Candles Reconstruction

(Published on 9. January 2026, 21:28 by KNT)

Place candles into some empty cells. A candle has a height of 4 minus the amount of neighbors also containing candles. No candle may have all four neighbors filled (as then it would have height 0).

Clues outside the grid give the sums of heights of connected candles in order, where empty cells separate groups. A question mark can be any nonzero value.

A 7x7 example is provided:
