Rules[edit]

Candles Example.png Candles Example Solution.png

Place some lighted candles into the grid. The candles have different heights which are determined by the location of other candles nearby. A candle with no other candles in horizontally or vertically adjacent cells has height 4. For each horizontally or vertically adjacent candle, its height is reduced by 1 (the heat of nearby candles melts wax); diagonally touching candles don’t affect each other. A candle of height 0 is not allowed. Candles cannot be placed in cells with numbers. The numbers indicate the total height of all candles in horizontally, vertically and diagonally neighbouring cells.
