First person
Warehouse floor
Walk the aisles, pick and put away against the clock, and feel why slotting and travel time drive cost.
Supply chain, played
Run real supply chain decisions. Build a skill profile that proves it.
You take contracts from companies like a garden-tools retailer, a pharma group and a brake-pad maker. You make the calls under real constraints, the engine scores them, and every decision lands on your skill tree.

Ways to play
Different contracts, different ways to play
Some people think best on a map, some in a spreadsheet, some on the warehouse floor. Every format trains specific paths on your tree.
Isometric
Factory floor
Run shifts on a living factory: find the bottleneck, protect OEE, and watch WIP pile up when you guess wrong.
2D map
Network map
Place plants and DCs, choose lanes and modes, and run months of cost, service and carbon results.
City builder
Company sim
Run a whole company for several quarters and balance service, cost, cash, risk and carbon.
Third person
3D yard
Load trucks, move containers through a port yard and audit a supplier's floor in 3D.
2D board
Order desk
Promise scarce stock across key accounts without breaking available-to-promise.
Text
Inbox and negotiation
Answer the director, negotiate with a supplier who has their own walk-away price, and fix master data in a live ERP terminal.
Chain sim
Beer chain
Order for the retailer, wholesaler, distributor and factory. Only the shop sees real demand, and a two-week delay turns a small change into a bullwhip.
Grid builder
Computer factory
Lay out drills, fabs and belts from ore to a finished PC. The slowest machine sets the pace, and work in progress piles up when the line is unbalanced.
Top-down
Delivery routes
Drive the van against delivery windows, then grow a fleet and assign each district. Capacity, speed and the route you choose decide what arrives on time.
The skill tree
One profile, built from every decision
01Foundations
Lead time, inventory, demand and supply, and the cost-cash-service trade-off. Everyone starts here.
02Five core paths
Planning & Inventory, Procurement, Manufacturing, Logistics, Customer & Order Management.
03Seven capabilities
Analytics, Finance, Quality, Risk, Digital, Sustainability and Leadership run across every path.
04Orchestration
The advanced path. It only unlocks when you have breadth across the core paths.
XP shows how much you have practiced. Mastery shows how well you have demonstrated it: easy contracts are capped, and mastery needs several different contracts before it can rise. Click a node below. This is a sample profile.
How a contract works
Briefing, decisions, debrief
-
1
Take a contract
The board recommends your next contract from your weakest skills, for example "your capacity-planning mastery lags your other Planning skills".
-
2
Decide under constraints
A supplier is three weeks late, you hold twelve days of stock and your largest customer has a penalty clause. There is no single right answer, only trade-offs.
-
3
See what it built
The debrief explains the trade-off and shows XP and mastery moving on the paths your decisions touched.
Skill Passport
"I completed 43 courses" says little. Your passport shows what you can do.
Premium players publish a public Skill Passport: XP level and mastery on every path, your strongest capabilities and the hardest contracts you delivered, linked to a verifiable certificate. Share it on LinkedIn or attach it to a CV.

Questions
Before you start
Who is it for?
Supply chain students who want practice beyond theory, and professionals who want to grow into a new function or prepare for a promotion or interview.
Is this a course?
No. There are no videos to sit through. Each contract is a short simulation where you make decisions and the engine scores them. Short briefings and debriefs explain the concepts as you go.
How is mastery different from XP?
XP grows every time you play. Mastery only grows when you perform well on contracts that are hard enough to prove it, across several different contracts. Replaying an easy contract a hundred times will not make you a specialist.
Do I need to install anything?
No. Everything runs in the browser. The 3D and first-person contracts work best on a laptop or desktop; most others also work on a phone.
Can I cancel Premium?
Yes, any time from your account page. Everything you earned stays on your profile.
