If you’re looking to expand your mental horizons, this is the game to play! Simple yet challenging. Awesome 5-15min fix. Enjoying it thoroughly! ### 5/5 — Einfach gehalten, dadurch besonders *2024-08-24* Ein klares und minimalistisches Design. Einfach zu verstehen, einfach zu spielen. Die Mechaniken in den verschiedenen Rätseln sind schnell verstanden und die Rätsel sind nicht zu komplex, so dass man mit ein wenig Geduld auch die etwas schwierigeren in angemessener Zeit lösen kann. Ach ja, Zeit hat man soviel man will. Dadurch kann man sich voll auf die Rätsel konzentrieren. Zu Recht ein Finalist im Design Award. Hier sieht man wieder, gute Games für wenig Speicherplatz sind möglich (auch wenn es am Speicherplatz heutzutage nicht mehr scheitern sollte 😅) Preis/Leistung mehr als angemessen! ### 1/5 — Quadline *2024-02-18* This app does not run on my iPad ### 5/5 — Amazing *2022-09-20, version 1.1* It is good app to train your mind ### 5/5 — Beautiful game *2022-09-14, version 1.1* Design and gameplay are awesome 😍 ### 5/5 — Amazing *2022-09-08, version 1.1* This animation is a separate work of art 😍 ### 5/5 — シンプル故に最高です *2022-02-01* 時間制限もなく 運の要素が有るわけでもなく 派手でもなく パズルの基本である「暇つぶし」だけを 見事に体現してる ### 5/5 — Buy It! *2022-01-14* Agreed on previous reviews.
