Over/Under (O/U) betting in football refers to betting on the total number of goals scored by both teams within 90 minutes of regular play (excluding extra time). The bookmaker sets a predetermined number, and bettors must predict whether the total goals will be Over (Tài) or Under (Xỉu) this number.

Let’s explore the details of Over/Under betting with win betting tips below!

What is Over/Under Betting? How to Read the Odds

Over/Under betting is also known as Goal Line Betting, Totals Betting, or O/U Betting. In bookmaker odds tables, it is denoted as O/U, short for "Over/Under."

If you believe the total goals will be higher than the bookmaker’s number → Bet on Over (Tài, O).

If you believe the total goals will be lower than the bookmaker’s number → Bet on Under (Xỉu, U).

If the total goals exactly match the bookmaker online number, the bet is refunded (Push).

The same principle applies to Over/Under bets on penalties, corner kicks, and other game events. However, for the best results, consider the betting strategies we discuss below.

If total goals equal 3 (e.g., 2-1, 3-0) → Win half the bet (200k × 0.71 ÷ 2 = 71k).

If total goals are less than 3 (e.g., 1-1, 0-0) → Lose full stake.

Betting on Under (Xỉu) – 200k stake

If total goals exceed 3 → Lose full stake.

If total goals equal 3 → Lose half the stake.

If total goals are less than 3 (e.g., 0-0, 1-1) → Win full bet (200k × 1.23 = 246k).

Betting on Over (Tài) – 200k stake

Effective Strategies for Over/Under Betting

To improve your accuracy in Over/Under betting, consider these expert strategies:

1. Analyze Team Playstyles

A team’s style of play greatly affects the likelihood of an Over or Under outcome:

If both teams play aggressively, the match is likely to have many goals, making an Over bet more favorable.

If both teams focus on defense, the match may have fewer goals, increasing the chances of an Under bet.

2. Evaluate Match Conditions

Beyond playstyles, analyze additional match details, including:

Starting lineups

Current form and recent performances

Head-to-head history

Home vs. Away advantage

These factors help gauge each team’s strength and make more informed bets.

3. Follow Expert Betting Insights

If the first half ends 0-0, avoid rushing into an Under bet.

Teams often switch to an attacking strategy in the second half, increasing the chance of goals.

For high-profile matches (e.g., MU, Barcelona, Real Madrid), Over bets are often safer.

These teams have strong offensive capabilities and higher goal-scoring potential.

For leagues with a defensive style (e.g., Portuguese Liga, Ligue 1, Brazil), Under bets are often safer.

Matches in these leagues tend to have fewer goals due to cautious gameplay.

Observe the first 10 minutes before placing an Over/Under bet.

Early match dynamics often indicate how the game will unfold.
