4 best free resources for game level design (2026 Guide)

If I had to choose, I could say that the four best free resources for game level design are The Level Design Book, World of Level Design, Tommy Norberg’s LevelDesignTechniques, and Alexander Kullman’s “In Pursuit of Better Levels.” Together they cover everything a self-taught level designer needs: theory, engine practice, technique vocabulary, and research-backed judgment. None of them costs anything, and all four are built by people who ship or teach levels for a living.

This applies to you if you’re starting from zero, switching into level design from another discipline, or already working in games and trying to fill gaps in your foundations. If you want a comparison of what each resource does best, where each one falls short, and a sequence for using them, that’s what the rest of this article provides — plus how to turn that study into portfolio evidence studios can actually evaluate.

Mid-October, by the way, is the right week to be reading this. Blocktober is running, level designers everywhere are posting their rough blockouts next to finished levels, and the gap between the two is exactly what these four resources teach you to close.

What Level Design Actually Asks of You

Level design is the practice of planning and building spaces for video games. That definition comes from the community-run Level Design Book, and it’s worth pausing on, because every word is doing work. Planning. Building. Spaces. You’re not painting backdrops — you’re deciding where a player walks, what they see when they turn a corner, and how quickly they understand a place.

That’s a strange skill set to acquire. Half of it is architecture: sightlines, circulation, scale, the way a room reads before anyone explains it. The other half is invisible — pacing, difficulty curves, teaching a mechanic without a tutorial popup. No single course covers both well. Which raises the question of whether free resources can.

They can, for one specific reason: the printed level design book is a dying format. The Level Design Book’s own introduction argues that print tends to doom level design books to obsolescence within a few years, because the discipline keeps moving. The knowledge that survives lives online, updated by working designers, and much of it is free. What costs money is rarely the knowledge — it’s packaging.

There’s a second reason free works here, and it matters more. Level design is assessed on evidence, not credentials. A lead reviewing your application can’t verify what you read. They can verify whether your blockout controls a player’s attention, whether your layout survives a playtest, and whether your iteration notes show you understood why version two beat version one. Those are things you build, not things you buy.

So the honest framing for this list: four free resources, each covering a different layer of the craft, with real limitations I’ll name rather than hide.

The 4 Best Free Level Design Resources at a Glance

Read the table as a dependency chain, not a ranking. Theory tells you what matters. Tutorials get your hands on the tools. Technique pages give you names for what you’re seeing. The writeup explains why any of it works. Skip a layer and the others wobble.

Resource 1: The Level Design Book — Theory That Stays Current

Start here. If you’ve never formally studied level design, this is the foundation, and it’s free in the most serious sense: a nonprofit volunteer project, published under a Creative Commons BY-NC-SA 4.0 license, with an explicit promise on the site that it will never be paywalled and that all translations and copies must also remain free. The book’s authors page credits Robert Yang as founder — an indie developer known for the Radiator games, who also contributed levels to Black Mesa Source — alongside contributors like Andrew Yoder, whose credits include Paladins and Warframe.

What’s inside is structured like a curriculum rather than a blog. The Process section covers core workflows and the language of the discipline, which the book itself flags as essential for beginners and students. Case studies take apart real levels — the annotated path diagrams through Dark Souls’ Undead Burg are the kind of figure you’ll go back to — and the histories section traces where the craft actually came from. There’s even a notes-for-educators page, which tells you something about who relies on it.

Two honest caveats. First, the book states plainly that it’s heavily under construction; some pages are thin, and structure may change. That transparency is a feature, not a bug — you always know where you stand. Second, it’s a theory book. It will not teach you Unity or Unreal. It teaches you what to build and why, then points you toward a tools appendix listing level editors and moddable games so you can go build it.

For a beginner, that division of labor is exactly right. Trying to learn theory and a full engine at the same time splits your attention until neither sticks. Read first. Build second. The book is also worth following over time — its maintainers intend to keep updating it as the discipline evolves, which no printed level design book can promise.

