Stickman Causality Games
Causality are basically point and click stickman games where the goal for the player is to cause the sequence of events which then results in, most often the brutal death of all stickmen involved in the scene.
It had all started when bored.com made their first causality game which had 3 levels. The action takes place in an office, where workers chat in a relaxed manner, drink their coffees and some even sleep in their work space. By clicking the mouse, your task is to cause the series of 'mishaps' where some workers accidentally fall off the building, others trip and fatally hit their head on the floor, a some are not too lucky to find themselves in the elevator which suddenly unhooks itself. The task is considered successful if all of the participants involved in the scene have died. Scenes usually contain lots of brutality and blood.
After a great success of the first game, fast came other sequels: Causality 2,3,4 ... Causality Halloween Horror, Causality Adventure and others. The action was moved from the office to other places: park, plaza, disco... Bored.com Then hired the same developers to make ClickDeath series which is practically identical to Causality.
Sometimes it is very hard to find the right sequence and that is why people usually search online for terms such as 'cheat codes' and 'causality walkthrough'. Thus the YouTube is littered with hundreds of video walktroughs and there are also loads of textual manuals online as well.
