Junction
Overview
What is Junction?
A mobile practice product that turns journey critique into a game loop — for designers, PMs, and anyone who thinks in flows, not slides.
Designers and PMs train endlessly on screens. Industry still under-trains journeys: recovery paths, decision forks, terminal success, and the ugly middle where payment fails or a rider cancels.
The core loop is simple: Brief → place nodes → wire → simulate → score → retry. Each level gives you a realistic product scenario. You build the journey on a canvas, run a virtual user through it, and get feedback like a design review — not a mysterious number.
Junction is not a Figma replacement, a WCAG certification tool, or a substitute for research. It grades journey shape and scenario fit — and states that limit openly.
How it works
Four steps. One honest score.
Every mode uses the same engine. Modes change the constraint — depth, speed, competition — not the rules of judgment.
Step 01
Read the brief
Each level opens with a realistic scenario: checkout recovery, KYC onboarding, OTP verification, SaaS permissions, or a timed Blitz prompt. You know the job before you wire a single node.
Step 02 — 03
Build & simulate
Drop screens, actions, decisions, and errors. Connect paths the way a real user would travel. Hit Simulate and watch branches, dead ends, and recovery paths play out before anything ships.
Step 04
Score & retry
Results break down six UX metrics with actionable feedback. Shortcuts that skip key steps stay in the failure band — even if they reach Complete. Retry until your journey earns mastery.

Game modes
Seven ways to practice
~210 campaign levels across six worlds. Same scoring engine everywhere — no pay-to-win advantages.
Campaign
Level-by-level product scenarios across Ecommerce, Food Delivery, Travel, Fintech, SaaS, and Inclusive Design. Real patterns: checkout, KYC, OTP, permissions.
Blitz
60-second build-from-scratch sprints with 50+ unique scenarios. Read fast, wire faster, simulate under pressure.
Online Blitz
Race another player in real time. Same scenario, same timer, Elo-style rating. No chat — just craft.
Daily Challenge
One fresh puzzle every day. Build streaks, track activity on a calendar, and export your grid as a shareable PNG.
Vs CPU
Practice against an AI opponent when you want competition without matchmaking.
Sandbox
Free experimentation with no timer. Sketch any flow and test your instincts.
Learn
22 guided lessons across three tracks — flow grammar, Figma handoff, and UX audit thinking. Intro free; full curriculum with Pro.
Learn track
Curriculum, not just levels
Lessons include readings, practice puzzles, and quizzes. Learn what a user flow is, how to read a diagram, and when recovery paths matter — alongside hands-on play.
Scoring
Six metrics. One trustworthy judge.
Early versions treated “wires reach Complete” as mastery — broken shortcuts looked like wins. Junction rebuilt judgment as a local, deterministic quality engine: grammar, scenario milestones, intent. Results and UX Flow Audit agree within ±2 points.
Language models may polish coaching copy — but they never set the grade.
Vision
Why Junction exists
Critique of user journeys is slow, subjective, and hard to repeat. Junction makes it practiceable — fast enough to retry in minutes, strict enough that false completions cannot masquerade as mastery.
Industry trains screens. Junction trains journeys — recovery, decisions, terminal success, and everything in between.
- Critique over candyScores below 50 use failure treatment so “Flow complete” never reads as a win for a broken path.
- One judgeEvery mode calls the same local engine. No parallel AI score inventing numbers.
- Job, not wire IDMilestones resolve by role and alias — creative wiring that completes the job can score high.
- Mastery monetizationNo ads. No lives. No energy bars. Pro unlocks worlds and tools — not score advantages.
- Accessibility is contentInclusive Design is a playable world. Reduce Motion, high contrast, and color-vision themes are first-class settings.
