2-4-8 asks for one thing: connect dots carrying the same number. Draw a line through a run of matching values, horizontally or vertically, and they collapse into a single dot holding their combined total - so a chain of four twos becomes an eight rather than a four. That doubling rule is what separates it from an ordinary connect-the-dots game and what makes long chains disproportionately valuable. The board refills from below as you clear, which means the interesting decisions are about what you leave behind rather than what you take. Clearing a pair the moment you spot it keeps the board tidy but produces small numbers; holding out for a chain of five or six creates a value large enough to be worth building around, at the risk of the board filling with fragments in the meantime. It plays quickly, reads clearly, and is easy to pick up in a few seconds - though scoring well takes rather longer.
How to Play 2-4-8 : link identical numbers
Click or tap a dot and drag through neighbouring dots carrying the same number, moving up, down, left or right. Release to merge the chain into one dot holding the combined value. New dots drop in from above to fill the gaps, and longer chains produce larger numbers than several short ones.
Tips and Tricks
Count the chain before you release. Four matching dots merged together are worth considerably more than two separate pairs, and the difference compounds over a round.
Clear from the bottom of the board. Merging low down drops everything above into fresh alignments and often reveals a chain you could not see.
Keep your largest value in a corner and build towards it rather than beside it. A big number stranded in the middle blocks chains in four directions.
When the board fills with mismatched small values, take a short chain to force a refill rather than waiting for a long one that may never appear.
Frequently Asked Questions
How does the merging actually work?
A chain of matching dots combines into their total rather than simply doubling once, so connecting four twos gives you an eight. Longer chains are worth much more than repeated short ones.
Can I connect diagonally?
No. Chains run horizontally and vertically only, which is what makes board position matter as much as spotting the matches.
Is there a time limit?
No. The board waits, so you can study it before drawing a chain and there is no penalty for taking your time.
What ends a round?
Running out of valid connections once the board is full and no neighbouring dots share a value.
Do I need to install it?
No. 2-4-8 runs in the browser on GN Math and works by dragging with a mouse or a finger.
