About this game

Meet the first episode of a famous series of detective games «Who Is The Killer?» called «The Old Sins». You have found yourself being trapped in the castle with seven characters, and one of them is a murderer. Every day one of the charecters is killed, only you can stop the killer.

«We would personally recommend everyone to try this game, especially those who love brain teasers. You’ll love it!» — Gameographics.

— Breathtaking detective gameplay for those who like to think.
— Old mystery background story and atmospheric music.
— Original criminal mini-games and puzzles.

Speak with characters, investigate crime scenes, try to think as a criminal minds, guess who lies, listen your intuition to find clues and arrest the killer before it’s too late! Everyday someone dies and you need to figure out who is the killer using just your logic. It’s a murder mystery game where everybody has a secret of the past. Everybody could have reasons to do this. And you have only seven days to stop the murderer. All mystery case files are very important! Remember it’s not a casual adventure game. There is no happy end in this story, you can even lose the game (if everybody dies).

– The game is based on classical english detective rules in the tradition of Sherlock Holmes. The plot of the game is complicated. Everything is not so obvious at this time, you can find some parallel mystery stories, but only one will lead to the killer.
– Pictures from the scene can be studied with a magnifying glass but this is not a standard hidden object game or puzzle quest, here each piece of evidence is important for further investigation.
– Enjoy a thrilling adventure, explore mystery murder locations, decipher puzzles and gather clues! Do everything that is need to prevent new murders and find the killer!

Terrible app. Basically there is no way you can progress without paying as even if you know the killer you are not able to accuse (because the witnesses you would have to question are blocked). I'm going to remove the app and wouldn't recommend it. Waste of time as when you progress in the level you have to wait a day to realize that it's not possible at the end....

It was a good idea and concept, but is impossible to win for free without getting extra lucky. (I chose someone from the very beginning and stuck with them and even so a couple of deaths happened before I was able to arrest them.) I don't mind the wait between days however the short gameplay might not be worth the wait for most.

Terrible "free" game. You can only play for 10 mins at a time about twice a day without paying. After 5 days of playing you get murdered so you never end up solving it...unless you start over and obviously spend money. Other than that the puzzles and graphics are good. This is not animated at all but that didn't concern me. I was looking for a free murder mystery puzzle game.
