Bonus iCoins are instant rewards Club iWin members get at the time of redemption. In the Club iWin subscription description, it is the 10% rewards on purchases.
In the example below, there is the monthly charge for Club iWin and 1000 iCoins have been added leaving the new balance of 81,900. Then a purchase for the game Jewel Quest 2 is made. First the 100 bonus iCoins are added, leaving the total at 82,000 iCoins. Then the 1000 iCoins for the cost of the game is removed, leaving the total at 81,000 iCoins.
It should be noted that your "transaction history" activity tab can be a little confusing in this regard. Because your bonus iCoins are occurring simultaneously with your purchase, the ordering sequence can be a little off kilter.
