Solve compact grid-based logic routes in short, focused sessions.

Each puzzle starts with a brief loading sequence and then presents a 5x5 board.
Tap the entry tile, follow adjacent tiles, and respect the active ascending or descending rule.
Every board includes a step limit, blocked tiles, and a visible goal tile so each run feels deliberate and readable.

Use hints when you want a quick nudge, reset the current route at any time, or move on to the next level after a successful solve.
Recent runs help you review outcomes, while score and streak tracking add a light sense of progression without requiring an account or network access.

The experience is designed for offline play, fast retries, and clear feedback.
It focuses on simple controls, readable states, and puzzle flow that works well on Android phones and tablets.
