Matchups
Every matchupHow to read this
Jax’s win rate against each champion picked into it in the lane opposite: its hardest matchups, then its easiest. The small number is the matchup’s own effect on Jax, the part not explained by either champion’s strength.
Hardest for Jax
Lane leads and team bans
What Jax’s team bans
Champions a team bans more often when it has Jax than the other team does in the same games (315,509 games). The other team banned before Jax was picked, so the gap is the ban spent because Jax was coming — a sign players see these as counters. Riot does not say which player cast a ban, so this is the team’s choice.

These numbers describe, they do not prove. Each rate is Jax’s record when its player chose that option, pulled toward Jax’s own rate by 100 games of prior so a small sample cannot look like a discovery. An uncommon page often wins more because experts run it, and they would win on any page, so only a choice taken in at least 10% of games can be recommended, and spells and keystones are ranked by how the SAME players do with them against the usual choice, not by the raw rate; rarer ones are listed with their numbers and labeled. The build line (opening buy, the two key items in the order they are finished, boots or the support upgrade) is advice in the same sense: how Jax does when built that way.
The learning curve
Champion pool
On a first game Jax wins 47.4%; in the hands of players with the most mastery on it, 51.7%. That gap ranks it 109 of 173 for how much practice pays. It crosses 50% at about 110K mastery points.
Pro play
On the pro tier list
Jax in the major leagues and international events this season, across 3,434 games: its record, how often it is picked or banned, whether it is taken blind or saved as a counter, its lane at 15 minutes, and the best pro on it.

How much knowing Jax pays
Players on their Mastery band win 4.3 points more on Jax than first-timers do: #109 of 173 champions for how much mastery pays.
At 300k+ mastery points, Jax players win 51.7%: #122 of 173 champions for where mastery ends up. The curve is still rising there: its fitted ceiling of about 53.0% lies beyond the data and is an estimate, not a measurement.
JaxDots are the six mastery bands, placed at their mastery points. The line is the best-fitting curve that rises and levels off.
This is not a promise about your next game. Players do not reach a mastery band in a random order, and a champion someone loses on tends to get dropped before it reaches the high bands — so the right-hand side of every curve is partly survivors, not only practice.
