Doesn't allow users to stop. Purposely addictive.
There is no such thing as coming to a good stopping place in King of Thieves, or pressing pause. If you leave in the middle of your session all your work since the last achievement (a robbery no less, so the player is playing at being a criminal) is lost. This means that when a parent asks a child to stop, the urgency of refusing to stop is extreme and the anger and tears at being forced to lose ten minutes or thirty minutes of work, possibly the whole session wasted, come out of nowhere, creating temper tantrums where there were none before. For this reason, because you can't just stop and pick it up again later without losing significant amounts of spent effort, I have deleted the game from our tablet and will not allow my children to play it again. King of Thieves has ruined our sweet little boy and turned him into a raging, screaming, door slamming, sobbing addict. It is truly terrifying.
