Flagging

In the computer game Minesweeper, the player has an option to flag a square. By doing so, you mark a square with a flag. This is helpful for the player to flag a square that is a mine square as this prevents the player from clicking on the flagged square.
We incorporate this feature of flagging in Colisweeper too. The player has an option to flag a colony. To do this, the the flagging solution is pipetted on to a colony. If the colony turns in to green color , the colony has been flagged. To see more about playing see this. The colony turns green due to the genomic hydrolase lacZ present in mines and non-mine colonies.
