About RerollHQ
An honest, transparent look at where these numbers come from — and where they don't.

Sample sizes are shown live and update as the collector runs. Each match contributes 8 player boards, so counts are reported as matches. Ranks are disjoint bands (iron → challenger) you can combine freely; a selection is treated as "ready" once its merged sample clears about 125matches — below that the page stays visible with an honest "collecting data" note.
Where the data comes from
Every statistic on RerollHQ is computed from real, finished Teamfight Tactics games pulled from the official Riot Games API. Ranked is the default view; other queues (Normal, Double Up, and events) appear as their own tabs once enough games are collected. We do not use simulations, hand-authored tier lists, or third-party scrapes.
How matches are sampled
Collection is focused on the top of the ranked ladder. We continuously discover high-rated players, then walk their recent ranked match history, de-duplicating games so each match counts once. Placements, units, items, and traits are read directly from each match's participant records.
How the numbers are computed
For each patch, mode, and rank band we aggregate every observed unit, item, trait, comp, and full build, tracking games played, average placement, top-4 rate, and win rate. Rows below a minimum sample threshold are hidden from default views; rows just above it carry a "low sample" tag so you can weigh them accordingly. Average placement is the headline metric throughout — lower is better.
Patch & update cadence
Stats are scoped to the current live patch (17.6, TFTSet17). Published pages are cached and revalidated every 15 minutes, so figures stay fresh while keeping load on the data source minimal.
A note on honesty
This project is young and its samples are still growing. Rather than inflate confidence, we surface sample sizes everywhere and frame small-sample comps as "emerging." As the dataset grows, the numbers you see will only get sharper.
