How to play
Hi-Lo is one of the oldest card guessing games around: a card is face up, and you call whether the next one will beat it or fall under it. This version adds a running multiplier, so every correct call grows your stake until you decide to bank it or a miss wipes it out.
- Choose a chip (10, 50, 100 or 500) and tap the bet spot. Bets go from 10 to 500 credits. Press Start and the first card is turned over.
- Two buttons appear: Higher or same and Lower or same. Aces count as 1 and Kings as 13; suits never matter. A card of the same rank wins for both calls.
- Under each button you’ll see the chance that call is right and what your multiplier becomes if it is, for example “77% · ×1.26”.
- After a correct call you have three options: guess again, press Skip card to replace the current card at no cost, or press Cash out, which shows exactly how many credits you’ll collect.
- A wrong call ends the round and the bet is lost. If you reach 15 correct calls, the game pays you automatically.
A small panel tracks your correct calls, the current multiplier and the cash-out value, and a trail of previous cards shows everything dealt this round, skipped cards included.
Two edge cases are worth knowing. On an Ace, “Higher or same” would always win, so that button is switched off; your only call is “Lower or same”, which needs another Ace. A King works the other way round. In both spots most players just skip.
How the multiplier is built
Every card comes from a full 52-card deck, as if the previous card were shuffled back in each time. So the chance of a call depends only on the card showing: from a rank r, “Higher or same” covers 14 − r ranks and “Lower or same” covers r ranks, out of 13.
Each correct call multiplies your stake by 13 divided by the ranks it covered. At the end, the product is multiplied by 0.97. A few examples:
| Card showing | Call | Chance | Multiplier after one correct call |
|---|---|---|---|
| 4 | Higher or same | 10/13 (77%) | ×1.26 |
| 7 | Either | 7/13 (54%) | ×1.80 |
| 10 | Higher or same | 4/13 (31%) | ×3.15 |
| Queen | Higher or same | 2/13 (15%) | ×6.30 |
| Ace | Lower or same | 1/13 (8%) | ×12.61 |
Two correct calls from a 7 in a row multiply out to about ×3.34. Payouts are rounded down to a whole credit, and the multiplier on screen is rounded down to two decimals.
Strategy
Here’s the honest part: because every step is priced from its exact probability, and the same 0.97 applies at the end, no pattern of calls, skips or cash-outs changes the long-run return. It is 97% of what you bet. Picking the “safe” side doesn’t help, and neither does chasing long shots. The only thing that shaves a little more off is the rounding down to whole credits, which matters most on 10-credit bets. One correct “Lower or same” from a Queen at a 10-credit stake, for instance, is worth 10.5 on paper and pays 10.
So the real decisions are about pace and feel:
- Short, likely steps. From a 2 or a 3, “Higher or same” wins more than 80% of the time. You’ll climb slowly in small increments and cash out often.
- One big swing. Calling a single long shot, such as “Higher or same” from a Jack, multiplies a lot at once. Most of the time it misses.
- Skip the middle. A 7 is close to a coin flip. If you’d rather build on safer calls, skip it; it costs nothing.
- Decide your exit before you start. Since every extra call has the same expected value, cashing out is purely a question of how much risk you want riding on the next card. A fixed target, like “bank at ×3”, keeps sessions steady.
If you like this kind of escalating cash-out decision, Mines uses a grid of hidden tiles instead of cards, and Red Dog asks whether a card will land between two others.
