Guild Master - Idle Dungeons

This is a solo, idle RPG designed for short, interruptible sessions, playable one-handed in portrait mode. While progression can be slow, it offers a fair freemium model with no forced ads and is suitable for players seeking a relaxing, low-demand experience they can check in on throughout the day. Its offline playability and high replay value make it a good fit for casual players or those who enjoy long-term progression without intense engagement.
