Play Hi-Lo for free: guess whether the next card is higher or lower, grow the multiplier with every right call and cash out any time. Skip a card you don't like.
A card is turned face up. Guess whether the next one will be higher or lower. Every right call grows your multiplier; a wrong one ends the round and takes your bet.
Aces are low: A, 2, 3 ... 10, J, Q, K. Every card is dealt from a full, freshly shuffled 52-card deck, so each rank is always 1 in 13, whatever came before. Counting cards gets you nothing here.
A round can turn at most 199 cards after the first. If you get that far, it cashes out for you (or, if you never made a guess, it hands your bet back).
Each right call multiplies your run by one over its chance: a 1 in 2 guess doubles it, a 12 in 13 guess adds about 8%. The house edge, 5%, is taken once off the whole run, not off every guess.
That makes the expected return 95% of your stake whatever you pick, however many cards you skip, and whenever you cash out. Multipliers and payouts are rounded down to the cent.
The two guesses on each card (≥ higher or same, ≤ lower or same, > higher, < lower, = same), how many of the 13 ranks win them, and what a first right call pays:
A
> 12/13 → 1.02x = 1/13 → 12.35x
2
≥ 12/13 → 1.02x ≤ 2/13 → 6.17x
3
≥ 11/13 → 1.12x ≤ 3/13 → 4.11x
4
≥ 10/13 → 1.23x ≤ 4/13 → 3.08x
5
≥ 9/13 → 1.37x ≤ 5/13 → 2.47x
6
≥ 8/13 → 1.54x ≤ 6/13 → 2.05x
7
≥ 7/13 → 1.76x ≤ 7/13 → 1.76x
8
≥ 6/13 → 2.05x ≤ 8/13 → 1.54x
9
≥ 5/13 → 2.47x ≤ 9/13 → 1.37x
10
≥ 4/13 → 3.08x ≤ 10/13 → 1.23x
J
≥ 3/13 → 4.11x ≤ 11/13 → 1.12x
Q
≥ 2/13 → 6.17x ≤ 12/13 → 1.02x
K
< 12/13 → 1.02x = 1/13 → 12.35x
Skipping is free, so you can wait for a card you like the look of, but no card is a better bet than another: every guess is priced on its own true chance.
