Challenge
On-stage lucky draws need to be both exciting and beyond suspicion
Traditional lucky-draw shows are often questioned for transparency, hard to keep in sync between the stage screen and audience devices, and give thousands of attendees no way to participate directly from their own phones.
Solution
A realtime draw platform, transparent by design
We built Lucky Draw — Code4Change's own SaaS product — with a fraud-resistant draw mechanism, realtime sync between the main screen and audience devices, running reliably at tens-of-thousands-of-attendees scale.
Outcome
One product, running across many events
Lucky Draw is now Code4Change's live, operating SaaS product, powering large-scale audience-participation moments at events across Vietnam.
