Hi-Lo (also written HiLo or Higher-Lower) is a card-prediction game where a player sees a face-up card and bets whether the next card will be higher or lower. A correct prediction grows the multiplier — the player continues predicting (accumulating the multiplier) or cashes out. An incorrect prediction loses the stake. Hi-Lo is one of the few provably fair crypto casino games with a skill element: the optimal decision (higher or lower) depends on the value of the current card. For mid-range cards (7 or 8 on a 13-card deck), the choice is approximately 50/50 — and most implementations allow a "skip" to request a new card without betting. For extreme cards (2 or Ace), the optimal decision is clear and the probability is high.
This guide covers how Hi-Lo works, the house edge, optimal card-by-card decisions, skip strategy, and cash-out timing. For the dice guide (similar 1–2% HE, no skill element), see dice guide.

How Hi-Lo Works — Card Deck, Predictions & Multiplier
Deck setup: Most crypto casino Hi-Lo uses a 52-card deck (no Joker). Cards rank Ace (low = 1) through King (high = 13). Some implementations use Ace as both low and high (14). The deck may be infinite (continuous re-deal from full deck each card) or depleting (single shuffled deck without replacement). Infinite deck is most common at crypto casinos — each card is independent of previous cards.
Round mechanics: (1) Player places an initial bet. (2) First card is revealed (face-up). (3) Player predicts: Higher, Lower, or Same (some implementations). (4) Next card revealed. (5) Correct: multiplier applied, player may continue to next card or cash out. Incorrect: round ends, stake lost. Same: some implementations treat as a loss; others push (return stake). (6) Player continues predicting and accumulating multipliers, or cashes out at any point to collect multiplier × original stake.
House edge: Hi-Lo house edge: typically 1–3% depending on implementation. BC.Game Hi-Lo: ~1%. Stake Hi-Lo: ~1%. The house edge is built into the multiplier values — payouts are slightly below actuarially fair. For a card with 12 higher outcomes out of 51 remaining cards (7 shown, predict higher): fair multiplier = 51/12 = 4.25×. At 1% HE: actual multiplier ≈ 4.21×.
Skip function: Most crypto casino Hi-Lo implementations allow the player to "skip" a card — request a new card from the deck without betting on the current card's direction. This is critical for mid-range cards (7, 8) where neither higher nor lower offers a meaningful probability advantage. Always use skip on cards where your probability of winning either direction is below ~55%.
Provably fair: BC.Game and Stake Hi-Lo are provably fair. Card sequence is determined by server seed + client seed + nonce (HMAC-SHA-256). Before the round: server commits a hash of the server seed. After the round: reveals the seed. Player verifies the card sequence was predetermined. This prevents the operator from changing the card after seeing the player's prediction.
Optimal Hi-Lo Card-by-Card Decisions
Decision rule (infinite deck, Ace = low = 1, King = high = 13): Current card is Ace (1): Always predict Higher (12/13 cards are higher = 92.3%). Current card is 2: Predict Higher (11/13 = 84.6%). Current card is 3: Predict Higher (10/13 = 76.9%). Current card is 4: Predict Higher (9/13 = 69.2%). Current card is 5: Predict Higher (8/13 = 61.5%). Current card is 6: Predict Higher (7/13 = 53.8%). Current card is 7: Edge is minimal (6/13 = 46.2% higher, 6/13 = 46.2% lower, 1/13 = 7.7% same) — SKIP if allowed. Current card is 8: SKIP. Current card is 9: Predict Lower (8/13 = 61.5%). Current card is 10: Predict Lower (9/13 = 69.2%). Current card is Jack: Predict Lower (10/13 = 76.9%). Current card is Queen: Predict Lower (11/13 = 84.6%). Current card is King: Always predict Lower (12/13 = 92.3%).
Skip strategy: When the current card falls in the middle range (typically 6–8 on a 13-card scale) where neither higher nor lower offers a significant probability advantage, use the skip function to reveal a new starting card. Skipping does not cost a bet — you only bet when you have a directional edge. This is the key skill element in Hi-Lo that doesn't exist in dice or crash.
Cash-out timing: Like crash and Mines, multipliers compound quickly after several successful predictions. Decide in advance how many correct predictions to target before cashing out (e.g., always cash out after 5 correct predictions, regardless of the multiplier). Five consecutive correct predictions on 70% probability cards: (0.70)^5 ≈ 16.8% probability. Multiplier after 5 correct 70% predictions: approximately 5.0×. EV of this sequence: 0.168 × 4.0 (net profit) − 0.832 × 1.0 (loss) ≈ −13% — wait, this doesn't account for partial sequences. The house edge is embedded in the multiplier calculation, not in a winner-take-all result — your EV at each step is −house_edge%.
Hi-Lo at Crypto Casinos — Availability and Variants
In-house provably fair Hi-Lo: BC.Game Hi-Lo and Stake HiLo are the primary in-house provably fair Hi-Lo games. Both use standard 52-card decks, offer skip functionality, and provide full provably fair seed verification. Both operate at approximately 1% house edge.
Live dealer Hi-Lo: Some Evolution Gaming live casinos offer card prediction game variants similar to Hi-Lo — notably Top Card in some regions, or Hi-Lo elements within Crazy Time bonus rounds. These are distinct from pure in-house Hi-Lo and carry different house edges (typically 2–5% for live dealer variants).
Provider Hi-Lo variants: Hacksaw Gaming, Play'n GO, and other game studios offer Hi-Lo-style games with different deck configurations, multipliers, and paytables. RNG Hi-Lo games from licensed providers: typically 95–97% RTP (3–5% house edge) — worse than provably fair in-house Hi-Lo (1% HE).
Stake limits: In-house Hi-Lo minimum: typically $0.01. No hard maximum — BC.Game and Stake accommodate large Hi-Lo bets. For very high single-round stakes, contact your VIP account manager to confirm limits before starting a session. See VIP account manager guide.

Frequently Asked Questions
What is the house edge in crypto casino Hi-Lo?
1–3% depending on implementation. BC.Game Hi-Lo and Stake Hi-Lo both operate at approximately 1% house edge — among the lowest available at crypto casinos alongside crash, dice, and Mines. RNG Hi-Lo games from licensed providers (Hacksaw Gaming, Play'n GO) typically have 3–5% house edge. Always prefer provably fair in-house Hi-Lo (1% HE) over licensed RNG variants.
What is the optimal strategy for Hi-Lo?
Use the card value to determine direction: Ace (1) → always Higher (92.3%). High cards (Q, K) → always Lower (84.6%/92.3%). Mid-range cards (7–8 on 13-card scale) → always Skip (neither direction offers meaningful advantage). Never bet on a card in the 45–55% probability range — skip it. The skip function is Hi-Lo's key skill element vs pure chance games like dice and crash.
Is Hi-Lo provably fair at Bitcoin casinos?
Yes — BC.Game Hi-Lo and Stake HiLo are provably fair. Card sequence is predetermined by HMAC-SHA-256 using server seed + client seed + nonce. Before the round: server commits a hash of the server seed. After the round: seed revealed, player verifies the card sequence was fixed before any predictions. This prevents the casino from adapting the card to contradict your prediction after it's made.
