Yes—games can make coding, hacking, and systems concepts easier to practise. CodeCombat and Human Resource Machine are approachable starting points; Hacknet offers terminal-oriented security simulation; and games such as TIS-100, Screeps, and SpaceChem reward automation, debugging, and optimization. They teach useful ways of thinking, but playing them alone does not establish real-world security or DevOps competence.
Which game fits what you want to learn?
The games below span different kinds of practice: some use real programming languages, others use visual or custom instruction sets, and a few simulate security or automation problems. “Best” depends on which kind of thinking you want to exercise, not on a head-to-head ranking; no authoritative comparison ranks these ten games by learning outcomes.
| Game | Programming or interaction model | Most relevant practice |
|---|---|---|
| CodeCombat | Typed Python or JavaScript | Beginner syntax and immediate feedback |
| Human Resource Machine | Visual, custom command language | Breaking a task into instructions |
| TIS-100 | Custom assembly-like language | Low-level optimization and debugging |
| Shenzhen I/O | Circuits, logic, and assembly | Coordinating hardware and code |
| Hacknet | Terminal-based simulation using UNIX commands | Command-line orientation and simulated security tasks |
| Nite Team 4 | Ethical-hacking simulation | Security concepts and Linux orientation |
| Screeps | JavaScript in a persistent multiplayer world | Automation that runs continuously |
| Elevator Saga | JavaScript controlling a simulation | Iteration and performance under changing demand |
| Microcorruption | MSP430 assembly exploitation puzzles | Registers, memory, and exploit reasoning |
| SpaceChem | Automation and pipeline-style puzzles | Throughput, bottlenecks, and failure isolation |
Ten games, and what each one can teach
1. CodeCombat: a first step into typed code
CodeCombat turns typed programming into an adventure, with Python and JavaScript practice and feedback as you work through challenges. It is aimed at making computer science accessible to students. Its current official page reports 20,000,000+ total players, players in 190+ countries, 1 billion lines of code, and over 650 contributors; these are CodeCombat’s own current-page figures, not independent measures of learning outcomes.
For a beginner, the main value is seeing that code is something you write and revise to make a character act, rather than a subject limited to watching explanations. Brehan Maul, CodeCombat’s CEO, describes programming as “the ability to create things from pure imagination.”

2. Human Resource Machine: turn a task into instructions
Human Resource Machine asks you to automate office workers using a small, visual programming language. It starts with two commands and builds to an 11-command language. Optional challenges test program size and execution speed, encouraging you to look for a simpler or faster solution after you have one that works.
That makes it useful before or alongside a conventional language: the focus is on ordering instructions and reasoning about a process, without requiring readers to begin with familiar programming syntax. Its developer frames the idea this way: “programming is actually simple, logical, beautiful, and something that anyone can understand and have fun with.”
3. TIS-100: reason about low-level code and constraints
TIS-100 is an open-ended programming puzzle in which you rewrite corrupted code segments to repair a fictional machine. It uses an assembly-like language and asks players to optimize across cycle, instruction, and node counts, with sandboxes available for experimentation. The constraints make it a useful exercise in tracing what a program does and weighing competing measures of efficiency; success in its custom environment is not the same as experience with a real processor or production system.
Rank #2
4. Shenzhen I/O: connect logic, circuits, and code
Shenzhen I/O combines device-building with circuit design, logic, and assembly-language programming. Rather than treating code as the whole system, it asks you to consider how programmed components fit into a device. That makes it a distinctive way to practise decomposing a problem across hardware-like components and instructions.

