A mobile game takes anywhere from about two months to more than a year. The main factors are genre, art style, platforms and team size. A simple hyper-casual game can ship in one to three months, a casual puzzle game in three to six, and a mid-core or 3D game often needs six months to a year or more.

Studio estimates vary, and that tells you something: scope drives the schedule more than any rule of thumb. This guide shows what each stage involves and how to plan a realistic launch date.

What is the typical timeline by game type?

Based on estimates from Ocean View Games:

• Hyper-casual: 1 to 3 months
• Casual and puzzle: 3 to 6 months
• Mid-core (action, platformer): 6 to 12 months
• Complex RPG, multiplayer or 3D: 12 months or more

Other studios publish different ranges. Stepico, for example, puts mid-core mobile games closer to 12 to 18 months. Treat these figures as starting points, not promises.

Development stages and how long they take

Every project moves through pre-production, prototyping, full production, QA, and store submission. Ocean View Games breaks a hyper-casual project into one to two weeks of pre-production, three to six weeks of core development, one to two weeks of polish and QA, and one to two weeks for store submission.

Larger games spend far more time in production and QA, but the order stays the same. Ocean View also notes that a minimum viable product usually takes 30 to 40 percent of the full production timeline. Building one first shows whether the concept deserves the rest of the budget.

Why 3D games take longer

A 3D game adds work that 2D projects skip: modeling, texturing, rigging, animation, lighting and optimization for mid-range phones. Each asset has to look good and stay light enough to run smoothly on older hardware.

Multiplayer adds more. Ocean View Games observes that the networking layer alone can take as long as an entire single-player game. A studio offering a 3D game development service should be able to tell you early which assets and systems carry the most schedule risk.

For reference, Juego Studio’s timeline guide cites Temple Run at about four months and Pokémon Go at about two years. The difference came from scope, not talent.

What changes the schedule

Several factors move the date more than anything else:

• Number of platforms, since each adds testing and store requirements
• Art style, with 3D and hand-drawn animation taking longer than simple 2D
• Backend needs such as accounts, cloud saves and live events
• Monetization systems that need balancing and playtesting
• Team size and how quickly the studio gets approvals from you

Common Mistakes to Avoid

• Setting a launch date before defining scope
• Skipping the prototype and going straight to full production
• Adding features after production has started
• Leaving QA and store submission to the last week
• Forgetting that review and rework take time

Best Practices

1. Write a one-page brief covering genre, platforms, art style and monetization.
2. Build a playable prototype before committing to the full schedule.
3. Rank features and decide which can wait for version 1.1.
4. Ask your studio to list assumptions behind its estimate.
5. Add buffer time for QA, store review and device testing.
6. Plan post-launch updates as a separate phase with its own budget.

Working with Cobweb Games

Cobweb Games is a custom game development studio that offers mobile, Unity, Unreal Engine and 3D game development, along with prototyping, QA and live operations. If you are comparing a game development service for your project, a short call is usually enough to get a scoped timeline.

FAQ

How long does it take to make a simple mobile game?

A simple hyper-casual or casual puzzle game usually takes one to six months, depending on the amount of content and polish.

Does a 3D game take twice as long as a 2D game?

There is no fixed ratio. A 3D game adds modeling, rigging and optimization work, so it usually takes longer, but a small 3D project can finish before a large 2D one.

Can a game be built faster by adding more developers?

Only to a point. Extra people help when tasks can run in parallel, such as art and programming, but design decisions and approvals still take time.

How long does store approval take?

Review times vary by store and by game. Allow at least a week in the schedule and more if the game has in-app purchases or age-rating questions.

Conclusion

Mobile game timelines run from weeks to well over a year, and the difference comes from scope, art style and platforms. A defined brief and an early prototype give you a schedule you can trust.
