COLOR LINES
The Color Lines Blog
The Color Lines Blog covers two sides of the same game: the strategy that turns a quick five into a record-breaking combo, and the small pathfinding algorithm that quietly decides where every marble is allowed to move.
How to Get a High Score in Color Lines
The free-turn rule, reading the preview, edge-building and crossing combos — the concrete habits that separate a 400 from a 4,000 in Lines 98.

Why a marble sometimes can't reach an empty square, how breadth-first search lights up every reachable cell, and how the same idea powers the Smart-Move hint.
ReadRead them in either order, but they answer different questions. The strategy post is about decisions: when to cash in a line versus hold it for a bigger combo, why edges and corners make better building sites than the open middle, and how to read the next-ball preview so incoming marbles help you instead of blocking your best lane. The pathfinding post is about mechanics: it walks through the breadth-first search that decides, square by square, whether a marble can actually reach where you want to send it, and why that same flood-fill is also what powers the AI Smart-Move hint on the game page.
Neither post assumes you already know Color Lines — each opens with the rule or the mechanic it's explaining before going deeper. If you're brand new to the game, play a round or two first so the strategy advice has something concrete to attach to; the board teaches the free-turn rule faster than any paragraph can.
