Dive into the world of *Scarlet Girls*, a brand-new, captivating Idle RPG set in the 119th year of the Old Euro Calendar. In this game, humanity teeters on the brink of extinction, threatened by mutated animals and powerful beings. Your mission is to recruit and train an all-girl squad of technologically enhanced mecha waifus, known as "Stellaris," to combat the catastromechs and restore peace to Earth. This beginner's guide will help you understand the core game mechanics and game modes, enhancing your account power and progression. Let's get started!
Understanding the Combat Mechanics of Scarlet Girls
*Scarlet Girls* offers a completely idle-based gameplay experience, perfect for those who prefer a more relaxed approach to gaming. The combat unfolds in a turn-based system, with the sequence of actions determined by the Speed stat of both allies and enemies. Each round concludes once every participant has taken their turn. You can deploy up to five characters into battle, and the game's Quick Dispatch feature automatically arranges your squad based on the strongest characters available. Once your team is set, you can sit back and enjoy the visually stunning animations accompanying each Stellaris's unique abilities.
Your Stellaris characters automatically utilize their active and passive abilities during combat, each with a cooldown timer dictating when they can be used again. The key to success lies in crafting synergistic squads that maximize the strengths of your mecha girls. Although battles occur in real-time, player intervention during the combat phase is minimal, making strategic team composition and character power crucial.

Each Stellaris is categorized into one of four classes, each with specific roles:
- Paladins – Boast the highest armor stat, acting as the frontline to absorb enemy attacks and protect their teammates.
- Support – Specialize in healing and support, offering crucial utility from the backline.
- Devastator – Masters of heavy firepower, designed to deal devastating energy damage to enemies.
- Assaulter – Experts in bladed combat, focusing on inflicting physical damage to dismantle foes.
Echo – The Gacha System of Scarlet Girls
Recruiting Stellaris is facilitated through the game's gacha system, known as "Echo." Stellaris come in varying rarities: R, SR, SSR, and SSR+, with higher rarity characters possessing stronger base stats and more powerful abilities, pivotal for turning the tide of battle.
At the game's global launch, the "Normal Echo" banner is available, offering R to SSR Stellaris. Players can summon using Echo tickets or Diamonds, with an SSR character guaranteed within 40 summons. Each summon on the banner also earns you 20 echo points, and accumulating 2000 points allows you to summon a random SSR character from one of the four elemental banners (excluding Nebula). You can track your progress on the right-hand side of the Echo system. The recruitment probabilities are as follows:
- R Stellaris – 19.979% chance per character
- SR Stellaris – 2.667% chance per character
- SSR Stellaris – 0.133% chance per character
- SSR+ Stellaris – 0.010% chance per character
For an enhanced gaming experience, consider playing *Scarlet Girls* on your PC or laptop using BlueStacks. Enjoy the game on a larger screen with the precision of a keyboard and mouse to fully immerse yourself in the action.