Resource 1: The Level Design Book — Pros & Cons

Pros:

• Free in the strictest sense: CC BY-NC-SA 4.0 license, an explicit no-paywall promise, and translations that must also stay free
• Structured like a curriculum, not a blog — Process, Case Studies, and Histories sections, plus a notes-for-educators page you can use as a self-study syllabus
• Maintained online, so it updates with the discipline instead of going stale like printed level design books
• Case studies use annotated diagrams (the Dark Souls Undead Burg path breakdown) rather than vague screenshots

Cons:

• Heavily under construction — some pages are thin, and the maintainers say so openly
• Zero engine or tool tutorials; you’ll need another resource to build anything
• Volunteer-run, so update pace depends on contributor availability
• Depth varies by section, so it works better as a structured read than as a reference you dip into randomly

Resource 2: World of Level Design — Learn by Building

Theory without tools goes nowhere, and this is where World of Level Design earns its place. Alex Galuzin, a self-taught level designer turned 3D instructor, has been publishing tutorials on the site since 2008. Hundreds of them. The archive tracks the industry’s tool history — UDK, CryEngine, Source, then Unreal Engine 4 and 5 — along with 3D modeling, preproduction planning, and workflow fundamentals.

The site’s clearest teaching asset for new level designers is its Blocktober quick-start guide, which defines the blockout better than most paid courses manage. A blockout — also called a blockin, whitebox, graybox, or blockmesh — is the phase where you build your level from primitive shapes: cubes, planes, cylinders. No textures. No props. Your only jobs are layout, size, scale, proportions, and composition, plus flow, pacing, and playable space if the level needs to actually run. Galuzin’s framing has stuck with a generation of designers precisely because it’s this concrete.

Galuzin also wrote Preproduction Blueprint, a planning methodology for environments and levels that shows up on nearly every “what should I read” thread in level design communities — and his tutorial philosophy is worth absorbing even when the specific engine content ages: plan before you build, block out before you polish, finish what you start.

Be aware of the site’s current shape. Recent output leans toward game environment art, with a Patreon offering asset collections and modular environment courses. The free level design archive remains online and valuable, but the newest material serves environment artists more than pure level designers. For blockout discipline and workflow habits, though, the fundamentals don’t expire. A 2015 tutorial about planning a layout teaches planning; the screenshots just have an older engine version.

Resource 2: World of Level Design — Pros & Cons

Pros:

• Practice-first: hundreds of tutorials that get your hands on an actual editor, not just theory
• The clearest blockout definition available free — its Blocktober quick-start guide alone justifies a bookmark
• Spans the industry’s tool history (UDK, CryEngine, Source, Unreal), so the workflow thinking transfers to whatever engine you use next
• Galuzin’s preproduction planning methodology is the site’s underrated gem and shows up in nearly every community reading list

Cons:

• Recent output leans toward environment art and Patreon asset collections, not pure level design
• Older tutorials reference dated engine versions — the principles hold, the screenshots don’t
• It’s an archive, not a sequence; there’s no guided path from your first blockout to your tenth
• Mixed depth across 17 years of content, so expect some archaeology to find the good material

Resource 3: Tommy Norberg’s Level Design Breakdowns

Some people learn from chapters. Others learn from diagrams with arrows on them. If you’re the second kind, Tommy Norberg’s site is your resource.

Norberg is a level designer by trade, with a career that has run through scripter, world designer, game designer, level designer, and lead level designer roles — he was lead level designer on the co-op portion of Starbreeze’s Syndicate — and he now teaches level design at The Game Assembly in Sweden. He’s probably best known for his social media breakdowns: annotated game images and threads explaining spatial design decisions, like why breaking sightlines stays central to world building, that circulate constantly in level design circles.

His site’s centerpiece is LevelDesignTechniques, which he describes as “a wikipedia of sorts.” The organizing idea is borrowed from Vitruvius, the Roman architect who argued every building needs firmitas, utilitas, and venustas — strength, utility, beauty. Norberg translates these into the three core values of level design: spaceplanning, gameplay, and composition. Under those he nests an actual reference library: flow and rhythm and core loops under gameplay; leading lines, focal points, rule of thirds, symmetry, silhouettes under composition; believability, optimization, sightline-blocking under spaceplanning. There’s a section on how players mentally map game worlds — landmarks, nodes, hubs, edges, the golden path — that leans on urban planning’s classic ideas about how people read cities.

One entry deserves special mention, because it cuts against common advice. Norberg argues “function before form” should be abolished as an idiom: all three values have to walk hand in hand for a level to work. It’s a strong position, and it’s the kind of opinion you can actually test against your own blockouts.

Fair balance, since this article is about credible sources: even The Level Design Book’s own recommended-reading page acknowledges Norberg’s influence while cautioning that the image-heavy format can oversimplify player psychology and flatten nuance. That criticism is worth holding onto. Diagrams compress truth to make it teachable. Use his pages as a vocabulary and a checklist, then verify against your own playtests. He’s also been at work on a book, Building Game Worlds, based on those popular breakdown threads — worth watching for, not yet a substitute.

