Table for Four - Paint it Black Tetrominos
(Published on 19. August 2014, 12:44 by uvo)
This puzzle is one of four practice puzzles that I created for this years WPC team round "Table for Four". In this round, teams of four players had to solve puzzles in four colours; each player had a coloured pen (red, green, blue, black) and wasn't allowed to write in a different colour. Each puzzle has grid size 9x9, and in each colour 20 cells have to be marked; one cell remains empty. No cell can be marked in more than one colour.
The clues outside the grid apply only for the player with the corresponding colour; the players are seated at four sides of a table, and clues are always orientated towards the player with the corresponding colour.
The rules for each player are:
Place the full set of five different tetrominos into the grid. Tetrominos cannot touch each other, not even diagonally. Tetrominos can be rotated and reflected. Clue numbers outside the grid provide the length of consecutive blocks of tetromino cells in the corresponding columns and rows respectively. The clue numbers are in the correct order and there must be at least one space between blocks.

Solution code: The marked rows from left to right: for each cell the first letter of the corresponding colour (R=Red, G=Green, B=Blue, S=Black [Schwarz]) or X for an empty cell.
