究極のモンスター集め is an iPhone game developed by yoshiteru oyanagi. In this game, your goal is to complete the monster encyclopedia by hatching eggs and collecting creatures. Each egg contains a creature with a unique voice. To hatch the eggs, you need to choose the correct answer from the options A to E. The correct answer will crack the egg and reveal the creature inside. However, one of the options is incorrect, so you need to guess carefully. As your score increases, cracks will appear on the eggs.

To help you hatch the eggs, there are special items available. These items can be obtained by catching shooting stars on the screen. There are three types of items: yellow shooting star, blue shooting star, and heart. The yellow shooting star increases your score by 2 points for 1 to 5 turns. The blue shooting star increases your score by 3 points for 5 turns, and it can be exchanged for 3 yellow shooting stars. The heart restores one life, up to a maximum of 2, and it can be exchanged for 5 yellow shooting stars.

Each monster has its own unique skill, and it's up to you to decide when and how to use the items. Use your wits and strategy to collect all the monsters in the game's ultimate challenge.

Can you complete the monster encyclopedia and become the ultimate monster collector?
