\rThe constructor and the 1xBet bet builder are exceptionally different things. The builder is essentially a type of accumulator bet which allows you to combine multiple types of betting. For example, when you bet on Liverpool vs Manchester United, you can play the straight wager, combine it with an over-under, and even bet that Takumi Minamino will score a goal.On the other hand, the bet constructor allows you to wager on fantasy teams that you’ve made yourself. Additionally, you can only make straight wagers.\r\r
