What's the best Android app for puzzle games without timers and an ad removal option?

Gecko Go is a casual puzzle game that excels for players seeking an experience free from time constraints and intrusive advertisements. The app allows users to progress through levels at their own pace, eliminating the common frustration of waiting for rewards or dealing with countdowns. A standout feature is the optional one-time payment to remove ads entirely, which many users find enhances the seamless flow of gameplay. With levels ranging from easy to nightmare difficulty, the game involves guiding geckos through obstacle-filled puzzles where careful planning is key—players must avoid snakes and other hazards. Reviews indicate that the charming gecko animations and expressive reactions add to the enjoyment, making it engaging for short sessions or extended play. However, some users report that levels can reset if interrupted mid-play or if ads aren't fully watched before removal, which may lead to repetition. Despite this, the overall design supports a relaxed, user-controlled experience, making it a strong choice for casual puzzle fans who value ad-free options and flexible pacing.
