Bored last satuday and wrote a simple random number generator for this game in php. If anyone wants the code (maybe they could build it into this thread I'd be delighted to give it)

Any suggestions for improvement welcome

Amendments made to number generation as per feedback

Your numbers are wrong.
The numbers are :
(you only list the 1-10 once)
[25] [50] [75] [100]

[1] [2] [3] [4] [5]
[6] [7] [8] [9] [10]
[1] [2] [3] [4] [5]
[6] [7] [8] [9] [10]

not to sure if you're allowed to use the square root when doing these

so first one
7 * 5 = 35 - 10 = 25 * 4 = 100 * 10 = 100 - 9 = 991

second one
75 - 4 = 71
8 - 3 = 5
71 * 5 = 355 - 3 = 352

Nope, I checked on the net and closest possible is 430.
I've already seen the solution for 430, so I'll let someone else solve it.

Hi All,

I'm new to this forum and am wondering what happens when nobody seems able to solve the previous puzzle. The current one from Square_igloo is unanswered since last night (and I can't answer it).

It's a great thread by the way.

Regards,

captainzapp

the closest i can get is 774...

7+8=15*(50+2)=780-6=774

if i give myself a brownie point for getting this close using only 5 of the numbers i could take that away and get 773?! ohterwise im at a loss!

if no one else can do this one i'll add some more numbers but correct me if I'm wrong.
