Can only get 577.

(10 - 2) * (2 * 4) = 64
9 * 64 = 576
576 + 1 = 577

If nobody can get that then go for this:

25 50 75 100 9 4

I'm out by 3. Can anyone else do this one? I can get 720.

I presume you did (6 + 3) x (7 + 1) x (7 + 3).

And I don't think it's possible to get any closer...

T = 187

(18 + 1) x 4 = 76
76 + 100 + 12 - 1 = 187

You can only use 1-10 as small numbers, and you can't do anything with 0 in the first place.

It does happen on very special occasions on Countdown that numbers other than 1-10, 25, 50, 75 and 100 come up.

On those occasions, however, Rachel doesn't let the contestants choose.

Can't get this myself but closest is

Impossible to get 734, I'd say...

Only five numbers there.

I can get 207: (75 - 6) x 3.

And 209: (75 - 50) x 8 + 6 + 3.

Is 208 possible? Don't think so, somehow...

Easy:

50 x 9 + 75 - 4.





How about:

25 100 50 75 10 10 ---> 136

premier10

100+75=175
175-50+10=135
???
Don't know if can get that extra 1

Apologies to everybody for the error. I understand how it would put people off but I can assure you that it is possible.

FWIW - I don't do random numbers. I write down some numbers, do some calculations in my head and come up with a target that way.

I can get 135 ((75+50+(10/10)) and 137 (100+50-10-(75/25)) but not 136.

My previous challenge in case anybody would like to have a go at it. Adding in an extra number but as I said it's doable with just the first 5 numbers.

I can't get 136 either

This took ages...but using original numbers and I can see Premier10 is in first with the very similar digits but anyway I'm so declaring it

6/3=2x75=150+50+8=208.


Now my mind needs a massage

Argh, never thought about doing 6/3!!

Well done.

136 is possible - you just have to think big.


In the meantime:

100 25 1 1 2 4 ---> 657

Aineoil

100 25 1 1 2 4 ---> 657

100+ 1 = 101

23 + 1 = 26

101 x 26 = 2626

2626 + 2 = 2628

2628 divided by 4 = 657

I take it you got the 16 from the 9 and the 7 - but how did you get the 60 from the 50, 6 and 5?


Anyway, try:

I think that I confused the system a bit with my edits.

I've answered BOP's and premier 10's ones in the above post and added the next puzzle at the bottom.

I think we are out of numbers so:

743

Go Harvey Go

75 x 10 - 8 - 5 + 6.

And an alternative solution to Clearlier's 221: 25 x 3 x 3 - 4.




Now try:

4 5 6 7 8 9 ---> 531
