User Comments

• “It’s a very good game. Please add more mini-games, dual types, habitats, and monster deletion/storage. Also, make the egg hatchery purchasable.”

• “I like this game because I saw an ad and decided to try it. I installed it and will give it 5 stars—the monsters look cool and the graphics are great. The only issue is that you need to buy monsters using gems, and I don’t have enough, even though I have a lot of gems. Please allow monsters to be purchased with money instead. Otherwise it’s super—thanks for improving the money options and display.”



• “It’s an amazing game. The tournaments are awesome! You can get rare sharks like Megaladon and even a killer whale. You also give bonus magic monsters. You can fuse your monsters and they don’t disappear. Please add more monsters and let players buy another breeding area.”
