Android App Game

Well our Game is very Simple : - it will be Called Perfection and its very Simple but we will use it for a cloth shop where the client after buying with a voucher over 100 $ for example and he will take qode to play the game, and each code will allow him to play once. So we will decide how much each code will be given for maybe 10, 20, 30$ . We wil lfind out later who is the person who finished the game in the fastest time, and who played most and etc.. So we know who will be the winner. -The game concept is a box of 25 small boxes numbered from 1 to 24 and a box is empty. So the numbers are destribtuted in wrong order and the user's goal is to finish the game and reoder the numbers in the right order. so we will be able to count how many moves he did, time he used to finish, and how many times he played.
