LoL Draft Simulator with AI win prediction
Simulate any League of Legends draft and see who it favors. A neural network trained on millions of ranked games predicts the win rate and ranks every champion for the open slots, updated for patch 16.21.
How the draft simulator works
- Step 1
Pick both teams
Click champions into any of the ten slots, in any order. Leave slots empty to simulate a draft in progress.
- Step 2
Set your elo and patch
Predictions depend on rank, so choose yours, from Silver to Master+, or the pro play model.
- Step 3
Read the prediction
See the predicted win rate, each champion's impact on it, and how the odds change with game length.
- Step 4
Find the best pick
Open suggestions on any empty slot to rank every champion for this exact draft, with runes and an item build.
The best pick for the draft you simulated
Champion suggestions rank every champion against both teams, not just lane matchups. Star the champions you play to see only your pool, or switch to the counterpick-adjusted mode to find picks that stay strong when you're picking blind.

Draft simulator FAQ
What is a LoL draft simulator?
A draft simulator lets you fill in champion picks for both teams outside of champion select, to practice drafting or test team compositions. LoLDraftAI adds an AI model on top: every simulated draft gets a predicted win rate and pick suggestions.
How is this different from a pick-and-ban practice tool?
Pick-and-ban tools reproduce the champion select interface for practice with friends or teams. LoLDraftAI focuses on analysis: it tells you which side the draft favors, why, and what to pick next, using a neural network trained on millions of ranked games.
Is the draft simulator free?
Yes. You can simulate drafts for free with a limited champion pool. A subscription unlocks every champion and all elo brackets.
Can I use it during a real champion select?
Yes. The Windows desktop app connects to your League client, fills in the draft live as champions are picked, and can apply recommended runes, summoner spells and item sets in one click.
How accurate are the predictions?
The model predicts game outcomes from draft alone with 56.7% accuracy, and it is well calibrated: drafts predicted at 55% really win about 55% of the time. Draft is one factor among many, so even a bad draft is very winnable.
