Domino Effect!

Details

This is a puzzle game where you have to manipulate domino that they all fall in a chain reaction according to certain rules. Rules: -All dominos must fall and none must crash into another; -One special domino must fall as last domino and that domino triggers the exit door to open when you enter the exit door the level has been completed; -You may rearrange as many dominos as you want, except for the trigger. You may not place dominos in front of the doors, except for the vanishing domino.; -You may push push once to start a chain reaction with the dominos leading to the fall of all of them; -All this has to be done within a time limit (which is normally generous); -There are 11 different dominos that behave differently when pushed, some fall, some not, some wait a bit before they fall, some raise, some toppler until they meet an obstacle; -There is a help in the game and introductory levels that show how all the dominos work;
