How to Analyse Over / Under (Tài Xỉu) Simply

Over/Under betting in football (also called Tài Xỉu in Vietnamese) is a very popular market. Instead of picking which team wins or loses, you predict whether the total goals scored by both teams will be over or under a football prediction for today given line (for example 2.5, 3.5 goals, etc.). Because the method is straightforward, many bettors like it as it depends more on match dynamics than team reputation. Here’s a simple, step-by-step guide to analysing Over/Under bets well.

1. Understand the Line

Before anything, you must understand the line you are betting on. A "2.5 goals" line means:

• Over 2.5 = you need 3 or more total goals in the match to win

• Under 2.5 = you need 2 or fewer goals to win

Other common lines also include 1.5, 3.5, 4.5 etc. The half-goal ensures there is no draw or push (no refund) on that bet. Knowing this clearly prevents surprises.

2. Check Recent Goal Trends

A very effective first filter is to which is the most accurate free football prediction site look at how many goals the two teams are scoring and conceding recently:

• Last 5–10 games: total goals per game for each team (both scored + conceded)

• How many of those games ended with high goals (≥ over line), how many with low goals (≤ under line)

If both teams have a pattern of getting 3+ goals when they play, then Over is more likely. If both are defensive and score few, then Under may be safer.
