The Incredible Machine 2

This game is an epitome of  what puzzle games should be like. It's about our dream of being Tom or Wile E.Coyote coming up with fantastic contraptions in order to catch their respective prey. You're given parts you need to integrate into a contraption that needs to perform a task (usually moving objects in a wanted direction).A cannon shoots a ball, the ball turns on a switch, the switch sets a factory line in motion and the motion spills a bucket with another ball coming out etc. Sounds simple and maybe a bit too retro as an idea for a game now, but it's another highly addictive game that stood the test of time with its unique concept.The navigation is easy, the playability is extremely high, the icons are beautiful. Of course,  Incredible Machine 1 set the foundation for the entire series, with IM 2 introducing new levels , better graphics ,less irritating sounds,new parts for machines etc, All the later versions  failed to introduce something new and take players somewhere else.

Absolutely worth your time.
