Hi-Lo is an extremely basic guessing card game. Guessing games are a popular mainstay in casinos, due to their relatively even odds. These games often are played for extremely high stakes, as there is close to a 50/50 chance of winning and losing.

So the probability of correctly guessing both the suit and rank of the next card in a game of Hi-Lo, assuming that the previous card has already been revealed, is 1/204 or approximately 0.49%. Two cards are drawn at random from a deck of cards with replacement.
