logical would be that if a pool has 33% of hashpower, return should be 3x of amount
You got the wrong idea about this game because this game isnt something sort of that kind. Basically this game is about a collective pot that the amount will be divided to all the winners proportionally according to their wager amount
i.e The winning pot has an amount of 1
BTC and Eligius is the pool that mined the xxx777 blocks
There are 3 addresses that bet on eligius to mined the block with the wager amount as the following
Address A : 0.01
BTC >> 50 %
Address B : 0.005
BTC >> 25 %
Address C : 0.005
BTC >> 25 %
House takes 1% fee so 1
BTC x 1 % = 0.01
BTC and thats leave the pot with 0.99
BTC amount
0.99
BTC will be divided among the 3 addresses proportionally according to their wager so
Address A will receive 50 % x 0.99
BTC = 0.495
BTCAddress B will receive 25 % x 0.99
BTC = 0.2475
BTCAddress C will receive 25 % x 0.99
BTC = 0.2475
