Logic Masters Deutschland e.V.

Rules: Rules: Normal Sudoku Rules Apply. Place digits 1-9 in every row, column and box.

Blue Cell is a battery and yellow cell is a bulb. Green and Purple lines are insulated wires. Complete the circuit by constructing 3 non-insulated aka naked wires in the grid joining i) battery and green wire end, ii) Battery and purple wire end iii) Purple wire end and the bulb

Whichever cell the naked wires passes through is electhreecuted to become a multiple of 3 (Including the junctions of battery, bulb and insulated wires). Wire can travel diagonally. There are no dangling wires and loose ends. Additionally, all the multiples of 3 in the grid must be part of the circuit (Battery, bulb or wires)

German Whispers: Consecutive digits on the green line must differ by 5 Renban: Numbers on the purple lines are consecutive but could appear in any order Sandwich: Numbers outside the grid give sum between 1 and 9 in the row or column Black Kropki dots: Cells separated by black dots are in 1:3 ratio White Kropki dots: Cells separated by white dots have a difference of 3
