The basic rules of 21 involve adding the value of an initial two card hand in hopes of being dealt a value of twenty-one. If a value of less than twenty-one is dealt, the player may choose to be dealt single cards until they either reach a value of twenty one, reach a value they feel comfortable to play, or reach a value that exceeds twenty-one. The winner holds a hand with a value of, or nearest to, twenty-one without exceeding it.
