If I want to produce a card game just like UNO, does it better for me to pass the cards into several “Sprites” and set different functions for each cards?
Or do you have any good suggestions for me to develop this game?
Thank you very much!!
all depends on the size of the device targetting… but probably a base card, and lots of card symbols.
Do be aware that UNO is copyright mattel.
Yes, Certainly, my game is not for sale.
I would like to catch the skill only.
What is the differences between large device and small device?
My target is common color mobile phone.
lmao, ain’t that a joke! 
If you mean common as in standard,
then sadly no such thing exists 
So long as you keep it simply however, porting shouldn’t be too much of a problem, emphasis on the shouldn’t 
common color phone is probably the Nokia series 40.
This means 64kB jar, 20kB RMS, ~200 kB heap, no sockets, midp 1.0, 12896 - 12bit colors (128128 with Nokia UI)
