Under 3.5 meaning in betting

Under 3.5 goals is a bet on there being less than four goals scored in the match. So if you placed a bet on under 3.5 goals and there were zéro, one, two or three goals scored, you would win. If four or more goals were scored, then your bet would lose.

This type of bet is trendy in soccer betting, where matches can often be low-scoring.
