question

How hard is it to program something exactly like this? (poker game)

Wrong question. You should be asking “Can I?” at each step of the way.

Imphenzia: How Did I Learn To Make Games:

This is software engineering. Break the problem down.

Ask yourself “Can I make something that lets deal cards to any specific spot onscreen?”

When you have a deck of cards and they can be dealt out to wherever you tap onscreen, come back and post more questions.

if you have to ask how hard a game is, you are (probably) not ready to make it.

Thanks, I’m just starting out and I’d like to know what I’m up against
That’s why I ask, but thank you very much
have a nice day

A game like that is probably a decent goal for a beginner because the scope is constrained.

But a multiplayer game is harder, so it’s advisable to hold off on that until you’ve got some more experience.

Follow Kurt’s advice to break it down into smaller bits.

very hard if online for multiplayer

very easy if offline single player
