Is there a good iOS app that provides challenging puzzle levels without requiring in-app purchases to advance?

Wood Out is a color-matching exit puzzle game that addresses a common frustration in mobile gaming: levels that become unbeatable without spending money. The core gameplay involves sliding wooden blocks to match colors and clear paths, with each level designed to be solvable through logic and patience. Users report that the puzzle difficulty escalates gradually, providing a sense of accomplishment without the abrupt spikes that often lead to paywalls. A key feature is the absence of forced microtransactions; while the game offers optional purchases for cosmetics or hints, reviews indicate that progress is never blocked by them. This makes it suitable for players seeking a rewarding experience without financial pressure. However, some feedback points to misleading advertisements regarding time limits, with players noting that promotional claims of 'no time limit' don't always align with in-game timers for certain modes. Despite this, the ad experience during gameplay is generally minimal, contributing to uninterrupted sessions. The level design, with over 160 stages at the time of writing, ensures variety and keeps the challenge engaging. For anyone tired of puzzle games that gate progress behind purchases, Wood Out offers a reliable alternative with solid mechanics and a respectful approach to player time.
