Fun & mind-lifting. ### 5/5 — Fun screw game *2025-07-22* Fun screw game. Enjoying hours of fun and new designs to unscrew objects makes me feel good. ### 3/5 — 色が分かりづらい *2025-07-13* ネジの色がほぼ同じやつがあって分かりづらい。もう少し色を分かりやすく区別してほしい ### 5/5 — My go to *2025-06-25* It’s so relaxing ☺️ ### 5/5 — Unscrew puzzle *2025-06-23* This game can be very challenging. Try it have fun with it I do’ ### 5/5 — Adorable little game! *2025-06-08* This is a very cute game! I love the colors, and it’s hard to put down. ### 3/5 — Colors are hard to distinguish *2025-06-07* It is EXTREMELY hard to tell if the lighter or darker purple is the one to be used for a box. For example: the box is the exact color of the lighter color purple, but takes dark purple instead. App also does not have any color blind options. ### 4/5 — guter Zeitvertreib aber.. *2025-04-27, version 1.21* zu viel Werbung >.> ### 5/5 — Cute! *2025-04-26* I go through the levels so fast I don’t even have time to appreciate how adorable the patterns of the little stained glass style screw plates the game uses. The cities and the little mascots are cute as well. I downloaded this for rewards on another app but I’ve come to really like the game. Normally these types of games are a dime a dozen but the art style is really unique. One of the better ones to come out of this sort of oversaturated genre. Good job dev team! ## Frequently asked questions about Unscrew Puzzle ### What is Screw Puzzle: Pin Jam?
