In this game, you can…

• …cram a working gadget into absurdly tight code limits, like 9 or 14 instructions, until every single word matters.
• …build your own devices in the sandbox, including full games people recreate inside it, like in-game Tetris.
• …wire up microcontrollers, memory, logic chips, and LCDs, then write tiny assembly programs where each instruction can run conditionally.

In this game, you can…

• …place your inputs and outputs anywhere, then build across an effectively unlimited grid with the full toolset from the start.
• …export your working solution as an animated GIF that loops forever and share the machine in motion.
• …turn raw materials into stranger products by bonding, unbonding, and transforming them in long repeating chains of steps.

In this game, you can…

• …connect multiple reactors so one puzzle becomes an entire production chain with pipes feeding outputs into the next step.
• …pack a full solution into a tiny reactor by shaving parts, rerouting, and ending on a precise manual switch sequence.
• …use flip-flops and timing rules to build counters and branching behavior that makes your reactor act like a program.

In this game, you can…

• …get rewarded for triggering "wrong" computer behaviors like out-of-bounds memory access or numeric overflow and still clearing the level.
• …create multiplication from scratch using only addition and subtraction, then reuse that homemade multiply in later puzzles.
• …calculate memory addresses and use them to fetch and store data, instead of only manipulating the values directly.

In this game, you can…

• …cut out a mecha model kit, snap it together, paint masked sections, place decals, then export it as a shimmering GIF.
• …wire rack-sized controllers with headphone cables to automate a future fast-food assembly line for time-traveling tourists.
• …grow a creepy cell pattern by choosing rules and iterating until the flesh-like system clicks into a target shape.

In this game, you can…

• …build a working CPU starting from a single NAND gate.
• …design your own instruction set, choose the opcodes, and write programs in your own assembly language.
• …install a keyboard, monitor, sound, network, and a file reader that can pull bytes from your real computer into the simulated machine.
