To play, you have to move the various shapes into a working machine to get the ball from the top of the screen to the bottom. The ball has to make it through the machine and hit the bottom crescent to pass the level. This game can be played against the app by yourself. This app helps me to understand Rube Goldberg machines because it shows how much force and what simple machines can be used to get the gall to the end. I give this five stars because it’s fun to play but it also is educational because it can teach students how Rube Goldberg machines work.

I really like this game. It’s an awesome brain teaser and becomes more challenging as the game goes on. This games is relatively new, it would seem but it is addictive and I am excited to see where it goes! I do recommend adding an option to review the game, in app but other than that, i have zero complaints! As with most other games, there are ads that will pop up but i have noticed that the ads are VERY short and i can appreciate that because nothing is more annoying than ads. Overall, great game!
