The 25:10 index market is a football sports spread betting type based on the result of one football match. The winning team is awarded 25 points, and the losing team receives no points. In the result of a draw, both teams are awarded 10 points each. If you back a team to win at 15-17 for £10 per point and the final score finishes 2-1 to your selected side, then you would make a profit of £80.
