Connect each matching number pair with a continuous path and use every tile on the board exactly once.
Connect each matching number pair with a continuous path and use every tile on the board exactly once.
This version uses numbered endpoints on 6x6, 8x8, and 10x10 boards. Partial routes are allowed, and drawing through another unfinished route clears that route for a fast retry. The finish condition is strict full coverage: every pair must connect and every tile must belong to some path.
Arukone uses letters instead of numbers, but the core idea is almost the same: connect matching clues with non-crossing lines. If you have seen alphabet versions in books or apps, this game will feel familiar; the clue symbols are the biggest visual difference.
Some Numberlink books and apps only ask you to connect every pair, and unused empty spaces are allowed. This build is stricter than that. You do not finish just by making the matches; every tile must be claimed by a route.
Some rule sets discourage or forbid little fold-backs or U-turn-like detours because they can look wasteful. This implementation does not add a separate no-U-turn rule. If the final board connects every pair, avoids crossings, and fills the grid, the route shape is accepted.
Many mobile path games replace numbers with colored dots and focus on quick touch dragging. This build keeps that easy touch feel, but uses numbered pairs, a dedicated Hint button, Clear Selected Path, and export/load support.
Numberlink-style puzzles reach back to late-19th- and early-20th-century print puzzle culture, with Sam Loyd's 1897 newspaper form and Henry Ernest Dudeney's 1917 'A Puzzle for Motorists' often cited as early ancestors. In Japan, Nikoli later helped popularize the genre as Number Link and Arukone, making path-connecting logic puzzles a familiar part of modern pencil-puzzle culture. Coverage of Nikoli founder Maki Kaji in Reuters and AP also underlines how Nikoli helped simple, language-light puzzle ideas travel globally.
Yes. This implementation keeps partial routes on the board, and you can drag again from that pair later to extend or redraw it.
Not exactly. Some Numberlink variants only care about connecting pairs, while this build also requires full-board coverage. This version also uses numbers instead of letters, and it does not add a separate no-U-turn restriction.
Hint reveals one correct next tile on a solution path. It is meant to nudge your current layout rather than instantly solve the whole board.
Yes. The top menu includes export and load, so you can copy the current board into a code and reopen it later.
