Learn the handful of TFT decisions that get you to top 4.
New players don’t lose because they picked the wrong comp — they lose because they roll on impulse, field too few units, and let their carry die. LineLab teaches the few durable habits that fix that, then lets you drill them against a live coach.
What you’ll learn
Know the real win condition and treat your health like a resource.
Field a full, well-positioned, well-itemized board every round.
Turn gold into compounding power instead of spending it on impulse.
Level on a schedule and roll in disciplined bursts.
Scout the other seven players and let it shape your plan.
Three ways to get better
Learn
Fourteen fundamentals, each a single rule you can use right now — with the common mistake it fixes. Start with the must-know six.
Read the fundamentals →Practice
The Arena is a playable auto-battler with a live coach that calls one move at a time — roll, level, save, or stabilize — so you drill the habits instead of reading about them.
Open the Arena →Check a spot
Stuck on a decision? The Solver reads any spot and gives you one move with a plain-English why — and the full expected-value math is one click away when you want it.
Try the Solver →How the coach works
The app reads your health, gold, level, and board strength for you — you never have to rate your own board.
Thousands of fast simulated games collapse into a single recommended action: roll, level, save, or stabilize.
Every call comes with a one-line reason tied to a fundamental, so the habit sticks. The numbers are there if you want them.
An independent learning tool
LineLab teaches universal TFT fundamentals using the game’s own vocabulary — gold, interest, levels, rolls, traits, augments. It uses no Riot Games assets, artwork, champion data, or live-client access, and is not affiliated with or endorsed by Riot. The Arena and Solver run on an original simulation model.
