Multiplier Gates Did Not Start With Last War

The gate-choosing ad is everywhere in 2026: squads multiply, players scream at the screen, installs follow. But the mechanic's story runs decades deeper than any one 4X launch - and the delivery data now points somewhere few strategy teams are looking.

Data scope

This piece mixes two kinds of evidence. Historical and industry facts (the gate-runner wave, Last War's scale and pull-back) come from published sources and are stated at magnitude only. Delivery figures - creatives, ad plans, market and network coverage, estimated exposure - come from CreativeScope and cover October 5 to November 4, 2026 unless stated as a trailing-180-day figure. They are observations of tracked advertising activity for two titles, Mob Control (Voodoo) and Last War: Survival Game (FunFly PTE. LTD.), not statements about either company's budget or results.

An ad plan is one buying configuration: a channel, a set of target markets and a language. It measures delivery structure, not money. The practice these numbers describe is user acquisition, often shortened to UA by practitioners - the paid, install-driving side of growing a mobile game.

Where the doors actually came from

The honest starting point is less romantic than the version usually retold. Multiplier gates are not a rediscovery of some older mechanic; they are a specific design solution that appeared around 2021 and spread because it solved a problem every runner-shaped game had. A lane with a crowd in it has one question - how big will my crowd get - and gates let the designer answer that question every two seconds with a visible number, without building a level around it.

That is the whole mechanic. A door carries a value, the crowd walks through, the crowd changes size. What separates it from older uses of numbers in games is that this number is not a key you look up once; it is a price the door charges you in public, over and over, while you watch. What the 2020s added was not arithmetic but an arrangement of arithmetic a player can evaluate in under a second, repeatedly, with something on the far side of the door still trying to kill them.

The gate-runner wave, 2021-2022

Between 2021 and 2022 that solution became a genre. Hyper-casual titles such as Crowd City, Join Clash and Count Masters built entire games out of the choice: a crowd runs down a lane, gates offer to multiply, add or divide it, and each pick reshapes the next ten seconds. Liftoff's hybrid-casual analysis described Mob Control's multiplier gates as "a trending hyper-casual mechanic"; ad-network research at the time found gate runners occupying three of the top ten US free-game slots in 2022, with half a billion combined installs across the leading three.

Mob Control, released May 2021 by Voodoo, pushed the format past the runner. It kept the gates and the crowd, added a cannon you aim at gates and at enemy stacks, and wrapped both in a collect-and-upgrade meta. The result is a game whose core verb - send your crowd through the right door - is legible in a single glance. That legibility is exactly what an ad needs, which is why gate footage became ad footage even for games that are not gate games at all.

Last War: the gate becomes a front end

The step that turned a mechanic into a formula came from the strategy category. Last War: Survival, published through FunFly (the studio behind Top War) with a global launch in August 2023, ran ads built almost entirely from a gate-runner: pick the door, dodge the wrong one, survive the zombie wave. The real game is a 4X base builder. The runner exists in the product as a side mode, which placed the ads in a gray zone critics have documented at length - and the volume did the arguing for the other side.

Third-party estimates published in July 2026 put the title at roughly 190 million lifetime installs and about $3.5 billion in net revenue - on the order of $18 per install, where most strategy titles measure that figure in low single digits. A late-2024 campaign fronted by the actor who plays Homelander in The Boys leaned directly into the joke that the ad game had become real. The formula spread fast: door-runner ads in front of 4X products became the category's default acquisition front end through 2024 and 2025.

Three gate creatives, watchable in full

The three creatives below are Mob Control videos active in the current window, embedded in full and playable in place. Two are Google-delivery portrait cuts; the third runs on TikTok. Platform, dates and estimated exposure are CreativeScope metadata; the scene descriptions that follow each file are observations of the videos themselves, and the timecodes refer to the players above them.

One pattern spans all four spotlight files: no fake gameplay, and a closing card built as a store search box rather than an install button - Mob Control's three gate videos and Last War's fiancée cut end the same way. Mob Control's cuts add no live actor; its copy does the credibility work instead, in an AdMob image creative running since late 2025 that carries the line "The game looks exactly like the ads" beside "From one to thousands" - a pitch written for an audience trained, by two years of gate ads for other games, to assume the ad is lying.

Last War puts a person on screen and says the joke out loud. The search-box close, on both accounts, asks the viewer to search the name, which keeps the install inside a store session the advertiser does not have to pay an attribution fee for.

