Objective: Navigate 3 real-world decision points in launching a discount flash sale, choosing between honest and manufactured urgency at each stage, and see how each choice compounds into either a defensible campaign or a legal/trust liability, without spending a rupee or a dollar.

You're the growth marketing lead at HelloFresh, running a flash-sale discount for new subscribers with an $18,000 campaign budget. Legal, design, and your own conversion targets are all pulling in different directions over the next 3 days.

Make 3 sequential calls: the launch copy, the stock-counter widget, and (if you chose poorly) how to respond when legal flags the campaign. This can't be practiced live for free, a real fake-urgency rollout risks real fines and real brand damage, so you run it as a scored simulation instead.

The process

Simulation

Day 0: Writing the Launch Copy

0 hours

Your team has two subject-line drafts on the table for the new-subscriber discount email, and needs a decision by end of day to hit the print/email schedule.

Sample output

Draft A: 'Price goes up Friday, our new-customer rate changes then.'
Draft B: 'Sale ends in 23:59:59', a JS countdown that resets to 23:59:59 every time the page loads.
Draft C: 'Ends this week', vague but not fabricated.

Spend to date:$0

Budget remaining:$18,000 campaign budget, untouched

Which launch copy do you ship?

Final deliverable

A written decision log across all 3 stages: your choice, the outcome, and a one-sentence justification tied to the lesson's ethics checklist for each.

Sample output

Swiggy flash-sale simulation, decision log

Stage 1 (launch copy): Chose real-deadline anchor. Justification: rate change is a genuine event, verifiable if a customer asks.
Stage 2 (stock counter): Chose live-inventory counter. Justification: matches Stage 1's honesty and still captures most of the conversion lift.
Result: campaign completed without a legal flag, final conversion 4.2% vs 2.4% baseline, refund rate unchanged.

Success criteria

You're done when you can:

Completes all reachable stages with a documented decision at each
Written justification cites the specific lesson section, not just 'felt right'
Final log distinguishes what changed (or didn't) between the optimal and costly path
