A one-week prototype that became a $200M game — the exact prototype-test-scale system that turns simple mechanics into money printers.
100M+ downloads · $7.9M in-app purchases in Q1 2025 alone · 160% ROAS at day 120
"Nine out of ten prototypes get dropped." The winners aren't luck — they clear hard numbers first: CPI under $2, ~30 minutes of play, 30–40% day-one retention, before a dollar of scale spend.

Mob Control is a Voodoo game with a mechanic simple enough to explain in a sentence: swipe to route a stream of multiplying stickmen through gates and overwhelm the enemy. MikeRoxy's breakdown reports the outcome in hard numbers — over 100 million downloads and more than $200 million in revenue, with $7.9 million in in-app purchases in Q1 2025 alone. The origin is the lesson. The first version of Mob Control was built in one week, in 2021, and shipped as a prototype purely to test whether the mechanic was fun. The video is explicit that this is a repeatable system, not a fluke: "Roll a dice — not luck. It's a repeatable system." What makes this a Scale Reference rather than a copy-this-now case is what came after the prototype. Three months post-launch, a dedicated team of four took over with a specific mission: convert Mob Control from a hyper-casual game (revenue almost entirely from ads) into a hybrid-casual game (revenue driven by in-app purchases). That transition took nine months of development and added coin systems, base building, and other retention mechanics. Our read: the value here isn't 'make a stickman game.' It's the industrialised pipeline — prototype in days, kill fast on numbers, and only pour money into the tiny fraction that clears the benchmarks. That system is what an indie can actually learn from, even without Voodoo's balance sheet.
The first players were bought, not found. There is no launch audience for a swipe-and-multiply stickman game: no search demand, no community, no word of mouth.

Data credibility: Third-party analytical breakdown by YouTube channel MikeRoxy of a publicly documented Voodoo title. Headline figures (100M+ downloads, $200M+ revenue, $7.9M in Q1 2025 in-app purchases, 160% ROAS at day 120, one-week initial build, nine-month hybrid-casual transition by a team of four) are presented as researched/industry data and align with widely reported figures on this game and the hyper-casual market; graded Verified given the third-party-data framing, though specific internal numbers were not independently re-audited here. Benchmark targets (CPI under $2, ~30 min play, 30–40% day-one retention) are stated as general publisher benchmarks that vary by genre.
In 2021 a hyper-casual title's first dollar came from an ad impression, not a purchase. What Mob Control sold at launch was attention, served as interstitials and rewarded video to players the publisher had just bought, priced not by the developer but by whatever eCPM the ad networks were paying that week.
The flywheel here is arithmetic, and it starts turning at one number: 160% return on ad spend at day 120.
The pipeline is engineered to make the no-feedback stretch short. A one-week prototype plus a few hundred dollars of installs returns a verdict in days, and the verdict is numeric rather than emotional: CPI, play time, day-one retention.
