Joomla 3x game component/module/plugin

Hello I would like a very small Joomla 3 game component/module/plugin, or whatever it needs to complete my request. The component must do this: - when a user play a game on the site, he will earn some points or some prizes, in his treasure chest. (ONLY 1 game! - scratch game) From admin area, I will be able to add the prizes or the points for a particular period. Thank you
