Treasure Box series
Treasure Box Kingdom set IGT's Treasure Box line in motion in 2022, fixing its formula around a 5x3 screen, 243 ways and a hold-and-win collection bonus. Later Treasure Box slots preserve that chassis while changing volatility, collection rules and the kind of prize pursued inside the bonus.

Treasure Box slots keep the chassis and move the pressure
Kingdom is the high-volatility foundation, pairing its hold-and-win round with a cash collector, free spins, multipliers and a 10,000x maximum. Treasure Box Dynasty keeps the 5x3, 243-way layout and the same ceiling in 2023, but drops to medium volatility and adds symbol collection, extra free spins and a dragon-led Asian theme. That makes Dynasty a pacing revision rather than a structural sequel.
Treasure Box Clans retains the 5x3 and 243-way base in 2024 but narrows the visible feature package to hold-and-win play, wilds and fixed jackpots. Its 96.17% RTP also separates it from Kingdom's 94% and Dynasty's 93.17%. Across the line, the treasure skin moves from Egyptian fruit and gems to dragons and Viking clans, while the reusable core remains a compact multiway screen feeding a locked-prize bonus.
