Criminal Case: Pacific Bay is a hidden object game that sets you as a detective in the Pacific Bay Police Department investigating crimes in the city. Here's a guide to getting started:

Gameplay and mechanics:
The game starts with a tutorial and requires you to solve a murder case by collecting hidden objects and evidence. As you progress, you'll encounter a series of crimes and investigations that require you to gather clues by searching for items in various scenes. You have a limited amount of energy that is depleted every time you go on an investigation; it replenishes slowly over time or by spending real money. There are also in-game currencies, coins, and cash that you can use to buy hints or helpful items, like a magnifying glass or flashlight that helps you see hidden objects better.

Investigating Crime Scenes:
The game involves investigating crime scenes by searching for clues and hidden objects. You have a limited amount of time to solve each crime scene, and you'll be awarded stars based on how quickly you can find the items. To collect hidden objects, tap on them on the screen. Some items may be blocked by other objects, and you'll need to move certain objects out of the way to uncover hidden ones. Once you find all of the hidden objects, you'll need to tap on the evidence on the right side of the screen to collect and add it to your inventory. Additionally, you will have to search for fingerprints, blood samples, DNA samples, and other pieces of evidence left behind by the perpetrator. You can use coins to buy additional hints that can help you find missing evidence and get more stars.
