Number Sequence 1-to-25 Puzzle

Number Sequence is a number puzzle game known as many different names, such as 1-to-25, Route Number or Number Path. It's a hard logic game for those who like brain challenges.

You start with an empty board and have 25 numbers to place in 25 squares. But you have to follow 2 rules to put each number on the board:
• The number you're placing (eg "7") must be adjacent to the previous one ("6")
• And it must be placed on a certain highlighted row or column

To solve, use the pencil tool to sketch the possible positions for each number, then as you advance to the next numbers you will see which of the previously sketched numbers are still valid. This way you can go back to those numbers and remove the ones that are not valid anymore, for example if they dont connect with the sketches of the next number.

After you narrow down to only 1 possible location for that number, place it permanently using the pen tool. Follow this logic and you can solve boards of any size!

Easy boards are small (4x4), have up to 16 numbers, and can easily be solved in under a minute.
Harder borders are much bigger, with 64 or more numbers to place, and could take hours to solve! For these boards you must use the pencil tool or else you will have to guess and will get stuck.

Number Sequence is a number puzzle game from the makers of the puzzle hits Einstein's Riddle Logic Puzzle and Real Jigsaw.
