How to use the guide: choose the highest-scoring candidate as a starting direction, then watch the score change after each Charleston pass and draw. It identifies useful card families and the tiles to protect; it does not reproduce or claim to be the official annual card.
Your rack · East
Core rules in this build: 152 tiles including 8 Jokers and 8 Flowers; East starts with 14 tiles; the first Charleston is Right → Across → Left; Jokers cannot be passed. After the Charleston, the table moves into draw-and-discard play. Full official card-line validation, calling, scoring and computer play remain separate milestones.
