Fantastic contraption and Tinkerball are both fun games, but the both are different so we are going to compare and contrast. Tinker ball is a game where you can make a design and try to get the ball in the cup. Each level get's harder and the cup keeps moving around so that you can try out different design's. Fantastic contraption is kind of the same thing. You get to make a design, but you have to make a car type thing and you have to get the car type thing into this red zone that say's goal. If you get into the red zone than you will go to next level. For fantastic contraption the very first thing that you will see is a screen that say's places like START HERE,Reach Up,Junkyard,on a roll, and a bunch of other places that you can go to. You will also see thing's that say My Designs,Player Levels,New level, and my level's. The last thing that you will see is Sign In,New User, and a pink cloud with word's in it that is asking you to support this website. Tinker ball has a page where you don't have alot of of places to go. Really you have no place to go unless you click PLAY NOW and that will take you to the game. You have 15 things to choose from. You have 2 cans,2 gears,2 funnels,2 tubes,1 bat,1 hockey stick,2 springs,1 hammer, and 2 pieces of wood that can move around. They are kind of the same thing. You can design things and you get to see them work. These games are the same in ways. I really like these games and I hope that you like them to.
