Hi,

I've been producing a Connect 4 App in Outsystems, that is based on the logic I used in C# as I can't do screen work in C# yet.

It all works, however, it's a bit slow. (A couple of seconds to make a move). Each class, is a separate module and all the logic, to create the grid, save the grid, check if there is a horizontal, vertical or diagonal match is all performed as client actions as I read that was quicker. Weirdly, I've also read "heavy" logic should be on the Server but you should limit interactions with the server. I am also using Client Variables to store the grid, no of columns, rows, the current player etc.

Do I need to transfer some of the logic into Server side logic, instead of client side logic? If so, if it uses client variables, should I use site properties instead?

Is there a rule saying when an action should be client side, and when one should be server side? 

Is having all the different logic in different modules a good idea, ie a module per class.

I have attached a screenshot that shows "my most complex" client side action.
