Which games are running hot: z-scores for volume, win rate, average multiplier and 10x/50x hit rates against each game’s own 7-day baseline.
A heat score answers one question: is this game behaving unusually compared with its own recent history? We compute five z-scores per game — wagered volume, win rate, average multiplier, 10x hit rate and 50x hit rate — against that game’s own hourly baseline from the past seven days, then combine them into a 0 to 100 figure.
The comparison is always against the game itself, never against other games. A high-volatility slot with a 20% win rate is not "cold" because a low-volatility slot wins more often; it is cold only when it is winning less often than it normally does.
Every score carries a confidence label driven by sample size, plus a baseline quality flag. A game with a handful of bets in the window gets a low confidence tag no matter how extreme its numbers look, because one 5,000x on twelve spins is noise wearing a costume.
Fresh games and freshly restarted collectors show a neutral score until at least eight hourly buckets exist. That is intentional: it is better to show nothing than to show a rank built on two hours of data.
Nothing on this page predicts your next spin. Slot outcomes are independent, and a provably fair game re-seeds from a commitment that has no memory of the previous result. A hot score is a description of what has already happened.
Where it is genuinely useful: spotting unusual volume before it appears in a promotion, seeing which titles are actually being played rather than merchandised, and comparing a game’s observed behaviour against its theoretical RTP on our RTP prediction page.
No, and any site telling you otherwise is selling something. Each round is independent; the heat score describes past behaviour relative to a baseline, nothing more.
That is our neutral state — it means the baseline does not yet have enough hourly buckets for the comparison to mean anything. Give it time or widen the window.
One hour, 24 hours and seven days. Shorter windows react faster and are noisier; the seven-day view is the one to use when you want stability.
