While constructing one of these 6x6-Sudokus with Global Entropy, I discovered some interesting geometric properties that lead me to make some more of them. The most interesting four of them have been compiled here. Enjoy!

Rules:

This puzzle consists of four seperate Mean Minis with increasing difficulty.

Fill each grid with six of the digits 1-9, such that no digit repeats in any row, column or box. Which digits are used needs to be determined individually for each grid.

Global Entropy rules apply: Any 2x2-area must have at least one low (1,2,3), one medium (4,5,6) and one high digit (7,8,9) in it.

Additionally, the following variants are used:

Grid 1 (Killer): Digits in a cage must sum to the indicated total.

Grid 2 (Kropki): Digits seperated by a white dot must be consecutive. Digits seperated by a black dot must be in a ratio of 1:2. Not all dots are necessarily given.

Grid 3 (Renban / Little Killer): Digits on a purple line must form a set of non-repeating consecutive digits. Digits along the indicated diagonal may repeat and must sum to 21.

Grid 4 (Sandwich): The clues outside the grid indicate the sum of the digits between the highest and the lowest digit in the respective row/column.
