Number Fill-In

A grid of empty runs and a list of numbers. Every number has exactly one home.

How to play

Fit every number from the lists into the grid — each number is used exactly once.
The lists are grouped by how many digits each number has; count a run of white squares to see which numbers can fit there.
A couple of numbers are already filled in to get you started.
Where numbers cross, the shared square must use the same digit, so use the digits you already have to narrow things down.

None of these give anything away — they are just how people who do these all the time get unstuck.

Count the white squares in a run, then look only at the numbers with that many digits.
Start with the digit-length that has the fewest numbers in it - a length with only one number is a free placement.
Where an across and a down number cross, the shared square must match. Use the digits you already have to narrow things down.
Cross each number off the list as you place it, so you never place one twice.
If a run will not take any remaining number, something earlier is wrong - back up rather than forcing it.

Have a go at this one first — it is smaller than the real thing. The answer key is hidden until you ask for it.

3 DIGITS: 341, 398, 832, 855, 856
