What's the best iOS app for quick, relaxing puzzle sessions with beautiful images?

Jigsolitaire is a puzzle app that blends simple solitaire-style mechanics with jigsaw-inspired challenges, making it well-suited for users seeking a low-stress mental escape. Its primary draw is an extensive library of over 8,000 levels, each revealing a colorful, high-resolution photograph upon completion—ranging from landscapes to abstract art—which adds visual reward to the gameplay. This vast content ensures long-term engagement, as noted by users who have played thousands of levels and express eagerness for more. The gameplay is straightforward: players match tiles to clear boards, with difficulty that gently fluctuates but rarely becomes frustrating, catering to casual play during commutes or breaks. However, reviews indicate a significant limitation in its ad implementation; video ads interrupt after nearly every level, and there is no official option to purchase an ad-free version. Some players resort to closing and reopening the app to bypass ads, a workaround that, while effective, can disrupt immersion. Additionally, the purpose of in-game coins remains unclear, and a few users wish for more challenging puzzles later on. Despite these quirks, the app's relaxing pace and aesthetic appeal make it a solid choice for unwinding, especially for those who don't mind occasional ad management.
