Thrill HiLo review: 99% RTP, 1,000,000x max win, 287,419 public bets tracked

Thrill HiLo is a card-chain game at a 1% house edge, so the declared RTP is 99%. You call whether the next card is higher, lower or the same, and every right call grows the multiplier. Chains run up to 1,000,000x, and one round pays $500,000 at most.

How Thrill HiLo pays

Cards rank from Ace (1) to King (13), and each draw is a fresh pick from a 52-card deck. On a 2 to a Queen, you call Higher or Same, or Lower or Same. On an Ace you call Same or Higher, and on a King, Lower or Same. Same always wins 1 time in 13, so it pays 12.87x as a first call.

Thrill HiLo math

Your first call pays 1 divided by its chance, times 0.99. Every later call multiplies the running total at fair odds. So the 1% comes off once per round, however long the chain runs. Higher or Same on a 7, for example, wins 7 times in 13.

Thrill HiLo payout cap

The $500,000 cap means a 1,000,000x chain pays in full only on a 50-cent bet. At the $20,000 max bet, the cap works out to 25x your stake. Each card comes from Thrill’s HMAC-SHA512 seed hash, and Thrill publishes the odds and the code.

Thrill HiLo vs Gamdom Hilo

Gamdom Hilo has the same name and a different format. It reveals a running stream of cards on a countdown. You bet each card on its own, on color, a rank range or higher and lower, and nothing chains. It pays 100% RTP on your first $5,000 wagered, then 99%. Pick Thrill HiLo if you want to build a multiplier one card at a time.
