The QiYi Kong Ming Lock Three Connection, also known as Big Triple Links, is part of the traditional Kong Ming Lock series and is based on the idea of three interlocking elements that only hold thanks to how they are carved on the inside. At first glance it seems the pieces can be separated in any way, but when trying, the design logic soon appears and that first impression fades.

The goal is the usual one within the series: find the way to disassemble the pieces following the order the assembly itself imposes and then return it to its initial state. There are no hidden mechanisms or cube-type turns: it is about reasoning visually and testing calmly. The feeling of solving it for the first time is usually satisfying precisely because the solution comes from observing the pieces well, not from applying a memorised sequence.

It is made of ABS plastic with a silver metallic finish that gives it a premium air for what is a fairly compact puzzle in size. The pieces fit firmly and don't move once assembled, typical of QiYi's care in this line. It is comfortable to hold, light and suitable for carrying from one place to another without fear of it opening by itself inside a backpack.

It works well as a bridge between simpler burr puzzles and more complex models in the series. It is also a nice gift for someone who has never tried a puzzle from this family, because the challenge is manageable and the first solve does not require too much previous experience. Its compact format makes it easy to wrap and store.

When solving it, many enthusiasts recommend concentrating first on identifying which piece has the most degrees of freedom, that is, which one can be moved a little without compromising the rest. That detail usually marks the beginning of the disassembly.
