Start a fight by skipping a turn in order to increase your battle points. Standing your ground on your first turn in a fight is usually a good choice. The extra battle point obtained can be very useful. Always go on the offense. Use all your points into an attack to try to quickly end a fight. CPU opponents rarely use their defenses to neutralize the attack. Certain dinosaurs classes have advantages over others. Carnivores are stronger than herbivores. Herbivores are stronger than pterosaurs. Pterosaurs are stronger than amphibians. Amphibians are stronger than carnivores. You can switch dinosaurs during a battle for one battle point by tapping their portraits (look at the upper left-hand side of the screen). Do this to take advantage of your opponent's weaknesses.
DNA
DNA can be found in card packs. You can get a free pack every six hours. Tap on your DNA total at the top of the main screen, then tap the green "GET IT FREE" button to watch an advertising video to get some DNA in return. Note: This can only be done a few times per day. DNA is rewarded at the end of certain missions. Sell unwanted dinosaurs. Although you will not get as much DNA back by selling a dinosaur as spent on its purchase, you can get rid of unwanted dinosaurs for some DNA.
Food
Keep your food production buildings always working. Your dinosaurs require food to level up, which is important for them to perform well in the arena. Repeatedly queue up food production in ten-minute increments. This eliminates the need go back and forth to your food building.
Money
Level up your dinosaurs to increase their battle performance, which results in money. Leveling up your dinosaurs makes them stronger and gives them the chance to evolve. They will also earn more money when they are being held in their pens. Build structures to generate more money. Also build supplemental structures such as food buildings and security booths for extra income and to improve your park's appearance. Complete special missions quickly before they disappear. Special missions are a good way to earn the dino bucks, the game's premium currency. Watch advertising videos to earn dino bucks. Note: Allow the timer to count down before exiting to make sure you earn your reward.
Mystery packs
Log in every five hours or so to collect a free mystery pack. They contain money, food, special missions, and sometimes the DNA needed to hatch a dinosaur.
