Internationalization puzzles – or how to gamify a training.
summary
A gamified set of programming exercises lives at i18n-puzzles.com and already contains 9 puzzles used in a 10–15 person internal workshop that repeatedly succeeds at giving juniors and seniors confidence. Problems include SMS vs character/byte limits (UTF‑8 vs Java’s UTF‑16 strings and surrogate pairs), a time‑matching puzzle solved with Java Instant and ZoneDateTime, and a real audit‑fixer bug; puzzles run with large inputs, immediate automated answers, a leaderboard, and are public and effective.
