Idle Gladiator Arena

This is a portrait-oriented idle clicker game that can be played solo with short, frequent sessions, making it highly interruptible and suitable for one-handed play. While it offers high replay value and can be played offline, progression is heavily reliant on watching ads or making in-app purchases, often leading to a pay-to-win experience. It's best suited for players looking for a mindless, casual time-killer that doesn't require significant attention or investment.
