Simple-to-play card game for two

WAR

When kids divide a deck and flip to see whose card wins, they’re likely playing this.

The clue describes a basic card game where two players split a deck and flip cards simultaneously—the higher card wins each round. "War" fits because it’s a straightforward, no-strategy game often played by kids, where the name humorously matches the competitive (but simple) nature of the game. The wordplay is direct, using "simple" and "two" to hint at the game’s minimal rules and player count. No hidden tricks—just a classic, easy-to-recognize answer.
