versions, we list them all, because the casino picks which one runs and the game looks identical either way. Mental, for example, comes at 96.08% and 94.20%. Where a casino or another website disagrees with the provider, the provider wins. Bet ranges taken from a demo are marked as demo figures, sometimes in euros or play currency, because that is how the provider shows them.
Which casinos carry a slot is a separate question from its score. A slot review lists casinos whose own published provider list includes the game's studio, with a reminder to check the lobby, and marks a casino as having the game only when we saw it in that casino's lobby, with the date.
What a score is not
A slot score is not a prediction of what you will win, and it is not built from anyone's lucky or unlucky session. The current scores come from the published figures, not from play sessions: a few hundred spins say nothing reliable about a game whose free spins land once in 216 spins on average, as Nolimit City's sheet says of Mental, or whose cap hits once in millions. If we ever log demo sessions, the review will say how many spins, on which date, and that they were demo spins. We never claim real-money results.
A score also says nothing about whether a game suits your budget. A high volatility game can score well on win potential and still be the wrong choice for a small balance; the volatility guide explains how to read that side. Every slot keeps a house edge, whatever its score, and no score makes one game more likely to pay than another on your next spin. If you use the scores at all, use them to shortlist games whose published figures you like - a higher default RTP, a clear volatility rating, a stated max win - and then try the free demo before spending anything.
Our partner and the slot reviews
We have one partner casino, Neospin, and we earn a commission when a reader signs up there through our links. The partner has no say in any slot's score. On a slot review, the Neospin button appears only when we saw that game in Neospin's lobby, with the date of the sighting; otherwise the review points to other casinos' profiles, with no partner link. Neospin's own casino score is the one place where hands-on testing counts: our team tested it in October 2026, and how we rate casinos covers the casino method.
Visitors from Ontario see no partner buttons or offers anywhere on the site. All play is for adults: 19+, or 18+ in Alberta, Manitoba and Quebec. Spotted a figure that is wrong? Tell us and include the source; corrections are dated on the page they change. The same rules apply to every slot page, whether or not Neospin carries the game, and nothing on a slot review is written or approved by a casino or a provider.
Questions
Either not all six parts have been checked yet, or too little is published to judge: the provider gives none of RTP, volatility and max win, or four or more of the six parts would score zero. We would rather show no score than one built on guesses. The review still lists every figure the provider does publish, with its source.
The scores are built from the provider's published figures, not from play sessions, because a short session cannot reveal a game's RTP or volatility. Most reviews open the provider's free demo so you can try the game yourself. We never claim real-money results, and any demo session we log will be dated on the review.
No. Neospin, our one partner, has no input into any slot score. It appears on a slot review with a play button only when we saw the game in its lobby, and that sighting is dated. Visitors from Ontario never see the button or any offer.
Every figure on a slot review shows the date it was last checked, and each source is listed under References at the foot of the page. Any change to a review, from a corrected figure to a newly published RTP version, is dated in its "What changed" list, so you can see how fresh the page is.
