Anyone who has sat through a casino jackpot draw run off a whiteboard knows the problem: a name is read out, someone in the crowd disputes it, a phone is already filming, and the whole room loses ten minutes to an argument nobody can settle because there's no record to point to. It's the kind of moment that turns a promotional draw night into a headache for management.
A Dar es Salaam-built platform called Event OS, from local company Ellertek Solutions (ellertek.co.tz), is aimed squarely at that problem — and it's worth knowing about if you run, manage, or simply enjoy draw nights at casinos in the city.
What Event OS Actually Does
"Event OS runs from a single Windows laptop and turns every screen at a venue — TVs, projectors, phones — into a synchronized display, updating everything in under a second," said Micah Edgar, CEO of Ellertek Solutions. "Critically, it's built to run with no internet connection at all once activated, operating on the venue's own Wi-Fi or a self-contained hotspot."
For a casino draw night specifically, that means the draw schedule and player list load into the system in advance, the jackpot total displays live across every screen in the room, and when a winner is picked, the reveal fills every screen simultaneously with the same result — rather than one person shouting a name from a stage.
Edgar also said the system is power-cut proof: if electricity drops mid-event, the platform and every connected screen resume exactly where they left off once power returns — no manual restart needed.
The detail that matters most for disputes: every action in the system sits in what Ellertek calls a tamper-evident audit trail. Instead of "he said, she said" about who was drawn, there's a timestamped record of the draw itself.
Built for Tanzania's Actual Conditions
Given how often power and connectivity can be unpredictable at venues here, offline-first isn't a nice-to-have, it's the point. The interface and voice announcements also run in both Kiswahili and English, switchable live — a detail that a lot of casino software from abroad simply doesn't offer.
How It's Priced
Ellertek Solutions sells Event OS in modules, billed monthly, quarterly, or annually. The module built specifically for this use case is called Jackpot & Draw — a live jackpot counter, scheduled draws, and the synchronized winner reveal. For casinos, it's bundled with the Digital Signage & Promo module (for rotating offers and notices between draws) as the "Casino Draw Night" package, at TZS 525,000 per month, or TZS 5,355,000 per year if paid annually — a 15% discount over paying monthly.
Payment runs through M-Pesa, Tigo Pesa, Airtel Money, or bank transfer, and licenses simply expire at the end of the period rather than auto-renewing — there's no ongoing contract to cancel.
Already Running at Princess Casino Dar es Salaam
This isn't hypothetical for the city: Princess Casino Dar es Salaam has already begun using Event OS for its draw nights. It's an early, local sign of exactly the shift this piece is describing — a Tanzanian casino moving its jackpot draws onto a system built for tamper-evident results and synced screens, rather than a whiteboard and a microphone.
Not Just for Casinos
The same underlying platform is being pitched to weddings, with a separate "Wedding & MC Pack" that bundles a countdown timer, live programme, winner announcements (useful for things like bouquet tosses), live guest voting, and a guest photo wall that puts phone photos up on the big screen during the reception. "We welcome everyone with a taste for excellence in the entertainment and event management industry to embrace this new way of managing their events," Edgar said, naming MCs, casino owners, corporates, and event organizers as exactly who Ellertek Solutions built the platform for.
Worth a Look
Ellertek Solutions offers a 3-day free trial with every module unlocked, so a venue can test it on a real event before paying anything. For casino management weighing whether a dispute-proof, offline-capable draw system is worth the monthly cost, that's a reasonably low-risk way to find out.
