At this time of year fun can be hard to find; cold dark mornings, feeling flat after Christmas and a long time until the next pay check.
And it is quite hard to find all the fun in the grid below. Starting at any F and moving horizontally or vertically to an adjacent U, and then horizontally or vertically to an adjacent N, how many ways can you make the word FUN?
| N | U | F | U | N |
| U | N | U | N | U |
| F | U | F | U | F |
| U | N | U | N | U |
| N | U | F | U | N |
From each of the four Fs on the edges there are three Us that can be used, and for each of those three Us there are two Ns that can be used. This makes six FUNs for each of the four Fs on the edges, and 24 in total.
From the F in the middle there are four Us that can be used, and for each of those four Us there are two Ns that can be used. This makes eight FUNs for the middle F.
So there are 32 FUNs to be found in the grid.
