Play Kero Kero 7 (J) Online

Kero Kero 7 is a 2006 Nintendo DS puzzle platformer from Namco Bandai Games. It arrived during a period when the DS library was filling with quirky, stylized games that made use of the touch screen in inventive ways. This one fits right in with its cheerful, offbeat aesthetic and simple, tactile premise.

You control a round frog, guiding it through a series of single-screen puzzle rooms by drawing paths on the touch screen for it to bounce along. The main goal is to get the frog to the exit in each stage, but you have to figure out the correct trajectory and timing to hit switches, avoid obstacles, and collect the seven star pieces scattered throughout the levels. The mechanics are built around this drawing and bouncing; you need to judge angles and ricochets carefully, and later puzzles introduce elements like moving platforms and enemies that force quick redraws. The difficulty ramps up steadily, demanding more precision and foresight without becoming punishing. It feels like solving a playful physics toybox with your own hand.
