MHRD
A text-only puzzle game that starts you with a single NAND gate and has you write hardware in a small description language: ANDs, adders, and finally the design of a working CPU. You play a new hire at a fictional company called Microhard, filling twenty-odd specifications in order. Made by Funghisoft.
puzzleprogrammingsimulationBombe
A logic puzzle where you do not clear the Minesweeper board yourself: you write rules that act on the numbered regions, and a checker verifies them. Rules that pass are applied automatically to every board from then on, leaving only the situations no rule has reached. A solo project by Charlie Brej.
puzzlelogicautomationAutonauts
An automation puzzle in which you land on an empty planet, chop and quarry by hand, and then teach robots the steps you just performed so they can do them for you. With short Scratch-style scripts and one small memory allowance per bot, you grow a production line from farming to industry. Made by Denki, in Scotland.
puzzleprogrammingautomationThe Signal State
A 2D logic puzzler where you slot modules — AND, NOT, attenuators, sample-and-hold — into a rack and patch them with cables carrying voltages from -100 to 100 until the output waveform matches the spec. Reckoner Industries builds it on modular synthesis, framed as repairing the irrigation of a ruined farm.
puzzleprogramminglogicKaizen: A Factory Story
A 2D automation puzzle set in 1986 Japan: lay arms and tracks across a green workbench, program a timeline of commands, and build assembly lines for calculators, camcorders and arcade cabinets. Made by the original Zachtronics team under their new studio Coincidence, with a pachinko-flavoured solitaire on the side.
puzzleautomationprogrammingSilicon Zeroes
An open-ended puzzle set in a 1960s Silicon Valley startup, where you wire simple parts — adders, multiplexers, latches — into a working CPU with instruction decoding and pipelining. From PleasingFungus Games, maker of Manufactoria, a CPU-design game that hides the bits and shows only how the parts behave.
puzzleprogramminglogicwhile True: learn()
A visual-programming puzzle themed on machine learning: you drop nodes on a canvas, wire them together, and sort nine kinds of data (three shapes in three colors) into the right outputs. A handful of parts named after real algorithms—decision trees, perceptrons—build up a cat-to-human translation system. By Luden.io.
puzzleprogrammingsimulationEXAPUNKS
A hacking puzzler set in a 1997 cyberpunk world: you write pseudo-assembly for tiny programs called EXAs and send them through the networks of banks and universities. With a printable underground zine as its manual, it pulls bottomless depth from a few verbs — a Zachtronics game.
puzzleprogramminglogic7 Billion Humans
A parallel-programming puzzle where one shared instruction list runs across a crowd of workers who carry and sort data cubes to clear each level. The sequel to Human Resource Machine, built by Tomorrow Corporation from a small set of commands.
puzzleprogramminglogicTIS-100
An assembly-language programming puzzle: you write code across a grid of tiny parallel nodes to repair a broken computer. Each node holds two registers and barely a dozen instructions, and passing data between nodes can deadlock — inside those constraints you compete on cycles, instructions and node count. From Zachtronics, makers of SpaceChem and Opus Magnum.
puzzleprogramminglogicTuring Complete
A programming puzzle that has you wire everything up from a single NAND gate — logic gates, an adder, registers, and finally a CPU running an assembly language you designed yourself. A solo-developed game about proving that computers aren't magic.
puzzleprogramminglogicHuman Resource Machine
A puzzle game where you feed a dozen commands to a tiny office worker between an inbox and an outbox, building 'programs' from sorts to multiplication to prime factorization. From World of Goo's Tomorrow Corporation, it hands you assembly-style thinking via drag-and-drop.
puzzleprogramminglogicInfinifactory
A first-person 3D puzzle where you build factories from blocks and conveyors to assemble whatever your alien captors order. SpaceChem made three-dimensional: a tiny verb set opening onto bottomless optimisation, from Zachtronics.
puzzleautomationprogrammingSHENZHEN I/O
A programming puzzle in which you play an engineer at a fictional Shenzhen firm, writing terse assembly for cramped virtual microcontrollers and wiring circuits onto a board to build client products. Zachtronics ships no tutorial — its 30-plus-page datasheet manual is the first puzzle.
puzzleprogrammingoptimizationOpus Magnum
A 2D puzzle where, in an alchemist's workshop, you combine rotating and extending arms with tracks to ferry and bond atoms into potions and metals. The board and part count are unlimited, so the contest is less about clearing than about how elegantly, quickly, and compactly you build — Zachtronics' signature work.
puzzleprogrammingautomationSpaceChem
A 2D puzzle where you program two 'waldos' to grab, carry, and bond atoms, building factories that turn raw molecules into products. You don't find a solution — you build one. The design-based puzzle that launched Zachtronics.
