Jackpot King Deluxe Prize Lines Slot – Free Demo

The Jackpot King pots ride on top of a filling grid

Blueprint Gaming's Jackpot King Deluxe Prize Lines is another instalment in the Jackpot King series. The pots it plays for are progressive, rising on contributions taken from the stakes played, with only the initial seeds funded by the operator. Each one so far has seen the studio draw in wildly divergent mechanics, and for Prize Lines, the developer has delivered their Jackpot King progressives to a grid-filling game for a spin. Players gain from a Coin Modifier, the Wheel King wheel, and some striking winning potential, as well as a held-symbol grid. Every completed line moves you a step up the Prize Ladder, and the ladder is where all the cash prizes come from.

Visits to the grid are feasible on any device where players can choose stakes from the list your operator has set. Total Bet is the only stake control, and what appears in the list depends on the operator and the currency. Finished lines emerge out of the blue to fill the grid at any point. My own balance peaked at 1,004.60, on round 24 of 200. Blend in the Coin Modifier, and the system can be powerful indeed; you won't have to linger long between wins either, as hits arrived at a rate of nearly 1 in 3 rounds across my testing, or 30% of the time, to be precise. Of those 60 paying rounds, 31 came back with less than the 1.00 stake in them.

A 5x5 grid that fills instead of spinning

Prize Lines' action unfolds on a 5x5 grid with no paylines. Blueprint uses the same twelve-line Prize Lines grid in King Kong Cash Prize Lines. Each spin holds the winning symbols in position, and rather than reels, you finish Prize Lines by landing 5 winning symbols in a row, in a column or diagonally. There are 12 Prize Lines in all, 11 of them with a reward on the paytable. The final position you fill always grants at least 2 of them; a round extends to 5 spins, and Extra Spins may be presented for purchase after the fifth.

As for the paytable, the Prize Ladder does the job. At the 1.00 bet the help screens are priced on, 1 line pays 0.20 and 10 lines pay 20.00, so 0.2x up to 20x your stake, and a Full House - the entire grid filled - grants Wheel King instead.

The coin that can hand over Wheel King

Jackpot King Deluxe Prize Lines isn't a game with a heap of extra features, aside from the headline mechanic; in fact, there are two. Top Cat Most Wanted Jackpot King is another Blueprint title feeding the same Jackpot King pot system. A coin can land on any base game spin as the Coin Modifier. You have to make the pick before the game moves on. There you choose 1 of 4 icons for +1, +2 or +3 extra games, for Super, Mega or Ultra extra symbols, or for Wheel King itself. Whichever you take, the coin's position turns into the Win symbol on the grid. Wheel King is the doorway to the big money, and a Full House on the grid or the Wheel King icon from the coin activate it. The jackpots cannot be won anywhere else in the game. It grants one spin of a Tombola style wheel composed of Big Win Multiplier and Progressive pot segments, and what you're spinning for is either a large total bet multiplier or one of the Jackpot King Deluxe jackpots: Jackpot King, the Regal Pot and the Royal Pot. A pot that is won drops back to its reserve amount and starts climbing again.

The Minty Breakdown: One round in two hundred reached the Wheel King wheel, and its 24.00 credits accounted for a quarter of the 94.90 the whole session gave back. Everything else came off the Prize Ladder in pieces of 0.2x to 20x, and 31 of the 60 paying rounds handed over less than the stake that bought them.

Held symbols, and not much else to decide

Prize Lines is a well-crafted game. But you truly need to be into the grid-filling mechanic, because there isn't a lot going on otherwise, and the base game leans on the held-symbol dynamic to supply the bulk of the entertainment to the exclusion of just about everything else. Extra Spins are the only other decision on offer, and their price is shown on the spin button. Since the five-spin format does a fine job of keeping you on your toes, this scarcity of extras isn't an immediate show stopper though. One stake covers all five spins of the round. Lines finish every so often to chalk up a respectable win, and my longest run without one was only 12 rounds. That run ended on round 158. Even Prize Lines can begin to wear thin after a while, if you hunger for variety in your gameplay. My balance closed at 893.90, from a 999.00 start.

The one Wheel King, on round 24

It's fortunate then that the Coin Modifier can land on any spin, and a wheel of progressives is a dependable way to go if a slot ever requires some sort of mechanism to step up the action. Wheel King pays off the initial bet staked, with the cost of any Extra Spins left out of that calculation. Filling the grid to reach the Wheel King wheel is where the progressives are decided, and my own visit there was rather more humble: one Wheel King in 200 rounds, on round 24, paying 24 times the stake and a quarter of everything I won all session. The best round after that was worth 6x the stake, on round 145.

It does go to demonstrate that potential isn't everything, however. Behind the 6.00, the next best rounds paid 3.80, 3.80 and 3.40. Prize Lines is far less absorbing over a long sitting despite the jackpots on the wheel, and even the format is run of the mill. There's nothing amiss. That closing balance was also the session's lowest point. It's just that 200 rounds at a flat 1.00 returned 94.90 of the 200.00 I put through, a 47.4% session return, with the high point arriving on round 24 and nothing to match it afterwards, and Prize Lines' features can definitely deliver under the right conditions. Yet Jackpot King Deluxe Prize Lines might come across a bit dull, despite the promising jackpot figures, if you sense the fill-the-grid format has been played out or want a bit more variety or novelty.
