When you catch a prey, you gain catch points (CP) and when you catch a predator you lose health points (HP). \n5. When you explore an empty square, coordinates are printed: \n   The positive number signifies the amount of prey around. \n   The negative number signifies the number of predators around. \n6. If you lose all your HP, you lose. If you catch all of the prey (a target number that is printed at various times during the game), you win. \n7.
