Where we are different
How our numbers are made
-
We keep the whole game.
We store all ten players of every game and every item they bought, with the minute. That lets us judge a buy at the moment it was made.
-
We compare like with like.
A plain item win rate mostly shows who was already winning. We compare players who bought the item with players in the same spot who did not, at the same point in the game.
-
A new patch builds on the last one.
Our numbers come from our own crawl. Early in a patch the models still lean on the previous patch, and every six hours they retrain with more games from the new one.
-
The site and the app agree.
The app and this site ask the same server, so they show the same numbers.
In your game
Hold Tab. Your next item is there.
The Build panel has two sources. Matchup is made for this game, against their team. Sleeper is a rare build that wins more than the usual one. Click the word on the panel or press Ctrl+Shift+B to switch.
How Matchup picks the item
-
Reads the enemy team
Physical or magic damage, healing, shields, crowd control, and who is ahead.
-
Finds games like yours
Your champion and role, at this point in the game, against a similar team.
-
Ranks what won for them
Every item you can buy, by how much better those players did after buying it.
-
Walks you to the shop
The item, its parts in order, the gold still missing. When the enemy team changes, so does the recommendation.
In champion select
Your best pick before you lock in
The app reads the draft as it happens and scores every champion you could lock, using both teams, both ban lists, your lane and your history.
Your team
In the score

Bans
Teammates without the app get a link in chat with the same picks and bans.
Solve
Solve does not care what people buy
Solve ignores win rates and popular builds. It works from your stats and the five enemies' items, armour and magic resist, and updates as they buy.
Off by default. One switch in Settings. Hold Tab and click the arrows to see its top 3. Short on gold? It shows the part to buy now.
