Screw Puzzle DIY: Bolt Brain is all about freeing plates by removing pins in a smart order. Each unscrew reveals new constraints—pieces lock others in place, or holes create alternate paths. What begins as simple unfastening becomes a layered logic exercise where sequencing is everything. The interface is snappy and readable, encouraging experimentation until that one elegant route appears. It’s tactile, clear, and nicely challenging without ever turning fussy.
