Gearworks! The most amazing part of the game are the sparks and how you acquire them. When you play a gear card onto the grid, you then can start mathing stuff out. Whenever a combination of adjacent cards add up or subtract to your card value, you immediately get one. They can be used for additional actions on your turn like getting new cards or reentering the game once you've passed. This simple mechanism makes the game even a multitude of times more interesting than already was. So you when you didn't get the parts you were looking for, maybe draw another contraption? This could be beneficial, since you only get to score the parts that you receive at the end of the round. Rounded off with interesting asymmetrical character abilities the game definately will stay on my shelf.
