Game Builder Tutorial 2: Build a Blackjack Card Game (Duke Jack)

Short summary

This tutorial walks through building a blackjack card game called Duke Jack using Codename One's Game Builder in board mode, where cards are grid-placed entities with rank, suit, and faceUp properties. It covers table setup, card rendering via the standard Graphics API, and wiring up complete blackjack rules including hit, stand, dealer draw, and win/lose decisions. The approach demonstrates that the same mature Codename One graphics stack used for UI components works seamlessly for game rendering.
