Play Daily Killer Sudoku levels. Fill the grid with the numbers 1 to 9, such that each row, column and box contains each number only once. Additionally, a Killer Sudoku grid is divided into cages, each cage has its own background color. The values of the cells in a cage must sum up to the total for that cage, shown in the cage's top left corner. The same number cannot appear in a cage more than once.
Place one by one the 25 robots (randomly selected from 6 each with values 0 to 5) on the board. Scoring is per line (horizontally or vertically). Single robots count their value. Two identical robots in a line count 10 times the value. Any three identical robots in a line count 100. The lowest scoring line (horizontally or vertically) is your score for a level.
