NCIS: Hidden Crimes walkthrough - Episode 2, Big Bang

You need to finish all the missions presented on the "Episode" tab to complete the case. These often require coins which you can collect by doing trades.

First, tap on "Trade" at the bottom of the screen. You'll see a list of items you need to get for Abby. Tap on Get, and then the glowing area photo.

Then do the hidden object mission with the needed item on the card. Once you have all the things Abby needs, trade the items for coins.

You can also get coins by finishing achievements, and through in-app purchases.

Move the pieces of the bomb detonator to look like this.

Move the CDs to find this red disc.

Drag the detonator at the bottom onto the bomb on the right side of the screen.

This is like Boggle. Trace your finger from letter to letter, to spell out the word on screen. It doesn't always start on the left side: the word could be anywhere.

Drag the sheet music onto the jukebox.

Change between the three magnification settings until you can find the material seen in the top left corner. Wait for the material to float into the open to avoid accidentally tapping a microbe.

Arrest Wade Byer for the murder.
