Logic Masters Deutschland e.V.

Standard Sudoku Rules Apply:
Fill in the grid with the integers 1-9 so that the numbers are not repeated in each row, column, and each 3x3 area (grid) separated by a bold line.

Renban Rules Apply:
Digits on a purple line form a set of non-repeating consecutive digits in any order.

Kropki Rules Apply:
Digits separated by a black dot are in a 1:2 ratio. NOT all the black dot are given.

The Max Profit Arrows Rules Apply:
Regard the digits on the arrow as a given stock in order. You want to maximize your profit by choosing a single day to buy one stock and choosing a different day in the future to sell that stock. The digit in the circle equals the max profit of the attached arrow. If a single circle attaches more than one arrow, they will share the same max profit in the circle. In other words, starting with the circle, the digit on the arrow would be an array prices[i] in order. The digit in the circle=MAX{prices[k]-prices[i]}(k>i) Here is an example:(5)->9->2->6->4->7->5->1 Max profit:You buy for 2 and sell for 7. You can NOT buy for 1 and sell for 9 to get 8, since 1 came later than 9.
