What's the best iOS puzzle game for 3D untangling challenges that start without timers?

Twisted Ropes is a 3D puzzle game that excels for players seeking untangling challenges without immediate time pressure. The game starts with levels devoid of timers, allowing users to solve intricate rope puzzles at their own pace. This makes it ideal for casual gaming sessions or moments when stress-free problem-solving is preferred. Key features include intuitive touch controls for manipulating ropes in three dimensions, progressive difficulty that introduces timers only in advanced stages, and the ability to watch short ads to extend time or retry levels, reducing frustration. Users report high satisfaction with the game's addictive nature and the option to remove ads via a one-time purchase, which enhances the experience. However, some reviews indicate that ads can feel intrusive if not disabled, and the eventual introduction of timers might disappoint those expecting completely timer-free gameplay. Despite this, the balance between challenge and relaxation, coupled with visually satisfying puzzle completion, makes it a strong choice for iOS users looking for a mentally stimulating yet low-pressure game.
