Jackpot King Prize Lines

Blueprint Gaming trades the usual spinning reels for a grid game in Jackpot King Prize Lines, set inside a classic casino room done up in red leather panelling and gold trim, with an upbeat soundtrack running under the action. Rather than paylines in the conventional sense, the grid mixes red gemstone symbols that carry no value with crown symbols that lock in gold the moment they land.

Play runs in rounds of five spins at a chosen bet, and the aim across those five spins is to build crowns into completed lines — horizontal, vertical or diagonal — across the grid. The more lines completed by the time the round ends, the larger the payout, with the biggest rewards reserved for filling multiple lines across the full width of the grid rather than just one or two.

A gold coin symbol adds a second layer to each round: landing one offers a choice between four objects, each hiding a different reward — extra spins added to the round, extra crowns placed directly onto the grid, or direct access to the Wheel King bonus. Once the five spins are up, players can either bank whatever lines they have completed or pay to keep the round going and add more spins, with the cost scaling to how full the grid already is.

Covering the entire grid in crowns is what triggers Wheel King, a single spin that pays out either a bet multiplier or one of three progressive jackpots — Royal, Regal, and the top-tier Jackpot King itself. The base RTP is 95%, run across 12 available lines with bets from 0.20 up to 10 per round, and a maximum win capped at $250,000. Because the format replaces conventional spinning reels with a grid-building mechanic played out over multiple linked spins, a single round of Jackpot King Prize Lines can stretch out well past a normal slot spin while the crown count builds toward the wheel.
