I had worked on many 2D cards game like rummy, poker, teen-Patti, call break and other Casio games, board games like sudoku, chess, snake and ladder, ludo, bingo. Also worked for 3D games like 8 ball,9 ball pool multiplayer with photon and made cricket multiplayer, table-tennis with socket IO.
I have much experience in making multiplayer card games with unity and node js and that it is also for real money game apps.
