PUZZLE TECHNIQUES

SOLVING TECHNIQUES LIGHT UP PUZZLES

Only solve Akari puzzles using logic. Here are some solving methods:

LOOK FOR CELLS WITH NUMBER 0

The squares around number 0 cannot have lights. So we can place crosses.

PLACE LIGHTS WHERE FREE SIDES MATCH THE NUMBER

The cell with number 3 has only three sides free and the cell with number 2 (due to the influence of other lights) has only two side free. So we can place the lights.

PLACE A LIGHT IN ROWS OR COLUMNS WITH 1 CELL LEFT

Look at column C1-C4. You may only place a light in cell C4.

DIAGONALS AROUND NUMBERS 3 AND 4

If you place a light at a diagonal of number 3 or 4, than you cannot place enough lights around those numbers. So all diagonals of numbers 3 and 4 must be excluded and may not have a light. They all get a cross.

Whe a cell with number 2 is blocked at one side, than you can also place crosses in the diagonal cells.

NUMBERS 3 AND 1 AS DIAGONALS

When we have numbers 1 and 3 as diagonals then we can place 2 lights and two crosses at the side where they don't touch.
