Is there a good Android app for an idle game that makes watching ads feel like a choice rather than a chore?

Last Stronghold is an idle survival game that stands out for its approach to ad integration, treating it as a beneficial feature rather than a nuisance. In this title, players build and defend a stronghold with minimal active input, typical of idle genres. Ads are tied to resource pickups and bonuses, offering players the option to watch short videos—often 6 seconds, but sometimes up to 90 seconds—in exchange for items like resource boxes or speed boosts. This system allows for smoother progression, as users can stock up on boosts from the resource menu, reducing frequent ad prompts. Reviews indicate that many find this rewarding, with one user noting the game 'doesn't bog me down with them' due to the tangible benefits. The gameplay itself is engaging, with bright colors, simple character designs, and straightforward mechanics suitable for casual sessions. However, there are limitations: longer ads can lead to disengagement, and some players report update delays, leaving them waiting for new content after completing levels. Despite this, the 4.4 rating reflects a generally positive reception, making it a solid choice for those seeking an idle experience where ads feel optional and worthwhile. It's best for short, relaxed play, balancing ad rewards with enjoyable survival elements.
