Jackpot King is Blueprint Gaming’s flagship progressive system, bolted onto dozens of popular UK slots — 7s Deluxe, King Kong Cashpots, Fishin’ Frenzy and the Deal or No Deal series among them. Its claim to fame is delivery: documented UK payouts include a £5.4 million King Kong Cashpots win in January 2023 and £4.3 million on Deal or No Deal Bankers Boost in October 2024, making it arguably the most productive non-Microgaming network for British players.

How the Wheel King works

Land five Jackpot King overlay symbols across the reels of any participating game to enter the bonus ladder. Climb far enough and you reach the Wheel King — a wheel whose top segment awards the network-wide Jackpot King pot. Lower rungs pay the smaller Royal and Regal pots, so entries frequently return something even when the main prize escapes you.

Because the overlay system sits on top of ordinary slots, you choose your base game by taste — fruit machine, fishing or game-show branding — while chasing the same shared prize pool from any of them.

Value and volatility

Base-game RTPs across the family sit around the 95% mark, a little below premium standalone slots, with roughly 1% feeding the pools. The pot cycle is healthy: the network pays multi-million prizes far more often than most rivals, though as always each spin’s odds are random and unaffected by pool size.

Our verdict

The best progressive network for players who want variety: dozens of familiar base games, a proven multi-million payout record and a bonus ladder that pays something on most visits. Check each title’s RTP before you settle in — they vary.
