Even after 14 minutes of play, Kalmar was able to score the first goal of the match.
Oliver Berg got the chance from the penalty spot and was cool when he scored his eleventh goal of the season.
17 minutes later, the home team would then expand.
Romario, served by Filip Sachpekidis, managed his position well and scored 2-0.
But Varberg replied after a minute.
Alexander Johansson performed admirably for Anton Liljenbäck.
With the minute left of the first half, Ryan Moon then offered an artistic goal when he bounced down a header from the 1-0 shooter Liljenbäck and on a volley thundered in 2-2 behind Lucas Hägg-Johansson.
A goal that determined the end result
The result means that Varberg picks up a valuable point in the Allsvenskan bottom battle.