Resource 3: Tommy Norberg’s LevelDesignTechniques — Pros & Cons

Pros:

• Fastest lookup format in level design education: every technique named, defined, and shown visually
• The Vitruvian framework (spaceplanning, gameplay, composition) makes the whole discipline memorable instead of a pile of disconnected tips
• Written by a shipping lead level designer (Starbreeze) who now teaches the craft at The Game Assembly — it’s a working professional’s mental model
• Grows continuously as a free reference, and his social threads extend it with current breakdowns

Cons:

• The image-led format can oversimplify player psychology — a limitation even The Level Design Book’s reading list flags
• It’s an encyclopedia, not a course; there’s no prescribed order, so beginners can wander
• Some material lives in social threads rather than the site itself, so it’s not fully consolidated
• His forthcoming Building Game Worlds book is still in development, so the site remains a collection rather than a finished system

Resource 4: Alexander Kullman’s “In Pursuit of Better Levels”

The first three resources teach you what level design is and how practitioners think. Alexander Kullman’s writeup does something rarer: it shows the reasoning underneath, with receipts.

Kullman is a senior game and level designer with six years shipping multiplayer and open-world content — owning locations from macro blockouts down to cover placement and narrative set dressing. For this document, he spent three months researching level design knowledge, cognitive science, and architecture, then combined what he found with his own solutions. The result is a 127-page guide called “In Pursuit of Better Levels,” free on his site, with sources cited inside the document itself.

That last detail separates it from almost everything else in this space. Most level design advice — including plenty on this very page — is craft wisdom: accumulated experience, valuable but hard to audit. When Kullman tells you something about how players read space or remember layouts, the citation is right there. You can disagree with his conclusions after checking the underlying research. For designers who want to move from following rules to understanding them, this is the bridge.

The format suits that goal. It’s a dense working document, not a course with videos and exercises. Read it after you’ve blocked out a few levels, not before — the sections on cognition and architecture hit differently once you’ve felt a player ignore your carefully placed landmark for the third time.

Kullman also publishes shorter, bite-sized level design tips on LinkedIn, which work as a low-commitment preview of his thinking before you commit to the full document.

Resource 4: Alexander Kullman’s “In Pursuit of Better Levels” — Pros & Cons

Pros:

• Sources are cited inside the document — you can audit or challenge every claim instead of taking it on faith
• Bridges the gap most guides skip: how research in cognitive science and architecture actually connects to shipping decisions
• 127 pages of condensed judgment from a senior designer with six years on multiplayer and open-world content
• Free bite-sized tips on LinkedIn work as a low-commitment preview of the full writeup

Cons:

• Dense working document with no exercises, videos, or structured practice — you bring the hands-on part yourself
• Best read after you’ve built some blockouts; early-stage beginners may find the research sections abstract
• Single-author perspective, even though it’s researched and sourced
• Reads as a reference for judgment rather than a start-to-finish method

How to Combine These Free Level Design Resources

Used in sequence, the four resources reinforce each other. Used in parallel, they tend to dissolve into browser tabs. Here’s a pattern that works.

Weeks 1–2: vocabulary. Read The Level Design Book’s introduction and Process section. Don’t touch an engine yet. Write down every term you can’t define — golden path, pacing, flow, readability — because you’re about to need them.

Weeks 3–6: hands. Pick an engine — Unreal is free and best covered by World of Level Design’s material — and block out small spaces: one room, then a corridor loop, then a two-floor space with a choice. The scale of the challenge matters less than finishing. Norberg’s technique pages become your reference during this phase: something in your layout feels wrong, you look up sightlines or landmarks, you find the term, you find the fix.

Weeks 7–12: judgment. Now read Kullman’s writeup end to end. With a dozen blockouts behind you, his research-backed sections stop being abstract and start explaining things you watched players do. This is also when you revisit The Level Design Book’s case studies, because you’ll finally read them the way working designers do: looking for decisions, not descriptions.

Throughout: keep notes. A one-page document listing each blockout, what you tested, and what changed is the beginning of a portfolio. It’s also the beginning of judgment — patterns in your own mistakes teach faster than any external resource.

⚔️ Myth vs. Reality

Myth: You should finish all four resources before building anything.

Reality: Reading without building produces vocabulary, not skill. The resources interleave: read one LDB chapter, sketch the layout it describes, block it out in an engine, then check Norberg’s technique pages to name what went wrong. A single loop like that teaches more than a month of passive reading.
