How to make a mobile game: timeline, phases, and costs by complexity

How long does it take to make a mobile game?

It depends on complexity. As directional planning bands, a hyper-casual game ships in roughly 3 weeks to 2 months, a polished casual title in 3 to 6 months, a mid-core live-service game in 12 to 18 months, and an AAA-grade mobile title in 18 to 24 months or more. In every tier the longest stretch is production, where the design becomes a finished, playable product. Understanding this range is the first step in planning how to make a mobile game that actually ships.

These are planning ranges drawn from industry consensus, not a single analyst dataset. The same idea can sit in two bands depending on art scope, multiplayer, and how much live-service ambition you build in. The four tiers below are the useful mental model for scoping a schedule.

• Hyper-casual: one mechanic, such as a tap, timing or runner loop, monetized mostly by ads. A team of 1 to 3 people prototypes many concepts and kills most of them fast.
• Casual: match-3, merge, puzzle or idle games with progression and a meta layer, usually a 4 to 8 person team.
• Mid-core: RPGs, strategy, shooters and other titles with real-time multiplayer, a deep economy and live-ops, built by 8 to 25 or more people.
• AAA-grade mobile: console-quality 3D, large worlds and cinematic production, which needs 25 to 100 or more people and a multi-year mindset.

The six phases every mobile game moves through

Every mobile game, from a weekend hyper-casual prototype to a multi-year AAA title, moves through the same six phases: concept and discovery, pre-production, production, testing and soft launch, launch, and live-ops. The sequence is stable and uncontroversial; what changes by tier is how long each phase runs. Production is the longest in every case.

1. Concept and discovery

The core idea, target audience, competitor and market fit, a rough monetization thesis, and the success metrics you will judge the game against. A few days for hyper-casual, up to 6 to 12 weeks for an AAA-grade title where the bet is large.

2. Pre-production

The game design document, a prototype of the core loop, art direction, the engine and tech decision, and a vertical-slice plan. This is also where monetization should be designed in, because it shapes progression, difficulty and the economy. Bolting it on later forces rework and stretches the schedule.

3. Production

Building the full game: gameplay systems, levels and content, art and animation, audio, backend, and the monetization economy. This is the longest and most resource-intensive phase in every tier, and the single biggest reason timelines slip.⁴ It runs from a couple of weeks for hyper-casual to 9 to 15 months for AAA-grade.

4. Testing and soft launch

QA across a device and OS matrix, balancing, and a soft launch in test geographies to read retention (D1, D7, D30), revenue per daily active user, and funnels before going global. For casual, mid-core and live-service games, soft launch is a real calendar-consuming phase, not a formality. Many overruns come from iterating here until the key metrics clear.

5. Launch and global release

App store optimization, the marketing ramp, server scaling, and launch-day operations. Short relative to production, from a few days for hyper-casual to a few weeks for the largest titles.

6. Live-ops

Events, content drops, balance and economy tuning, A/B tests, and retention and monetization work. For mid-core and AAA-grade live-service games, launch is the start of the work rather than the finish, and the cadence never ends. Sustaining that post-launch content is where most studios run short on capacity, which is the case for a mobile app development partner who can keep a dedicated team on the game after release.

What actually drives the timeline

Seven levers decide how long a mobile game takes, roughly in order of impact: the complexity of the core loop, art and animation scope, multiplayer and networking, monetization complexity, the number of platforms, live-ops ambition, and the team and process behind it. Each is something you control at scoping time, which is why an honest schedule starts with these rather than a calendar.

