Make unity online game

I've built a website before.

This site is a game site and it is played first as a number puzzle and then as a word puzzle.

Hence the name: one word, one operation.

However, it was a webview site and some parts did not work properly.

That's why I want to make a similar one again.

There are 5 buttons in the game.

1- Play for points
2- Play for coins
3- Play with opponent
4- Play with lots of opponents
5- wheel of luck

The friend who will do this job should take care of everything, including design.
