In Crime Scene you have to find clues and solve crimes. Expand your police station with up to eight different officers, and use their various abilities to complete as many missions as you can. Collect donuts, upgrade your officers and fill the criminal album which is updated with new criminals every month.
You can play missions on three different levels of difficulty, and set a personal record for each level of difficulty. The higher the difficulty level you choose, the more suspects there are and the bigger the level. The reward for completing the mission also depends on the degree of difficulty. When you play a mission, you are introduced to a number of suspects. It is your job to find out who the culprit is by excluding those who are innocent. You do this by searching for clues. You have a limited number of searches, so use them wisely.
There are three types of clues:
If you find e.g. proof that a suspect is impatient, and later an alibi that says the criminal is NOT impatient, then you can exclude the suspect. Tap the suspect you want to exclude. If you have excluded all but one suspect, then you know who the criminal is. Then press the magnifying glass to complete the mission. If you can not exclude all suspects, you have to guess. The game will then tell you if you have guessed correctly.
In your notebook you will find an overview of all the clues you have found. You can also use the buttons in the notebook to exclude and charge the suspects.
In the game there are eight different officers. From the start, you only have access to Mathias. They each have different abilities:
The various officers can also be upgraded up to level 5. This will make them significantly better. Eg. Mathias will have as much as 25% more searches at level 5, thus making it easier for you to reach higher and harder rounds.
To unlock more officers, and to upgrade them, use donuts. You win donuts by completing missions. A normal mission gives 5 donuts, a practice mission gives 15 and expert missions give 25 donuts. In addition, you get extra donuts corresponding to how many searches you have left. If you lose a mission, you lose a similar number of donuts.
You can also buy donuts in the game's shop, find up to 30 donuts and get donuts to achieve the game's distinctions.
Each month you will receive an honor in bronze, silver or gold depending on how many criminals from the criminal album you have captured. The more of the criminals you have caught, the more donuts you will be rewarded with. A filled criminal album is rewarded with 1,000 donuts.
You will also receive honors for missions completed with each officer. For 25 missions completed you get 100 donuts, for 100 missions you get 250 donuts and for 500 missions completed you get 1,000 donuts.
