Hundred or Nothing series: IGT's single-line high-stakes formula
The Hundred or Nothing series is IGT's single-payline Vegas franchise, built around free spins, wilds, multipliers and a 100x maximum. Hundred or Nothing reduces that idea to a 3x1 layout, giving every result one direct line to resolve. Its listed RTP is 92.55%, with bets ranging from 0.10 to 100.

Hundred or Nothing High Stakes expands the screen to 5x3 but keeps one payline and the same 100x ceiling. The sequel's listed RTP rises to 93.97%, its upper bet limit doubles to 200, and its feature set carries a high-volatility label.
High Stakes therefore enlarges the presentation and stake range without changing the franchise's central constraint. Both games make one line carry the full outcome; the sequel applies that stripped-back rule to a larger reel window and a more explicitly severe risk profile.
