One card revealed. Guess if the next is higher or lower. Stack guesses to compound your multiplier — but cash out before you bust. House edge ~4%.
| Card is 7 | Higher: 13 cards above 7 / 13 = ~2.13× · Lower: ~2.13× |
| Card is A (lowest) | Higher: ~1.07× · Lower: impossible (game forces you up) |
| Card is K (highest) | Higher: impossible · Lower: ~1.07× |
| Card is 2 | Higher: ~1.13× · Lower: 12.48× (only A wins) |
| The ~4% house edge is built into each guess. Stacking 5 guesses multiplies multipliers but the edge compounds too — after 10 perfect guesses, your true expected value is 0.96^10 = 66% of the stated multiplier. Cash out early. | |
Hi-Lo (or "Higher/Lower") is a simple guessing game: a card is shown, you predict whether the next card will be higher or lower in rank. Payouts adjust based on the probability of your call — guessing higher than a 7 pays more than guessing higher than a 3 because it's less likely. House edge of about 2% under normal paytables.
A card is shown. You bet on whether the next card will be higher or lower in rank (Aces are usually high). If you guess correctly, you win at the payout shown on the screen, which depends on the current card. Many Hi-Lo variants are "streak" games — you can choose to keep playing (using your winnings as the next bet) or cash out after each round; one wrong call wipes the streak.
On a streak version, the EV decision is: cash out when your cumulative multiplier exceeds the expected value of continuing. For most paytables this is around 2-3x your starting bet. Greed punishes — a five-correct streak from 7-high might pay 20x but the probability of getting there is around 1 in 50. On single-round versions, just pick whichever side has the higher payout times its hit probability; for a true 50/50 card (an 8 in a deck with no other 8s removed), both sides have the same EV. Tied next cards usually count as losses, which is where most of the house edge originates.
For a 52-card deck with the current card showing 7: there are 28 lower cards (A-6, four each, 24 + 4 = some recount needed). Actually: A,2,3,4,5,6 = 24 cards lower; 8,9,10,J,Q,K = 24 cards higher; 7s remaining = 3. The Hi-Lo bet on "higher" wins 24/51, the Lo bet wins 24/51, ties hit 3/51. Payouts are typically 1.96x on either side (with tied-card-loses), implying expected return 0.96 × 24/51 = 0.451, plus zero on ties or losses, giving ~9% house edge if naively bet — but better paytables and "tie returns half" rules drop this toward the 2% commonly advertised.
Hi-Lo descends from "Polish Poker" and various street card games. It first appeared in casinos as a TV-style game show concept in the 1970s and migrated to online casinos in the 2000s as one of the simpler "instant" games.

| Lower (current card is K) | ~1.08x | 12/13 chance |
| Higher (current card is K) | ~13x | Only Aces beat — rare |
