During the final round of most televised tournaments SportingIndex offer live prices as the action unfolds.
Therefore you have the opportunity to outwit their market makers as each shot is hit. The scoring system awards points as follows: 1st = 25 points, 2nd = 10, 3rd = 5, all others = 0.
Here's an example. In the British Open SportingIndex might offer predictions for eight players in contention during the last round live on TV. Walking off the 15th green, after a birdie to bring him within two shots of the leader, SportingIndex might price Vijay Singh at 7-9 points. If on the 16th hole his drive went into the water and the prospect of him dropping a shot looked highly likely, SportingIndex might revise their quote downwards on him to 3 - 6. Having followed the action closely on TV, you might believe that the situation isn't as bad for Singh as it appears, and in fact Vijay may well be able to rescue a par at the 16th. As a result you might decide to place your bet high at 6, for the stake of your choice, in this case say £10 a point.
If Singh did drop a shot at the 16th but managed to keep his composure and finish second in the tournament, he would have been awarded 10 points in their Live Index. As a result you would have made 4 times your stake, in this case £10 per point: (10 - 6) x your stake = 4 x £10 = £40.
However, having seen him find the water, you might have decided that he had little chance of finishing in the top two, and decided to place your bet low at 3. In this scenario, your judgment would have been incorrect and you would have lost 7 times your stake as Singh was awarded 10 points for finishing second: (3 -10) x your stake = -7 x £10 = -£70.
