I will be nice, if you see pics thrice. I bear fruit of trees, sometimes in 3's. I am but an arm's length in front of you. What am I?

Why this works

This riddle plays with multiple meanings and associations. The phrase "I will be nice, if you see pics thrice" refers to the three reels of a slot machine that you need to line up to win, as "pics" hints at the images or symbols shown on those reels. The line "I bear fruit of trees, sometimes in 3's" relates to the classic fruit symbols (like cherries, lemons, and oranges) commonly found on slot machines, which often appear in groups. Finally, the phrase "I am but an arm's length in front of you" suggests that slot machines are typically located close to where players stand, making them easily accessible and inviting. Together, these clues cleverly lead to the answer: a slot machine!
