This is the reason that we need to work with big numbers.

Please check this my Friend: http://pastebin.com/fhF3i6y0
If you see, when you increase the number then the result will be 0 on every 26 time. This mean: 1:26 for get the result: 0 !

I have now whats wrong! When the Difficulty changes under 1 million then the success rate is absolute high.
Example when you want play with 1.1 ether and you get 118181817 Diffi, then you have 1 : 59 090 908 rate. This means the calculation is wrong.
I disable the contract until i can fix this problem.

Very thankful for your report!

I will reply when i'm done with the contract.

no it's false. You assume you can divide both sides of the modulo and preserve the chances, it does not work like that.

the bignumber*1million should be a multiple of 118'181'817 for your contract to trigger the transaction.
that's 1 chance over 118'181'817

it's not the same as bigNumber divisable by 118 which is a chance over 118.

Btw you should know that there are no float (real) numbers in solidity so your 118.18 makes no sense.
