What Blueprint makes

Online slots, many of them sold in several forms of the same game: a standard version, a Jackpot King version, sometimes a Megaways edition. Blueprint also makes branded slots built around films and TV series, such as Game of Thrones and The Goonies.

How Jackpot King works

Jackpot King is Blueprint's progressive jackpot system. Blueprint says cash prizes or progressive jackpots can be won on any spin in Jackpot King games. Its game pages show the RTP of these versions as a base figure "+ JK %": part of the return comes from the jackpot, which most players never win. In practice, that means the everyday return of a Jackpot King game is lower than the headline total. Our progressive jackpot slots guide explains why.

Notable games

The Goonies Quest for Treasure 3 (2026). A branded 4,096-ways slot with cash symbols on reels 1 to 6 that pay when a Collect symbol lands on reel 1 or 6, a feature trail and chests that upgrade the bonus. Listed top win 10,000x the bet.

RTP versions, in Blueprint's own words

Blueprint publishes a separate game ID for each RTP setting. The casino decides which one you get.

Game	RTP versions listed by Blueprint
Fishin' Frenzy	90%, 92%, 93%, 94%, 96.12%
Game of Thrones	90%, 92%, 93%, 94%
King Kong Cash Even Bigger Bananas 4	92%, 93%, 95%
The Goonies Quest for Treasure 3	90%, 92%, 93%, 94%
The Goonies Megaways Quest for Treasure Jackpot King	91.5%, 92.5%, 94.5%, each plus the jackpot contribution

Here is what the Fishin' Frenzy range means in pounds. On £500 of total bets, the expected loss is about £19 at 96.12% and £50 at 90% (our calculation: total bets × (100% − RTP), a long-run average). Same game, more than twice the expected cost. Open the paytable or help screen before you play and look for the RTP. Our RTP and volatility guide explains the maths.
