Hidden Fruit (Posted on 2010-05-21) Difficulty: 2 of 5
Some cherries are hidden under the 6x6 grid shown below. The numbers on the grid specify how many cherries lie under the four orthogonally adjacent cells to each given number. There can be only one cherry (or none) in any given position of the grid, and remember the number shown does not count its own cherry, if any, nor the diagonally adjacent positions.

  
2 1 1 2 1 2
1 3 3 2 3 1
2 3 2 2 3 2
2 1 3 2 1 2
1 3 1 1 2 2
1 2 1 1 1 1

Where are the cherries?

The key phrase is "does not count its own cherry, if any, nor the diagonally adjacent positions".  This means that any cherry can affect the value of only those cells with the opposite parity.  If diagonals or the cell under the number were included, then I would not have been able to split the grid by parity.