Where the format stands in late 2026

The delivery ledger now tells an inversion story. Over the trailing 180 days, CreativeScope tracks 9,740 creatives and 20,595 ad plans for Mob Control against 116 creatives and 431 plans for Last War: Survival Game. In the last 30 days the gap holds: 3,768 creatives and 6,856 plans for Mob Control against 19 and 33 for Last War. On tracked plan counts that is a factor of roughly 48; on creatives, 84.

Last War's thin footprint matches what industry reporting described through 2026: monthly installs down by more than 80% from their early-year peak while revenue held, and media buying throttled to a fraction of its 2024 cadence once the title shifted from buying new users to working the base it had. What the tracked sample still buys, though, is the same format: the window's highest-exposure Last War video is a gate-runner with a live actor arguing about the "FAKE Game" (spotlighted above), and the runner is also the body line of its top AdMob cut ("Crowd Clash: Run Master").

The direction of the remaining buying is also legible. The current 33 plans all sit on Facebook and Instagram, and across the trailing 180 days the largest single-market blocks are the Czech Republic (112 plans, 90 exclusive), Singapore and Indonesia - not the United States, which covers 43 plans. In the tracked sample the recent plans open and close within a day or two, with per-plan estimated exposure in the low thousands; small, fast, Meta-weighted buying aimed at mid-cost markets is what a throttled campaign looks like in plan data.

Mob Control's numbers need the opposite caution. Twenty thousand plans is what Voodoo's programmatic template produces when it runs at full width: the same creative families recycled across market-language combinations, with France, Germany, Turkey and Spain at the top of the market list alongside the United States.

The network spread is just as wide. Facebook, Instagram, Audience Network and Threads each cover roughly 44% of the month's plans, and all fourteen tracked networks carry some share. The figure that argues quality rather than volume is reinvestment: 2,094 creatives returned to delivery after a pause across the trailing 180 days, and teams rarely re-open spending on creatives that did not earn their keep the first time.

What this history can and cannot tell you

The reading in one sentence: the gate ad earned its place by turning a number into a three-second decision, Last War industrialized it as a front end for a different genre, and in late 2026 the biggest gate advertiser is the game that originated the mechanic - buying at a scale its imitators have largely exited.

Alternative explanations deserve their own space. Mob Control's plan dominance may say more about Voodoo's always-on programmatic template than about the creative's pull; the exposure figures are cumulative since each creative's first-seen date and therefore favor incumbents; and Last War's small tracked footprint could partly reflect coverage limits in the tracked sample rather than spend alone, though it lines up with independent reporting of a deliberate pull-back. None of these caveats changes the structural point: the format's center of gravity has moved back to its originator.

The boundaries hold regardless. Coverage of a market or network shows where plans pointed, never what they returned; estimated exposure is not a platform-measured impression count; and nothing in plan counts, reinvestment rates or exposure estimates supports conclusions about cost per install, return on ad spend, or player preference. External scale figures (installs, revenue) are third-party estimates quoted at magnitude and are not mixed into the CreativeScope counts.

Frequently asked

What are multiplier gates?

The doors in a running crowd that carry a number - ×2, +50, ÷3 - and change the size of the crowd that walks through. Ad-network research has described them as a trending hyper-casual mechanic, and the games built on them are often called gate runners or door-choice runners.

Where did multiplier gates actually come from?

From the 2021-2022 gate-runner wave: hyper-casual games built on running crowds whose size changed as they passed numbered doors. Mob Control (May 2021) and the titles around it turned the mechanic into a genre. Numbers in games are older than that; a number that re-prices your run every two seconds is not.

Did Last War: Survival invent the gate ad?

It industrialized it. Gate runners existed as games and as ad formats before 2023; Last War's contribution was running gate-runner ads as the acquisition front end for a 4X base builder, at a scale that made the formula the strategy category's default.

Why does Mob Control outrun Last War on tracked volume now?

Two directions at once: Voodoo runs a full-width programmatic template that produces tens of thousands of plans, while Last War has throttled buying after shifting from new-user acquisition to working its existing base, as industry reporting and the thin tracked footprint both indicate. The two facts are about different strategies, not a head-to-head creative contest.

Does "the game looks exactly like the ads" copy prove anything about honesty?

It shows positioning, not verification. The line appears on the advertiser's own image creative and is aimed at an audience trained to distrust gate ads. Whether any ad honestly represents its game is a product question this article's delivery data cannot answer.

Where does the data come from?

Delivery counts, coverage and exposure estimates come from CreativeScope for Mob Control and Last War: Survival Game over the stated windows. Historical and scale facts come from published sources quoted at magnitude. No third-party numbers are mixed into CreativeScope figures.
