The second season saw the addition of bonus letters to Bonus Lingo (known as free letters in Season 2). These allowed the team to fill in one of the spaces in a Bonus Lingo word and could be called for at any time, even if filling a space would result in the word being revealed (the team still had to say and spell the word to receive credit for it). The team received one bonus letter for winning the match plus one more for each Lingo they made.
