How to Make a Game with AI, From the Idea to Your Phone

Before you start: pick a game you can finish

The biggest choice happens before you type anything. A first game should be small enough to finish and clear enough to describe in one breath. "An open-world RPG with crafting, a story and a hundred quests" is a wish list. "A fox leaps between floating ledges collecting berries while beetles patrol below" is a game.

Good first picks are genres with one core action and a clear loop: an endless runner, a match-3, a tower defense, or a survivors-like arena where your hero attacks on their own and you only steer. Each has a verb you can name, a pressure that pushes back, and a way to win or score. If you are stuck for an idea, game ideas for beginners sorts a list by how hard each one is to tune.

Pick one. You can make the second one next week.

Step 1: Describe the game in one sentence

Open the workbench at app.tyrbo.ai in your browser. There is nothing to download. The first box asks for your game, and one sentence is enough if it covers three things: what you do, what you avoid, and what you are trying to reach.

• Weak: "A space game."
• Better: "A tiny ship at the bottom of the screen shoots upward at waves of alien ships that swoop at you."
• Best: "A tiny ship shoots upward at swooping alien waves, and every boss you beat lets you pick one of three weapon upgrades."

The third sentence hands the AI a loop (shoot, survive, upgrade) and a reason to keep playing. You do not need genre words, but they help: "tower defense", "match-3" or "platformer" tell the planner which family of systems to start from. For the full craft, read how to write a game prompt.

Step 2: Answer a few questions

Next, Tyrbo asks a short set of questions about what your sentence left open: portrait or landscape, how a run ends, how hard it should start, what the art should look like. Each question arrives with a best guess already selected. If the guess fits, tap Continue. If it does not, pick another option or type your own answer.

This step fixes much of the game's shape, so give it real attention. Two answers matter more than the rest:

• Orientation. Each game has one, portrait or landscape. Portrait suits one-handed play on a phone; landscape suits racing and wide side-view levels.
• The look. Name a style, not an adjective. "16-bit pixel art in a bright palette" or "chunky toy-like 3D" steers far better than "cool". There are 24 look directions, from tiny 8-bit pixels to voxel blocks, ink sketch and paper craft.

Step 3: Read the plan before anything is built

Before any code exists, you get a plan: a title, a short pitch, a list of every part of the game, and concept art. Signing in to see the plan and the concept art is free.

Read it like a producer, not a fan. Ask yourself:

1. Is the core loop what I meant? If the plan says enemies come in endless waves and you wanted ten hand-made levels, say so now.
2. Is anything missing that I care about? A shop, a boss, a daily challenge.
3. Is anything here that I do not want? Cutting a part now is cheaper than cutting it later.
4. Does the concept art look like the game in my head?

Changing a plan is just a reply. Changing a built game is possible too, but every change after the build is more work than a change on paper.

Step 4: Let it build, then play it on your phone

When you approve the plan, Tyrbo builds the game. It starts from a library of tested parts: a grid board, movement, side-view bodies, a heads-up display, level progress, card layouts, and map recipes for arenas, dungeons, caves, race tracks and tower-defense lanes. Whatever your game needs that the library lacks, the AI writes as new code that belongs to your game. Physics comes in only when the game has bodies that fall, bounce or collide. Building runs on paid plans with monthly credits.

When the build is ready, scan the code with your phone's camera and the game opens there. Play it on the phone, not just in the browser preview. The phone is where you learn whether buttons sit under your thumb, whether text is readable at arm's length, and whether a run feels too long while you wait for coffee.

Play three runs before you change anything. One run misleads; a pattern across three does not.

Step 5: Tune it by talking to it

Now the real work begins. Tuning is where a working game becomes a good one, and you do it by describing what you felt and what you want instead.

Useful change requests are specific and tied to a moment:

• "The first wave is too easy; I won without placing a second tower. Make wave one need two towers."
• "Jumping feels floaty. Make the fall faster than the rise."
• "The coins are hard to see against the grass. Give them a dark outline."

Vague requests like "make it more fun" give the AI nothing to measure. Say what happened, when, and what you expected.

Ask for testing helpers too. The AI can write tools inside your game for you: a cheat to skip to level 10, a button that spawns a boss, sliders for enemy speed and spawn rate. Sliders are the quickest way to tune, because you can feel five versions of a number and then tell the AI which one to keep.

Step 6: Get it ready for other people

A game you enjoy alone is a prototype. A game strangers can play needs things nobody notices until they break. Tyrbo checks these before a game leaves the pipeline: no soft-locks (states where the player is stuck with no way forward), smooth play on low-end Android phones, ads and purchases wired in, leaderboards live, and a signed build that you own, with full commercial rights.

Android is the first store. You get the signed build and a step-by-step checklist for Google Play, and how to publish a game on Google Play walks through the store side in detail.

Mistakes that waste a first game

• Describing features instead of play. "It has a shop, skins and achievements" says nothing about the minute-to-minute game. Start with the verb.
• Skipping the plan review. Most disappointment traces back to a plan nobody read.
• Tuning on a laptop. Mouse play hides every thumb problem.
• Changing five things at once. Make one change, play it, then make the next. Otherwise you cannot tell which change helped.
• Growing the scope before the core is fun. Add a second world after the first one makes you want to keep playing.

What AI does not do for you yet

Honesty matters here. AI can plan, build and draw a game, but it cannot tell you whether the game is fun; only playing can. It will follow a weak idea as faithfully as a strong one. Its first pass at difficulty is a guess. And long, story-heavy games with branching dialogue are still much harder to get right than tight arcade loops. Treat the AI as a tireless builder and keep the taste for yourself.
