Anyone good at solving Calcudoku?

I somehow need to get a password number from this 5x5 calcudoku grid which runs from top left to bottom right. I've no idea where to begin :(

I'm no expert at these, but will take a crack. There may be an easier method...

Labelling as per a chess board (A1=BL. E1=BR)

'30x' can only be 1/2/3/5 (sum=11).
Rightmost 2 columns sum to 30, so D1 =3 -> C1=5. (remember for later that '16+' is 1/2/4/4/5)

Noting '12x' in row 2 can only be 3/4. Look at '2-' in col C. It's either 4/2 or 1/3.
If it's 4/2, C2=3 -> B2=4, and C5=1 (to complete col C) -> B5=4.
There can't be 2 4s in col B, so the '2-' in col C is 1/3.
So C2=4 & B2=3. Also C5=2 & B5=5.

The 2/5 in '30x' are in D4/E4, so E5=3 & D5=1

The top row, then Col A, then col C can be completed easily now.
The required 4s can only go one way in the '16+' box, and the puzzle can be completed easily from there.

Not too tricky. Sometimes you need to just examine the options available in the most restrictive area of a puzzle. If you are struggling with what I've presumed to be easy steps, PM me.
