A Gambling Project

[quone17]

one problem is the people who start might have to wait a long time until the 100 people enter and they'll begin to doubt if the raffle will ever occur.  maybe set a time limit and/or person limit so that they know it will start on a certain date even if only 50 people show up (and then win only .5 btc)

Nice point, but there is one problem in implementing it in this system, because our winner is dependent on blockchain.info tx_index. We are adding up Tx indices to get a number between 0-99. But, if I stop the game depending on the participation, then how will I decide the winner ?

Suppose there are 34 transactions. If the rightmost 2 digits of the added result is 73, then no one will win it and this is bad. Can u please suggest any counter mechanism to sort out his problem ?

Take the sum of tx_indexes modulo number of entries. This gives a number between 0 and (number of entries - 1). If you either add 1 to the result or number your entries starting from 0 you have found the winning entry that would get the jackpot minus house edge.
100 entries is just a special case of this - modulo 100 just means to take the last 2 digits.
Of course, it requires some arithmetics to check whether the right transaction won - just taking the last 2 digits is easier. But then adding up 100 tx indexes is already quite some bit of work, so few people would check manually.
Another possible problem (unless I misunderstood the function of tx_index) is the placement of transactions in the list - are they sorted strictly by tx_index, or by arrival at your node?

(note that even though I gave technical advice on how such a thing might be done, I generally recommend against gambling, especially if you don't really have money that you won't miss when you lost it...)

Thank u for the solution ..so what I understand, if we have a tx_index sum of 987654321 and 89 transactions at the end of the time limit, then 50 is the winning transaction. Because => https://www.google.com/search?q=987654321%2589 ...I'm NOT sure how people are going to accept it. I'm waiting for community feedback for this rule.

Regarding the sequence of transaction, it is by the arrival at my node. I mentioned it at Point 3 of http://www.100bit.co.in/rules.php

@Onkel Paul Yes, I agree that if 0.01 BTC is something that someone cant afford to lose, he/she should stay away from this game. At the same time, I urge you to make the first transaction for a kick start

I have no problem with that rule at all.
Good luck to your project
