Line Graph Quest

Line Graph Quest is a one-stroke line puzzle game built around shape reading, route planning, and precision dragging.

Core Gameplay

Players read a short prompt, start from the required node, and drag through every connected line without lifting the finger. A level is cleared only when every required connection is used exactly once.

The game becomes more difficult as players advance. Later levels add directed arrow lines, ordered checkpoints, shorter target times, mistake limits, combo goals, and optional contract challenges.

Main Features

1. One-Stroke Drag Controls

The game is controlled by dragging through graph nodes. The player must keep the route connected and avoid reusing the same line.

1. Direction-Based Lines

Some lines show arrows. These lines must be drawn in the displayed direction. Drawing them backward causes the attempt to fail.

1. Checkpoint Routes

Purple checkpoint markers must be reached in order. A completed checkpoint may be revisited, but future checkpoints cannot be skipped.

1. Lives, Score, Stars, and Points

Mistakes reduce lives. Successful clears award score, stars, and points based on performance. Points are used for in-game tool upgrades and are not a real-money currency.

1. Tools

Hint, Undo, Guard, and Trace tools help players recover from difficult routes. Some challenge goals reward players for clearing without tools.

1. Daily Challenge

The Daily Challenge selects a level for the day and rewards consistent play with bonus points and streak progress.

1. Contracts

Contracts are stricter challenge variants of existing levels. They add stronger requirements such as no tools, no mistakes, reduced target time, and high combo goals.

1. Records and Achievements

The game stores recent clear records, best scores, stars, points earned, and achievement progress locally on the device.

Audio and Haptics

The game includes background music, click sounds, success and failure sounds, and optional vibration feedback. These can be controlled in the Settings screen.
