How to play Marble Lines
Marble move in straight lines only
A marble slides along its own row or its own column. It cannot travel diagonally, and every square between it and the destination has to be empty — it will not push past another marble or land on top of one.
Five in a row clears
After a move, any unbroken line of five or more marbles of the same colour — across, down, or either diagonal — is removed. The line runs through the square you moved into, so a move can complete two lines at once, and both are cleared.
Six or more clears the whole run
A line longer than five is removed in full, not trimmed back to five. The whole unbroken run of one colour goes.
A move that clears nothing costs you three marbles
If your move does not complete a line, three new marbles appear on empty squares. They are placed so as not to complete a line by themselves, so you are never handed a free clear you did not earn.
New marbles never land on top of existing ones
They only ever go into empty squares, so nothing already on the board is replaced or lost.
The round ends when the board fills
With no empty square left there is nowhere to slide to, and the round is over. The number of marbles you cleared is your result.
Marble Lines Tips and Strategy
Never shuffle without a line
A move that clears nothing puts three more marbles on the board, so rearranging to look for a better position is the most expensive habit here. Look for a line first, and make the move that completes one. The new marbles never form a line by themselves, so the board stays fair, but the empty squares are what run out.
Move the marble that finishes
The slide has to be the one that puts a marble at the end of the run, not one that shifts something already placed. Look along every row and column for a colour one square short of five, and check whether the square it needs is clear. Moving a marble with no part in the clear is why boards stall.
Extend a line, not start one
A run of six or more clears in full, so a single marble added onto an existing line of five is much better than two separate lines of five. When you have a choice, lengthen something you already have rather than beginning a new run in a corner. Starting fresh leaves fours scattered around that still need marbles.
Marble Lines — Frequently Asked Questions
Why will my marble not move there?
Either the destination is not in the same row or column, or another marble is standing in the way. Check the line between them.
Why are there suddenly more marbles?
Your last move did not clear anything, which adds three. Making a line instead of shuffling is the way to keep the board from filling up.
Does a line of six count as two lines of five?
No. It is one run of six, and all six marbles in it are cleared.
Does it need installing or an account?
No. It runs in the browser on a phone, tablet or computer and works offline after the first visit.
