Reviews describe the satisfaction of seeing an idea actually work in a circuit. It suits players who enjoy the time spent thinking through technical problems.
What makes it fun
Make the circuit work
Decide which chip handles each task while fitting the code and connections within the limits. Seeing the circuit produce the intended signals makes those decisions pay off.
Keep refining a working build
Once a circuit works, you can rebuild it to reduce cost, power use, or lines of code. The same puzzle leaves room for a different design.
The manual is part of the puzzle
Compare the assignment email with the manual’s datasheets and diagrams. Finding the component specifications you need becomes part of solving the puzzle.

A typical run
A reviewer enjoyed the constraints of code length and chip connections while aiming first to finish levels with clean code. Optimisation was not their only goal.
What sets it apart
Reading documentation is part of the choice. Reviews praise consulting technical references, while another describes more study than expected.
Learning curve and difficulty
A reviewer partway through felt pushed towards mathematical shortcuts to shorten code. Their point was that writing an idea out at length was not always sufficient.
What players like
Consulting datasheets and manuals is part of the appeal for reviewers.
Reviews highlight the enjoyment of improving circuits and code.
Reviewers value the satisfaction of making a solution work.
Common complaints

Reviews describe fitting and wiring components on a small board as more burdensome than enjoyable.
Who it’s for
For players who enjoy reading references and building solutions under constraints.
Who might not enjoy it
