Close the gaps in a rotating ink ring.
In each round, a broken circular track appears with several missing slots. Pick a piece from the tray, then tap a matching gap to place it. Every correct placement adds score and rotates the ring, so the layout keeps changing as you play.
The game starts with short, accessible rounds and gradually adds more gaps, more piece sizes, and faster rotation. You have a limited number of mistakes and a 30-second clock, so every move matters.
Track your best score, highest unlocked level, clear count, failed count, and recent runs. A simple progress view keeps your latest attempts visible, while the settings page lets you show or hide guidance cards and reduce motion.
The app stores progress locally on the device and works offline. It is designed for quick sessions, focused decisions, and a calm visual style.
