How do I create tetris clone without arrays?

Its posible create tetris like game without use arrays or other tools that need high iq?

I think it will be easier to create it with arrays and without them, you probably would need to put more thought into it.

But basically: yes, it is possible

All of those "grid style" games like tetris, match3 etc. can be made without arrays and purely "reactive". The problem is, that this gets really bad to maintain really quickly.

Doing it without the abstraction is not really easier. It's easy for some blocks falling down, but as soon as it gets interesting, you want arrays.

If you don't use an array you still will be using the concept of an array or grid. I've made tetris twice and didn't actually use an array.

I found that arrays make a lot of things a lot easier to work with and more organized.

Don't be intimidated... they don't require high IQ. Think of them as spreadsheets you can manipulate with code.

But like others said, it is possible, just might be harder.
