Calculation formula:

Money received = Bet amount × European rate

For example: If you bet 100,000 VND on a football team with odds of 2.50.

100,000 × 2.50 = 250,000 VND (including capital and interest).

European odds are easy to understand, but they do not clearly show how much money a player loses if they bet wrongly.

• If the team you choose -0.5 This means that the team must win for you to receive money.
• If you bet on the team +0.5, as long as that team draws or wins, you will win the bet.

This rate is more attractive because it reduces the risk of a tie and creates more betting options.

• Draw: 3.20
