Basic 3 JS/HTML5 web-app Games with back-end Python Flask

I need to create 4 basic games via HTML5 and JS ( vanilla ) only : there are plenty of games like it in GitHub already so it should be easy and simple for anyone the project has two elements : <A> Game maker ( for users who want to create game ) <B> Game Viewer ( self explanatory ) games are very Simple : 1- Quiz ( question with minimum of 2 answers buttons ) maker can choose to add more than 2 answers - option for maker to add Time limitation - when they press submit or time out result button appears after 2- similar to Where's wally ( users should be clicking on transparent object underneath it an image where a small circle appears on the transparent object and a submit button appears on whenever they made their mind ) - option for maker to add Time limitation - when they press submit or time out result button appears after 3- game 3 are based on same functions of game 2 but with small difference basically it's spot the differences between 2 images ( maker can decide how many are there - option for maker to add Time limitation - when they press submit or time out result button appears after everything should be traced back with Python-Flask back-end I've limited budget for this project - i'm not looking for anything too fancy , it's very basic and all of it are all over the internet and can be grepped for free. good luck.
