The Tradition
Since launch day, fans have marked the anniversary with fan art marathons, charity streams, soundtrack replays and — always — Gaster puzzles. His ALL-CAPS Wingdings is the game's most iconic visual language, so every September the translators get busy. Encode "Happy Anniversary" above, post the symbols, and let friends decode them at our Gaster translator.
