Greetings,
This game is a lot of fun and pays out well.
Yes it is a Isk doubling game, and it works like this.

1. send any ammount of isk you want doubled. 5 to 100 mill.
2. in the area for info in transfer put your number.
3. claim winnings or not... let me explain.

This game is really more of a pick a number with a hand grenade then anything else.

(example) number is 25 (example) you guess 87. No win, you guess 64 you win you isk back. you guess 30 you win 2x you deposit


so its simple really. if you are over 50 numbers away you win nothing.
25 number a lower you win your isk back.
within 5 numbers either way 2x win.

one try per each deposit
