Rescue Girl is a pull-logic puzzle game with adventure elements. Players direct a female knight to find hidden treasure and rescue kidnapped boys in dungeons in over a hundred locations across three geographical regions.
The player must use deductive reasoning to determine the correct order to remove pin-like metal bars from diagonal, horizontal, and vertical locations to release the treasure or kidnapped boy to the knight from the level higher. However, every level has deadly obstacles, including blue gas, hot lava, and red demons. Players must pull the pins in the correct order to block or destroy one or more obstacles. For example, to protect the knight from lava, the player must pull a pin to drop water into the lava and create rocks.
Rescue Girl rewards players with coins that they can use to change the female knight's clothing, armor, hair color, and style. If players want to multiply their reward by 10, they just need to watch an ad.
The game also has daily rewards and side quests. After the player completes a certain number of levels, they play out scenes where the knight must trick the enemy with one of two possible solutions for each interaction. If they win, they will receive a free item from the spinning wheel. If they make the wrong choice, they will lose one of their red hearts.
