在遙遠的語文世界裡，每一個正確的中文字都蘊藏着守護知識的光芒。 可是有一天，錯別字魔物從黑暗的裂縫中湧現，牠們悄悄改寫書本、告示與孩子們的記憶，令熟悉的字形變得模糊，令清晰的句子失去力量。 為了阻止混亂擴散，正字戰隊在秘密基地集結。隊員們必須冷靜觀察每一道題目，選出真正正確的中文字，把文字的光芒化成攻擊，擊退潛伏各地的魔物。 每一次答對，都是一次守護語文世界的小勝利；每一次出發，都是向知識與勇氣邁進的一步。 五位正字戰隊的成員！身穿五彩緊身衣，腳踏巨大機械人，誓將所有錯字魔物消滅！ 趕快收集傳說中的武器、練成傳說中的絕技、戰鬥吧！年輕人！ ＊「正字戰隊」是一個以正字為主題，寓學習於娛樂的教育軟件，讓玩家可以在輕鬆愉快（或許是緊張刺激才對）的氣氛下學習不同詞語的正確寫法，減少錯別字，增強語文能力。
