Every word counts, so focus and think carefully about your choices.

In the brain-teasing co-operative game Sides, you have to weigh your options and wisely choose your words.

The objective of the game is simple: Each round, help two detectives find a mystery word. To do so, the other players (the witnesses) give detectives a one-word clue that starts with the letter at either end of the letter-card line.

The detectives then jointly offer an answer, and if they found the solution, two other players become the detectives and a new word is uncovered; if not, the witness players suggest a new clue with a new letter card. The fewer the clues used and the more words guessed, the higher the score. Will you beat the world record?
