• You need to stop THE VIRUS, while you still have free cells:
  • It spreads CONTINUOUSLY  from cell to cell;
  • It starts with a random SEQUENCE;
  • Each TURN It just duplicates current strain.
• You can neutralize TWO infected cells by these RULES:
  1. They both should be on the same VERTICAL, HORIZONTAL or DIAGONAL,
  2. They both should be VISIBLE to each other,
  3. They both should have the SAME VALUE or make a SUM OF 10.
• There are also limited powers to EXCHANGE two cells or MOVE one into next free spot
