Checkers, e.g.

DISCS

Think of the flat, round pieces used in many tabletop games that can be stacked or slid across a board.

Checkers, e.g." hints at the small, flat pieces used in the game—those round markers you slide across the board. The answer "DISCS" fits because checkers are often called discs, especially in contrast to other game pieces like dice or cards. It’s a straightforward example clue where the answer names the object itself.
