What's the best Android app for casual idle gameplay with minimal ads?

Idle Weapon Shop is a well-designed idle simulation game that excels in offering a stress-free gaming experience with minimal advertising interruptions. Players manage a virtual weapon shop, where they can craft, upgrade, and sell weapons through automated systems that progress even when the app is closed. This makes it suitable for casual gamers who want to check in periodically without constant engagement. Key features include an optional ad system that rewards players with bonuses only if they choose to watch, diverse gameplay sections like PvP challenges with unique background music, and straightforward upgrade paths that are easy to follow. Users report appreciating the lack of forced ads, which allows for uninterrupted play, and the variety of activities keeps the experience fresh. However, some reviews indicate a persistent bug where PvP music continues playing after returning to the main menu, which can be distracting. Overall, the game balances depth and accessibility, though the pace might feel slow for those seeking rapid progression. With its focus on optional monetization and engaging mechanics, Idle Weapon Shop stands out for anyone seeking a low-pressure idle game.
