Rules, Strategy & Odds
HiLo is a game of foresight and luck, challenging players to guess whether the next card will be higher or lower. Make consecutive correct guesses to increase your winnings, and decide when to cash out for maximum rewards.
The core mechanics of HiLo broken down step by step.
The game shows you a card from a standard deck (Ace low to King high).
Guess whether the next card will be higher or lower than the current one.
Each correct prediction multiplies your stake. The multiplier depends on the probability of your guess.
Lock in your winnings at any time, or keep guessing to build a larger payout.
Connect a Solana wallet (Phantom, Solflare, or Backpack) to Zexo.
No account needed — your wallet is your identity. Zexo never takes custody of your funds.
Select which token you want to play with: SOL, USDC, ZEXO, JUP, BONK.
Each token has its own liquidity pool. Payouts are in the same token you bet with.
Enter your wager amount and configure any game-specific settings.
All game parameters (odds, multipliers, house edge) are transparently displayed before you confirm.
Confirm the transaction in your wallet and play. Results settle instantly on Solana.
Every outcome is provably fair and verifiable on the Solana blockchain.
HiLo is one of the few games on Zexo where your decisions meaningfully affect the outcome. While each card draw is random, you control two things: your Higher/Lower prediction and when to cash out. The multiplier system is designed so that "obvious" predictions (calling Higher on a 2) pay less because the probability of being right is high, while "risky" predictions (calling Higher on a King) pay much more. This creates a fascinating dynamic where you're constantly weighing guaranteed small gains against potential big multipliers. The cashout mechanic adds another layer — even if you're on a hot streak, the probability of eventually hitting a wrong guess approaches 100% the longer you play, making timely exits essential.
The most common mistake is not cashing out when you're ahead. After 4-5 correct guesses, the temptation to push for "just one more" is strong, but mathematically the chance of eventually losing grows with each round. Another mistake is taking the risky side on middle cards (6, 7, 8) for the higher multiplier — the probability difference between Higher and Lower on a 7 is almost 50/50, making the "risky" call barely more rewarding.
Set a cashout target before each round. For example, decide you'll always cash out after 4 correct guesses or at a 3x multiplier, whichever comes first. This prevents emotional decision-making and gives you a consistent, repeatable strategy.
HiLo on Zexo is provably fair — every outcome is verifiable on the Solana blockchain. Set your budget before you play, understand the house edge, and remember that responsible play is the only winning long-term strategy.
HiLo rewards careful probability assessment. If the current card is a 2, the next card is almost certainly higher — take the safe bet. If it's a 7, it's closer to a coin flip. The real skill is knowing when to cash out. Don't get greedy — a string of 5-6 correct guesses is a solid win.
Set a session budget before you start playing and stick to it. Never chase losses — the odds don't change based on previous outcomes.
The multiplier for each guess depends on the current card. Extreme cards (2, 3, King, Ace) offer lower multipliers for the "obvious" direction but higher multipliers for the risky call.
