Matt says: “This is Ransū, which mean “random numbers” in Japanese. The idea is to have a grid of numbers and hide the time inside it.
There is a hidden mode and a normal mode. The hidden mode consists of using 6 segments instead of 7 by having only the junction (T, L and I shaped) and extremity of the digit visible.
The normal mode has “full rectangle” digits, or could be a conventional 7 segments.
The useless numbers change to a random number when the time, on that column or row, change. Or can be previous/next digits. The 1st model consists of a 6×3 grid with the exact time on the 2nd row.
The 2nd model consists of a 4×4 grid with the exact time positioned as a column. This one also include the month and date, which fully take the 1st or 4th row.
Peoples who like Sudoku, or any other logic-based, combinatorial number-placement puzzle, are the target market. Here are some examples of the time in different modes:”
