How it works
- 1
Name a goal
In your own words: “times tables”, “SAT prep”, “Python for analysts”. Even a single word works.

Get a map
Lumex lays out a path of locations for your level — from a warm-up to the final boss.

Win with answers
Every location is a battle: a right answer hits the guardian, a mistake hits you. Difficulty adapts.
