Why do edges and corners help in Lines 98?

A marble in the open middle of the board can extend a line in four directions, which sounds good but actually scatters your effort and leaves your half-built lines easy to block. Marbles on an edge have fewer directions to manage, and a corner anchors a line cleanly. Building along the top, bottom and side rows keeps your structures compact, predictable, and out of the way of the transit lanes you need for moving other marbles.

How important is the next-ball preview?

It is the difference between guessing and planning. The preview shows the three marbles that will drop after your next non-clearing move, and Color Lines also previews their landing squares as small ghost markers. Use it twice: first to avoid moving a marble onto a square a new one is about to take, and second to invest early — if a color you are collecting is coming, start clearing space for it now so the new marbles slot straight into a growing line.

How to Win Color Lines and Score High

Q: When should I just clear a line of five?

Clear immediately when space is running low — once much more than half the board is full, an extra clear that frees five squares is worth more than the points you would gain by holding out. Also clear right away if the path to extend the line is about to be blocked by an incoming marble. The rest of the time, hold: a patient player routinely turns fives into sevens and eights and scores several times more over a full game.

Q: Can I see which squares a marble can reach?

Yes. Tick the Show moves checkbox under the board and, whenever you pick up a marble, every square it can currently reach along a clear path lights up with a small dot. It is an optional aid that is off by default, so the standard game keeps the full Lines 98 challenge of judging reachability yourself. The highlighted squares are exactly the ones the move is allowed to use: a marble travels only through connected empty squares, never over another marble or through a diagonal pinch. Turning Show moves on does not change the rules or make any extra square reachable — it just visualises the paths the game already enforces, which helps while you learn the board or plan a longer route. Leave it off once you have the feel for clear paths and want a cleaner board.

Color Lines — a modern take on the classic puzzle better known as Lines 98 — looks simple: slide marbles into rows of five and they vanish. But the gap between a 400 and a 4,000 is pure strategy. Here is how the best players keep the board open and turn modest fives into board-clearing combos.

The one rule that changes everything

Clearing a line is a free turn — when you complete five or more in a row, no new marbles drop. That single fact rewrites how you should play. A line of exactly five scores 10 points; a line of seven scores 18; a move that completes two crossing lines stacks both. Since holding a line one more turn costs you nothing but a little space, the entire game becomes a question of how long you can patiently extend a line before you are forced to cash it in.

Beginners clear the instant they hit five and wonder why the board keeps filling. Strong players build several four-in-a-row positions across different colors and only complete one when space gets tight — squeezing sixes, sevens and eights out of the same effort.

Read the next-ball preview every single move

The status bar shows the three marbles dropping after your next non-clearing move, and the board previews their landing squares as faint ghost markers. Use that information two ways:

Defend: never move a marble onto a square a new marble is about to occupy, and avoid plugging the lane you will need next turn.
Invest: if a color you are already collecting is in the preview, clear a slot for it now so the new marble lands directly into a growing line instead of scattering.

The board's colors also tend to rotate, so the more of one color you already see, the more you should commit to building that color into a line.

Work the edges and corners

A marble in the open center can extend in four directions — which sounds powerful but actually splits your attention and leaves half-built lines exposed to blocking. Edges have fewer directions to manage and corners anchor a line cleanly. Building along the top, bottom and side rows keeps your structures compact and, crucially, keeps the middle of the board free as a highway for moving other marbles around.

Keep transit squares open

Every move needs a clear path. The fastest way to lose is to wall yourself in so a marble you need can no longer reach its destination. Treat a few central squares as permanent transit lanes and resist the urge to park marbles there. If you ever can't find a path, the AI Smart Move hint on the game page will surface the best legal option — or tick Show moves to light up every square the picked marble can reach.

Pro habit: aim to keep at least half the board empty at all times. The moment you drop below that, switch from "build longer" to "clear now" until you have breathing room again.

Use bait and crossing combos

Two advanced tricks separate good players from great ones:

Bait moves: a marble of the wrong color can be parked to open a path, letting the same-color marble you actually want slide into the optimal slot next turn.
Crossings: arrange a shared square where a horizontal and a diagonal line both want the same final marble. Completing it clears both lines at once for a huge score from a single move.

The three mistakes that cap your score

Aimless moves: every move that doesn't build toward a line just feeds three more marbles onto the board.
Tunnel vision: fixating on one line means you miss the other colors quietly stacking up into trouble.
Cashing too early: clearing a five when you could have held for a seven leaves more than half your potential points on the table.

Internalize the free-turn rule, read the preview, and protect your lanes, and your scores will climb fast. When you're ready for the deeper picture, read how the board moves work under the hood in How the Pathfinder Works, or go straight for a record in How to Get a High Score.

Frequently Asked Questions

What is the fastest way to improve at Color Lines?
Stop clearing the moment you reach five. Because clearing a line is a free turn that drops no new marbles, every extra marble you add before completing it is pure profit — a seven scores 18 instead of 10, and a crossing combo can clear two lines from one move. Build four-in-a-row positions in several colors at once, watch the preview, and only cash a line when the board gets tight.

Why do edges and corners help?
A center marble can extend four ways, scattering your effort; edge marbles have fewer directions to manage and a corner anchors a line. Building along the rim keeps your lines compact and the middle clear for moving marbles.

When should I just clear a line of five?
Clear immediately when space is low or when the path to extend is about to be blocked by an incoming marble. Otherwise hold — patient players routinely turn fives into sevens and score several times more.

Can I see which squares a marble can reach?
Yes — tick Show moves under the board and every reachable square lights up with a dot when you pick a marble up. It's an optional aid, off by default, and it only visualises the clear paths the game already enforces — it never changes the rules.
