Stake Hilo: rules, probabilities and cash-out

Stake Hilo is a card-guessing game from the Stake Originals range. The game deals one card face up from a standard deck. You predict whether the next card will be higher or lower, and each correct prediction multiplies your bet. You can cash out after any correct guess, or keep going for a larger multiplier. One wrong guess ends the round and loses the stake.

The appeal is control. Unlike Dice or Limbo, where you choose a target once, Hilo asks you to make a series of decisions, and you choose when to take the money. That control is real, but it is also an illusion in one respect: the next card is already set by the provably fair draw, and no sequence of choices changes the 1% house edge.

1. Set your bet amount.
2. Press Bet to be dealt a starting card.
3. Choose Higher or Same, or Lower or Same. The game shows the multiplier each button would give and the chance of that guess being correct.
4. Reveal the next card. If you were right, your multiplier grows. If you were wrong, the round ends.
5. Cash out whenever you like after a correct guess, or continue.

The Skip button swaps the current card for a new one without risking your bet. Check the game for any limit on skips. Skipping changes the card you face, not your multiplier, and each new card is as random as the last.

On most cards both buttons include "same". If the next card has the same rank as the current one, either guess wins. The Ace and King are the exceptions, so read the buttons there. That is why the percentages for higher and lower from a middle card add up to more than 100%.

Thirteen ranks appear equally often, so the chance of each guess depends on the current rank. With ranks counted 1 to 13, the chance that the next card is higher or the same from rank r is (14 − r) / 13, and lower or the same is r / 13, before the special handling at the Ace and King.

The payout for a guess is roughly 0.99 divided by its chance, which builds in the 1% edge. Some examples:

These figures use ranks 1 to 13 and are calculated from the maths, not copied from the game, so check the buttons for the exact numbers, especially on the Ace and King.

Chained guesses multiply. Three 80% guesses in a row have a combined chance of about 51% and a combined multiplier of roughly 1.9×, which is again the same 99% return.

When skipping helps

Skipping costs nothing, so a player who dislikes a starting card can swap it. It does not improve your odds on the next card, because each dealt card is independent. What it does is let you avoid a card whose buttons both show uncomfortable choices, such as a very high or very low card where one guess is nearly certain and the other very unlikely.

When to cash out

Cash-out is the only genuine decision in Hilo. Because every guess is priced at 99% of fair value, cashing out early and continuing are mathematically equal in expectation. The difference is variance: cashing out after one or two safe guesses gives frequent small results, while chasing a long chain gives rare large ones and many full losses.

A useful habit is to decide your target multiplier before you press Bet, rather than reacting to how the last card felt. That is the same idea as the planning approach in the Mines strategy guide.

The Auto tab lets you pre-set a rule such as "always guess the more likely option" and a cash-out point, then runs rounds automatically. You can also set Number of Bets, On Win and On Loss changes, and Stop on Profit and Stop on Loss limits.

Auto removes the thinking time, so it removes the natural pauses where you might stop. Set a finite number of bets and a stop-on-loss, and watch total wagered rather than the balance alone. See the glossary for what turnover means for VIP progress.

Always pick the more likely side

This raises your chance of surviving each step and lowers the payout equally. The expected return per step is still 99%.

Waiting for extreme cards

A low card makes "higher" likely and a high card makes "lower" likely. That is accurate, but the payout drops by the same proportion.

Counting cards

Each round is dealt independently from the provably fair seeds. Cards already seen in earlier rounds do not remove anything from the next deal, so counting has no value here.

Raising the stake after a loss

A losing streak does not make a win more likely. It makes the next loss cost more.

Hilo uses Stake's provably fair system. You see the hash of the server seed before you play, you can change your client seed, and each card is derived from server seed, client seed, nonce and the card's position in the sequence through HMAC-SHA256. After rotating seeds, Stake reveals the old server seed so you can recompute every card from your history. The provably fair guide walks through it.
