A map of the world with habitats in red is displayed in the upper part of the screen. Select the appropriate animal from the lower picker view. The done button on the right end of the toolbar at the top of the picker view will confirm your selection.
For correct answers, a success sound is played and the correct count is increased by one. Incorrect answer is a buzzer sound. In either case, an illustration of the correct animal is displayed in the middle of the map, and about 2 seconds later, the next question will be displayed.
When 10 questions are completed, there will be one set. The number of correct answers and the number of questions are indicated by black numbers at the bottom edge of the world map. A brief message is displayed in red according to the percentage of correct answers.
The 36 questions are prepared and shuffled for each set, so you can enjoy the game repeatedly.
