Inspection Game : Track and kill the virus

Virus was infected in an isolated place with few blocks in a circular fashion. Once a block is infected, the virus will move to any of its neighbouring blocks upon tracing. Newer technology helps in finding the distance of the virus from the inspected block. This would lead to multiple possibilities and hence the player has to select the tiles wisely. For making the thought process easy for the player, all logically possible locations of the virus are highlighted in red. Virus will move accordingly to make its tracking as difficult as possible. Using some tactics, the virus can be isolated to a single tile. Then the only thing remaining is to eliminate it from existence by tapping on that tile.
