It was released in 300 theatres worldwide.[15] The film gained average reviews from critics, with a reviewer from Rediff stating "Chikku Bukku could have been a neat romantic tale, but the journey breaks down too much to ever hold your attention for long", concluding it as "tedious".[16] Behindwoods offered a similar review, though stated "On the dot, if there is one perfect reason to get you intact with the show, the brilliant visuals stand out as a substantial ingredient."[17]The Hindu stated "Chikku Bukku is a neat film that moves on parallel tracks, before the lines meet and culminate in a joyous climax. And though guessable, the narration sustains your interest. A feel-good romance!"[18]
