COUNTLINE

Countline is a focused number-connection puzzle game built for iPhone. Read the rule, find the correct order, and draw a continuous route through every numbered node. Clean decisions, accurate paths, and efficient movement turn a simple sequence into a tactical challenge.

HOW TO PLAY

• Touch the required starting node and drag through the numbers in the correct sequence.
• Keep the route clear of obstacles and follow any directional checkpoints.
• Complete every lane when a puzzle contains two colored paths.
• Avoid crossing an existing path on levels where crossing is disabled.
• Finish quickly and accurately to improve your score, combo, efficiency, and star rating.

CAMPAIGN

The campaign contains 24 handcrafted tracks across four chapters:

1. First Light
2. Cross Current
3. Deep Signal
4. Final Pulse

New tracks unlock as earlier tracks are completed. The campaign develops from direct routes into layered puzzles with hazards, multiple lanes, special nodes, and stricter path planning.

NUMBER RULES

Countline changes the required sequence through several rule types:

• Count Up: connect values in ascending order.
• Reverse: connect values in descending order.
• Odd / Even: resolve odd and even values in the required sequence.
• Skip Count: advance through values by a fixed step.
• Growing Sums: follow an arithmetic pattern with increasing differences.

ROUTE MECHANICS

Obstacles block parts of the board. Directional checkpoints require the route to enter from the indicated direction. Some tracks prevent paths from crossing, while dual-line tracks ask you to complete two independent colored sequences.

SPECIAL NODES

• Hidden nodes conceal their values until revealed by play or a power-up.
• Moving nodes shift position while the puzzle is active.
• Countdown nodes must be reached before their timer expires.
• Switcher nodes can rearrange the board layout.
• Freeze nodes briefly pause timed activity.

GAME MODES

• Zen: a relaxed memory-focused route with hidden numbers and no crossing restriction.
• Rush: timed rounds that reward fast, accurate connections.
• Endless: an evolving sequence of rounds with varied rules and special nodes.
• Daily Track: one date-based challenge with a daily streak to maintain.
• One Stroke: a hard single-drag trial. Releasing early, choosing a wrong node, hitting a barrier, crossing the route, or missing a directional checkpoint immediately fails the attempt.
• Blackout: study the visible sequence before the numbers disappear, then rebuild the route from memory.
• Relay: complete two differently colored number lines on one board without letting the routes cross.

POWER-UPS

• Reveal exposes hidden information.
• Freeze pauses active timed pressure.
• Undo removes the most recent connection step.

Power-ups are earned through strong results and accurate runs. Additional tools unlock as campaign stars are collected.

PROGRESS AND RECORDS

Each run can award score, combo, efficiency, and up to three stars. Countline records campaign bests, recent runs, achievements, power-up inventory, and daily streak progress. The History page provides a local summary of completed play.