5. Hacknet: practise terminal-oriented thinking in a simulation
Hacknet is described on its Steam listing as “an immersive, terminal-based hacking simulator for PC.” Its guided email missions, firewall challenges, and use of actual UNIX commands give players a structured introduction to interacting with a fictional system through a terminal. The listing also notes beginner support. Hacknet Extensions lets players create campaigns, system networks, nodes, themes, and missions, adding a route to explore how simulated environments are assembled.
Use it as an orientation to command-line interaction and security-themed puzzles, not as instruction to target real systems. Commands and obstacles in a game do not establish that someone can assess or secure a real network.
Rank #3
6. Nite Team 4: explore ethical-hacking and Linux themes
Ionian University teaching material lists Nite Team 4 under “Linux, Ethical Hacking,” making it relevant to readers seeking a security-focused simulation. Treat it as a way to encounter those themes and practise within the game’s boundaries—not as proof of real-world penetration-testing competence or authorization to test systems outside the game.
7. Screeps: automate agents in a persistent world
Screeps is a persistent-world multiplayer strategy game in which programmable JavaScript entities act continuously. It supports external editors, so players can work in a separate coding environment. Because your agents keep operating in a changing shared world, the game gives a concrete setting for thinking about event loops, APIs, automation, and feedback from a running system.

8. Elevator Saga: improve a controller against changing demand
Elevator Saga is a JavaScript simulation in which you write the logic that controls elevator movement. Its compact setup makes it practical to change a rule, observe the result, and iterate on how the system handles a workload. That is a useful way to think about instrumentation, throughput, and optimization, especially when a change that helps one situation may behave differently under another.

9. Microcorruption: investigate bugs close to the machine
Microcorruption is an exploitation game built around electronic locks and MSP430 assembly. Its low-level focus introduces concepts such as registers and memory through debugging and exploit reasoning. It provides a different perspective from a command-line simulator: instead of interacting with a system mainly through commands, you examine behavior at the level of instructions and machine state.
10. SpaceChem: see automation as a flow with bottlenecks
SpaceChem uses automation puzzles built around producing and moving outputs through a process. Ionian University informatics teaching material lists it under “Principles of Automation.” Its pipeline-style challenges invite players to consider throughput, bottlenecks, repeatability, and where a failure originates—ideas that also matter when designing automated processes outside a game.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you learn programming by playing games?
Games can help you practise a specific slice of programming: translating a goal into instructions, spotting why an attempt failed, changing the logic, and checking the result. To learn a conventional language, choose a game that uses that language—such as CodeCombat’s Python or JavaScript practice, or JavaScript in Screeps and Elevator Saga—then use the language outside the game as well. A custom or visual language can build reasoning habits, but it will not teach the syntax and tools of a language you have not used.

Are there games that teach hacking?
For terminal and UNIX-oriented simulation, Hacknet is the clearest fit in this list. Nite Team 4 supplies an ethical-hacking and Linux angle, while Microcorruption explores low-level exploit reasoning. These are bounded game experiences: they can help make concepts approachable, but they do not certify security skill, replace supervised practice, or grant permission to access real systems.
Which games help with DevOps?
No game here reproduces the responsibility of deploying and operating a real service. Several do reward habits that are relevant to systems work: Screeps makes continuous automation visible in a persistent world; Elevator Saga gives a small control problem to iterate against changing demand; TIS-100 and Shenzhen I/O emphasize decomposition and constraints; and SpaceChem makes flow, bottlenecks, and failure isolation tangible. Treat those as transferable ways of thinking, not evidence that you can deploy, monitor, or recover a production service.
Quick Recap
A practical progression from beginner puzzles to systems thinking
- Start with basic logic. Try Human Resource Machine if you want to focus on sequencing and decomposition without beginning with conventional syntax, or CodeCombat if you want to type Python or JavaScript.
- Move into a running system. Use Elevator Saga for a compact JavaScript controller, or Screeps if you want programmable agents operating continuously in a persistent world.
- Explore systems and security at the level that interests you. Choose Hacknet for terminal-oriented simulation, Nite Team 4 for ethical-hacking and Linux themes, Microcorruption for assembly-level exploit puzzles, or TIS-100 and Shenzhen I/O for low-level and hardware-like constraints.
- Carry the habit into real practice. Take the ideas that a game made visible—decomposition, debugging, observation, or optimization—and apply them to actual programming or operations tasks. The games provide feedback inside their own rules; real services, devices, and security work have requirements those rules cannot validate.
