LOST opens pop-up stores from time to time, appearing in the form of limited themes, and setting up theme games in shopping malls on different festivals, such as Lunar New Year, Easter, summer vacation, Halloween, Christmas. LOST Pop-Up can drive the flow of people in the mall and stimulate consumption. In the past, LOST has collaborated with many brands to tailor make escape room games, allowing customers to have a unique experience. From a business perspective, there is an ROX (Return of Experience) in addition to ROI (Return of Investment). Therefore, LOST also cooperates with different hotels to change a hotel room into an escape room.
LOST 不定期開設pop up店，以期間限定主題形式出現，在不同的節日於商場設置主題遊戲例如在農曆新年、復活節、暑假、萬聖節、聖誕節，可以為商場帶動人流亦可以刺激消費。LOST 過往聯乘不少品牌出現在密室逃脫遊戲，讓客戶有更加深的體驗。從商業角度來說，ROI (Return of Investment) 之外還要有 ROX (Return of Experience) 。故此LOST亦有跟不同酒店合作，將酒店房間打造成為密室主題，一個不一樣的體驗，遊戲也可以為不同組合定制，無論大小朋友也有一種嶄新的娛樂體驗。
