Chalk Line: One Stroke

Remember doodling on the classroom blackboard during recess? Chalk Line captures that nostalgic feeling in a brain-teasing one-stroke drawing puzzle. Your task is elegantly simple: connect every dot on the board with a single, unbroken chalk line — never lifting your finger, never visiting the same dot twice.

Chalk Line brings the classic "draw in one stroke" puzzle to life with a handcrafted chalkboard aesthetic. Every line you draw appears as glowing white chalk on a deep green blackboard, complete with subtle texture, chalk dust particles, and the satisfying scratch of chalk against slate.

FEATURES:

• 50 HAND-DESIGNED PUZZLES across four difficulty tiers — from simple 4-dot warm-ups to mind-bending 20-dot expert challenges that require careful planning and spatial reasoning.

• AUTHENTIC CHALKBOARD AESTHETIC — The entire game is rendered on a textured green blackboard surface. Lines appear as soft white chalk with realistic texture overlays. Subtle smudges and imperfections give each board character. Floating chalk dust particles add atmosphere.

• ONE-STROKE GAMEPLAY — Start from any dot and drag your finger to connect dots one by one. The line must pass through every dot exactly once. If you hit a dead end, use UNDO to backtrack and try a different route.

• REQUIRED PATHS — In advanced levels, some connections between dots are marked with faint yellow chalk arrows. These are required paths — your line must include these specific connections, adding an extra layer of strategic planning.

• THREE POWER-UPS:
- Hint: Reveals which dot to connect to next in the solution.
- Peek: Briefly displays the complete solution path for 2 seconds.
- Solve: Automatically completes the puzzle by drawing the full solution.
All power-ups require watching a short video.

• REAL-TIME CHALK RENDERING — As you drag your finger, the chalk line follows your movement with a slight texture delay, simulating the physical sensation of drawing on a board. Each dot lights up yellow as you connect it.

• PROGRESSIVE DIFFICULTY — The puzzle complexity scales naturally:
- Easy: 4-6 dots on a small grid (perfect for learning)
- Medium: 7-10 dots with more possible paths
- Hard: 11-15 dots with required path constraints
- Expert: 16-20 dots requiring careful route planning

• HANDWRITING-STYLE TYPOGRAPHY — All text uses a casual handwriting font that matches the classroom blackboard theme. Dot numbers are written in chalk style.

• SATISFYING AUDIO — Chalk scratch sounds accompany your drawing, with ascending pitch tones as you connect more dots. Completion triggers a celebratory chime sequence.

• NO TIME LIMITS — One-stroke puzzles are about contemplation, not speed. Take your time, study the dot pattern, plan your route, and execute at your own pace.

Chalk Line is perfect for fans of logic puzzles, drawing games, and brain teasers who appreciate a distinctive visual style. Each puzzle is a self-contained challenge that can be solved in minutes but will keep you thinking for hours.
