TU and TO in 1xbet cricket stand for Total Under and Total Over. Over/Under betting is known as a totals bet. The total in a cricket match is the total score made by a team in an innings. The oddsmakers set the total based on how they foresee the innings unfolding. For example, if the projected score for India in a T20I match is 160, the bookmaker may quote odds for a total under 160.5 and a total over 160.5.
