Expansions
How often each expansion shows up in community games, and how much it actually moves the team win rate. The meta map further down groups every unique expansion combination by similarity, sized by how often that combo is played and colored by win rate.
How the community plays
Team size: how the community plays
How often each table size shows up in community games — solo runs, full crews of eight, and everything in between.
Team size: win rate
How well the community does at each table size. The Ancient Ones page breaks this down further into a per-AO heatmap.
The community, through time
Community win rate over time
The community's win rate, smoothed over a year so individual hot streaks don't bounce the line around. Dashed lines mark expansion release dates — the same events that reshuffle the rankings further down.
Expansion frequency vs. impact
Each dot is an expansion. Across the bottom: how much teams' win rate changes when this expansion is in the box (right = teams win more with it). Up the side: how often the community plays with it. Bubble size = total games. Top-right is a popular AND helpful expansion; top-left is popular but doesn't move the needle (or makes things harder).
Expansion-combination map
Every expansion combo with at least 5 logged games, arranged so similar combos sit close together. Bubble size = games played with that combo; color = how well teams do with it.
How investigator rankings shift across expansions
Each line is an investigator. The vertical axis is their rank (1 = best) inside each expansion era. Lines that cross each other mean the meta shifted between eras. Hover a line to isolate it; gaps appear where an investigator didn't have enough games in that era to rank.
How Ancient One rankings shift across expansions
Same idea, this time for Ancient Ones, ranked by win rate. Rank 1 is the AO the community beat most often in that era — the easiest — with the usual nudge so small samples don't dominate. Watch for AOs that climb or crash down the list as expansions reshape what's at the table.
Optional rules
The Optional Rules Lab
Does flipping a rules toggle actually change anything? Each bar shows the difference in win rate between games using that option and games not using it. The whiskers show the range of uncertainty — bars whose whiskers cross zero are too close to call from the data we have.
The `Prelude` option flag indicates use of optional Prelude rules; it is independent of the named prelude column.
Effect of Mythos modification
How the community fares with each Mythos modification setting.
