Don't you need at least one large?

no, on the original game you can choose all small numbers.

I don't think you have to have any large ones - I think you're allowed to say "6 from the bottom please Carol" or even "6 from the top please Carol" - at least you used to be. It was a good way of snookering your opponent if you were ahead before the numbers - though not very sporting.

Anyway,

there's only 4 from the top, but yeah, you can choose all 4 of them along with 2 small ones.

Yeah, I'm pretty sure this can't be done either. (Was my own one, but I didn't check for a solution in advance.) Have tried everything. This was featured on Countdown once, wasn't solved (in the 30 seconds, or by Carol) then either.

Happens quite a lot, numbers which can't produce a solution.

By the way, all small numbers or four big, two small can, and has, happened on the show, so a selection like 1, 2, 3, 4, 5, 6 and a target of several hundred.

You're joking right?

75 * (10+1) = 825 + 50 = 875 + 100/25 = 879

I won't start another one cos I've one unfinished as does derek27

Oh, I'd forgotten that -

6, 3, 1, 9, 25, 75
target = 193

75*3 = 225
225-25=200
200-(6+1)=193

I think there are a couple of unsolved ones on the board, so I won't muddle things up by posting another one.

Just to give the alternative on this one. 626 is possible on the other side, but not the elusive 625.

(((1+6)*8)*(1+10))+10 = 626

A very tough one. Can it be done, do you know, Meditraitor?

I can do 720 a couple of ways, e.g.

2/2 = 1
6+4=10
10-1 = 9
8*10 = 80
9*80 =720
