Supply Chain Lab SCOPE 2 · DEMO
PLAY IN FOUR MINUTES

SCOPE 2: Price War

You run one shop in a five-tier supply chain. Three other shops compete with you for the same customers. Bots play every other seat, so you can play alone, right now.

Rounds 0 to 8. Each round you set a sealed price, then order stock that arrives next round. Watch for Black Friday.

Retailer 1 · Chain SC1

Customers want this round-
-On your shelf
-Your profit
-Sold last round

Your sealed price

$

Each unit costs you $8.00. Cheaper wins more customers but earns less per unit. The dearest shop only gets a small floor of customers.

Order from your wholesaler

It arrives next round. Every unit left on your shelf costs $0.32 a round and is written off at the end.

The market split

Bars show units each shop sold at its price. A shop with no stock sells nothing, whatever its price.

Your chain right now

Stock on hand at each tier. Everyone except you is a bot.

Watch the bullwhip

Orders swing more than sales as they travel upstream, and they arrive a round late.

GAME OVER

Your chain finished

-Your profit
-Your chain's score

What you just felt

Delay. Orders arrive a round late, so ordering to fill today's gap overshoots tomorrow.

Limited information. You saw only your own shop; upstream saw only your orders.

Price. Cheapest was not best, and no price sells stock you do not have.

How was it?

One tap, anonymous. Nothing else is recorded.

About this demo

The concept

A five-tier supply chain where nobody sees the whole picture, plus retailers competing on price for one market. The bullwhip effect emerges from delay and limited information.

How it works

The same verified engine as the SCOPE 2 class game. You play Retailer 1; bots play the other eleven seats. Nine rounds, with Black Friday in round 7.

Winning strategy

Price just below the dearest rival, order for the demand you expect rather than the demand you just saw, and finish with an empty shelf.
