corporative app + tetris similar game

Project. App (initially for iOS and Android) I want an application that consists of three sections: 1- Budget. By introducing a number of parameters, the customer can calculate an estimate, which should always eventually corroborate with the carrier. 2- Geolocation. By entering a code, the client can always know where is his box. 3- Game. Development of a game related to the world of transport and logistics (had thought of something similar to tetris with boxes of different sizes that were filling a truck, whose aim was the optimization of space).
