For years this game was listed under the title Block Fiber, with Katakana ブロック・ファイバー, [romaji: burokku fuaibā (fuai-ba or fuai-va)]. It was later determined that both the English and Katakana names are in error, but not before these errors were copied by other sites. It seems most likely that no such 'Block Fiber' game exists, and that the game is Block Fever. The name has been updated. And the Katakana, taken directly from a Japanese language flyer, has been updated to ブロック・フィーバー [romaji: burokku (block) and fuībā (fe-va or fever)].

Katakana is a Japanese phonetic alphabet typically used to write words of foreign origin, like English words. Romaji is the system for writing Japanese phonetics with Romanized characters. The dot in the middle of the Katakana doesn't appear on the flyer. The interpunct ・ (中黒, nakaguro, "middle black") or "katakana middle dot" (as the Unicode consortium calls it) is a small dot used for inter-word separation, and often used for clarity to separate foreign (non-Japanese) words.
