How NineCasino Achieved 105% ROI in Brazil

Overview

In Brazil’s fast-moving gambling market, the Syndicate media buying team set out to maximize returns on the NineCasino offer from Chilli Partners. They built a precise funnel using localized assets, Pix payment integration, and Android-only targeting. With just five weeks of testing and agile budget shifts, they delivered 57,294 app installs, 26,349 new registrations, and 3,367 first-time deposits (FTDs), driving €101,010 revenue against €49,273 spend for a 105% ROI and €51,736 net profit.

Campaign Goals

The primary aim was simple: turn small daily budgets into a sustainable profit stream. The team focused on first-deposit actions (FTDs) paid at €30 each. They set targets on reducing cost per install (CPI) under €1 and CPE (cost per registration) under €2, while maintaining high quality traffic to boost lifetime value.

Approach

Step 1: Offer & Payment Selection

Syndicate chose NineCasino for its full Portuguese localization and Pix deposits, used by 99% of Brazilians. Highlighting Pix icons in creatives raised trust and conversion. They picked Fortune Tiger—a slot trending among Brazilian players—to feature in video and static ads.

Step 2: Creative & Landing

Both motion videos and images showcased big wins, genuine reactions, and cash-out visuals. The team launched 2–5 ad sets per campaign, each with small budgets, and warmed up new fan pages through in-house farming. Manual targeting by age, gender, and OS improved quality before scaling.

Step 3: Tracking & Scaling

Using Octo Browser anti-detect, private proxies, and high-limit agency accounts, they kept operations smooth. Keitaro plus a custom analytics platform tracked installs, registrations, and FTDs. Once profitable, they duplicated winning ad sets and increased budgets, keeping CPL and CPI under control with auto-rules.

Results

Over a month, the campaign generated 57,294 installs at €0.86 CPI, 26,349 registrations at €1.87 CPA, and 3,367 deposits at €14.63 per FTD. Total revenue hit €101,010 against €49,273 spend, netting €51,736 and a 105% ROI on the top offer.

Lessons Learned

Localizing payment methods, using slot-focused creatives, and beginning with manual targeting proved critical. Controlled scaling through ad-set duplication kept CPI stable. A custom tracker allowed quick budget shifts and kept ROI high even at volume.
