The Lucky Letterbox debuted during Chinese New Year 2024 (Year of the Dragon) in February 2024. This unique 2×2 red decorative letterbox/mailbox is adorned with dragon motifs, golden accents, and lucky CNY symbols — evoking the tradition of sending red envelopes (hongbao) during the new year. It costs 8,888 Elixir and rewards 88,888 Elixir. The Dragon Year brought extra excitement, and the community praised the creative letterbox concept as a fresh departure from previous lantern or plant-based CNY obstacles. Players called it inventive and culturally fitting, especially celebrating the powerful Dragon Year symbolism that the CoC art team incorporated skillfully.
