Hi-Lo Overview
Hi-Lo is a Card guessing game with progressive multiplier stacking with 97.0% RTP and medium volatility. The maximum multiplier is 100,000x, making it a balanced game that offers consistent returns with occasional larger wins. Every outcome is provably fair — verified through HMAC-SHA256 cryptography.
Top Strategy Tips
1. Always guess based on the probability display — pick the more likely direction.
2. Cash out when you've stacked 3–5 correct guesses for reliable profits.
3. Cards near the middle (7, 8) are the hardest to predict — consider cashing out before them.
4. Cards at the extremes (Ace, King) are nearly guaranteed guesses — capitalize on these.
5. The multiplier compounds, so a streak of 8+ correct guesses can reach 50x–100x territory.
Understanding the Odds
With 13 card ranks, if the current card is rank R (1=Ace to 13=King): probability of Higher = (13-R)/12, probability of Lower = (R-1)/12 (excluding the same rank). When the card is a 7 (middle): Higher and Lower both have ~50% chance. At Ace: Higher is ~92% likely.
Bankroll Management
With a 3.0% house edge, Hi-Lo will cost you about 3.0 coins per 100 wagered over the long run. To survive variance: never bet more than 2% of your total bankroll on a single guess. If your bankroll is 1,000 coins, keep bets at 20 or below. Set a stop-loss at 30% of your session bankroll and a win target at +50%. When you hit either limit, stop and reassess.
House Edge Explained
Hi-Lo has a 3.0% house edge (97.0% RTP). The multiplier for each guess is 0.97 / probability_of_correct_guess. When you're almost certain to be right (e.g., guessing Higher on an Ace), the multiplier is tiny (~1.05x). When it's a close call, the multiplier is larger (~1.94x).
Provably Fair Verification
Every next card in Hi-Lo is cryptographically predetermined before you guess. The entire sequence of cards is predetermined using HMAC-SHA256(server_seed, client_seed:nonce). Each card in the sequence consumes one float from the hash chain, mapped to a rank (1–13). The full sequence exists before your first guess. Visit the Fairness page to verify any past result.