• Genre and core loop: a single mechanic versus layered systems with progression, a meta-game and an economy. This is the biggest single determinant because it sets production length.
• Art and animation scope: flat 2D versus stylized versus full 3D with rigging, animation and visual effects. 3D modeling, texturing and advanced animation are repeatedly named as top time and cost drivers.
• Multiplayer and networking: real-time multiplayer, matchmaking, leaderboards, voice and anti-cheat all need a scalable cloud backend. Real-time multiplayer titles commonly land in the 12 to 18 month band.
• Monetization complexity: ad-only is fast; an in-app-purchase economy with a battle pass and live events is not. Design it in pre-production rather than after.
• Platform targets: cross-platform from one engine is the norm, but adding web, PC or console multiplies the QA matrix and store compliance work.
• Live-ops ambition: a seasons-and-events roadmap requires dedicated ongoing capacity and is the main reason development effectively never stops.
• Team size, seniority and process: a small indie team takes longer than a staffed studio. Engine familiarity, reusable tech and a clear, frozen scope compress the schedule; scope creep expands it.

The practical takeaway is that the timeline is set during scoping, well before the first sprint. Getting the team shape and the scope right at the start is the cheapest way to protect a schedule, which is exactly where an experienced engineering partner earns its place.

How engine choice affects build time

Engine choice is itself a timeline decision. For most mobile games, Unity is the practical default because it deploys to iOS and Android from a single codebase, is tuned for mobile hardware, and has a deep talent pool and asset ecosystem, all of which cut build time. It powers roughly 70% of top mobile games. Unreal Engine raises the visual ceiling for console-grade 3D but adds optimization time, so it is the call when visuals matter more than iteration speed.

The wrong engine for the ambition is a classic source of rework and delay, so the decision belongs in pre-production rather than mid-production.

• Unity: mobile-first, strong for 2D and 3D from casual to mid-core, cross-platform from one codebase. The fastest path for the large majority of mobile games, and roughly 70% of top mobile titles run on it (a widely reported, directional figure).⁵
• Unreal Engine: a higher graphical ceiling for photoreal 3D and shared PC or console builds, with Blueprint visual scripting for fast prototyping. Heavier builds and longer mobile optimization are the tradeoff.
• Native (Swift and Kotlin) or HTML5: native suits very light games or deep OS integration but means two codebases and usually more total time for anything non-trivial. HTML5 and WebGL are fastest to distribute for instant-play and playable ads, but the performance ceiling limits ambitious 3D.

For most commercial mobile games the default is a single cross-platform engine, with native or web reserved for situational cases. The engine and architecture decision is the kind of pre-production call where our custom software development team helps avoid a costly redirect later.

Cost and the market behind the schedule

Cost tracks the timeline directly, because cost is roughly team size multiplied by duration multiplied by a blended rate. As representative planning bands, a hyper-casual game runs about $10,000 to $50,000, a casual title $50,000 to $150,000, a mid-core game $150,000 to $500,000, and an AAA-grade mobile title $500,000 to several million or more. The market is large but maturing, which raises the stakes on time-to-market.

The rate math makes the link concrete. North American and Western European senior game developers run roughly $100 to $200 or more per hour, so a 5 to 8 person team for a year is $500,000 to $1.5 million in labor alone. Eastern Europe and Latin America sit around $40 to $80, and South and Southeast Asia around $20 to $50. A US-based team with global delivery can hold US quality and communication while keeping the blended rate well below an onshore-only build, which is the lever that lets a studio afford a longer, healthier production and live-ops runway. Cost-band methodology draws on GoodFirms' 2026 app-cost survey; the game-specific tier bands are directional industry consensus.³

The reason the schedule matters so much is the state of the market. Mobile games earned about US$103 billion in 2025, roughly 55% of all games revenue, with around 3 billion players, per Newzoo.² But 2025 was a maturity inflection: Sensor Tower put in-app-purchase revenue at US$81.75 billion, up just 1.3%, while downloads fell 7.2% to 50.4 billion.¹ In a crowded, slow-growing market, the build that reaches players sooner and sustains live-ops well is the one that wins, rather than simply the best idea.

I am Head of Service Delivery at Resourcifi, where staffing and scheduling complex real-time builds is a large part of my week. The timeline bands here are the ones I use to scope game and live-service projects with clients, after enough overruns to know that production and live-ops are where honest planning earns its keep. When a schedule slips, it is almost always a scope decision made too late, and that is the part I care most about getting right up front.
