Normal sudoku rules apply. Divide the grid into yellow regions and brown regions. Each region must consist of orthogonally connected cells, and two regions of the same colour may not share an orthogonal edge. Brown regions (chocolate bars) must be rectangular or square. Yellows regions (bananas) must NOT be square / rectangular. Digits may repeat within regions. A digit in a banana cell indicates exactly how many banana cells contain that digit. A digit in a brown diamond belongs to a chocolate bar and indicates the size of that chocolate bar. Every chocolate bar has a different size. A digit on an arrow cell indicates the total sum of the closest (neighbouring) cells in each of the indicated directions.
