More Bolleke Puzzles

Last weekend I found two more Bolleke Puzzles. Rules for solving Bolleke Puzzles are certainly simpler than Sudoku.
1. Each row/column contains ten balls, five open and five solid balls.
2. Not more than two of the same balls (open or closed) may be next to each other horizontally and vertically.
That's all. Here are the
first and second Bolleke Puzzles I posted and their Solution (one and two).
I requested De Koninck to send me the total number of Bolleke puzzles, until then I am not sure I've collected all Bolleke Puzzles.

UPDATE : Solution Bolleke Puzzle 3 and 4.
