    The method

    How it's made

    One method, every genre.

    The same eight steps made every ad here. What changes is the look, the rules and the story each game sells in 30 or 45 seconds.

    1. Brief

      A one-page brief per game: rules, HUD, and a beat sheet with a hook, the core loop, a payoff and an end card.

    2. Style anchor

      One sheet holds the look: pieces, UI parts and the hero character together. Every later image passes it as a reference.

    3. Asset sheets

      Characters, pieces, HUD, banners, logo and icon come out as sheets on transparent backgrounds, then a script cuts them into sprites.

    4. Gameplay in code

      A video model cannot keep a board, a battle or a pile of blocks honest, so the gameplay is a deterministic engine: match rules, a battle log, rigid body physics or a dice board. Every number on screen comes from it.

    5. Blender layout

      Blender stages each shot from the engine's coordinates: an arena, a board, a clay diorama, or puppets and props from image to 3D. Its render fixes the camera and composition of the painted frames.

    6. First and last frames

      Each cinematic shot gets a finished first frame and last frame. Seedance 2.5 animates the move between them.

    7. Sound

      ElevenLabs Music composes a theme to the shot timeline. ElevenLabs Sound Effects makes the game sounds, placed on the engine's events, mixed for phone speakers.

    8. Review loop

      Scenario asset analysis reviews key frames against the brief as a mobile UA creative director; flagged frames are reworked.

    Agent skill

    Teach your agent to make a mobile ad

    An Agent Skill for Claude Code, Codex and any agent connected to Scenario MCP. Its SKILL.md holds this method for match-3, puzzles, battlers, physics, dice boards and crowd runners, and has the agent pick the best current model for each asset. Its scripts cut sheets into sprites, run match-3, battle and crowd logic, register a painted arena onto the engine's coordinates, roll seeded dice in Blender, keep floating numbers apart, place sound cues, check the finished ad and render an explanatory how-to styled in the game's own look. Unzip it into your agent's skills folder and describe your game.

    Agent skill

    Teach your agent to make a mobile ad

    scenario-mobile-ua-ad holds the method behind these eight ads: the brief, the style anchor, the gameplay engine, the key frames, the sound and the review loop. It works with Claude Code, Codex and any agent connected to Scenario MCP.

    1. Download the ZIP.
    2. Unzip it into your agent's skills folder, so that the folder scenario-mobile-ua-ad/ (with SKILL.md inside) sits there. For Claude Code that is ~/.claude/skills/. Then reload the agent.
    3. Ask it for a mobile game ad, with the genre, the core mechanic and the style.

    Your agent needs Scenario MCP with credits. The scripts run on your machine with Python 3, ffmpeg and Playwright; Blender only for the optional layout steps.
