Concept - concept of game is very awesome to play a game more than 1 one player at the same time via Wifi, it is the time passing game, we are playing alomost 3 hours in a day in fact we are also played in exam time.
Layout - Layout of game is so simple and best game even it can play at low graphic phones also play at minimum RAM.
Feature - feature of game is so good, If we want to play game one person will be admin and the on there hotspot and he asked to frnd to join via wifi, when friend will join then admin will chose the time of game and location of game.
Usefulness- if we are taking about usefullness so its is a very usefull for time person trust you dont belive that how the time will pass
Overall I love this Game.
