Spree has added 3 Big Oinkers Mr. Riches, a Hold & Win slot from Koala Games, as an exclusive game in its sweepstakes casino lobby. The operator announced on X on Oct. 28 that the title was live, describing its Hold & Win action as available exclusively at Spree.
The release gives Spree a Koala Games title carrying the Mr. Riches character that rival sweepstakes casinos cannot list for now. Spree did not say how long the exclusivity arrangement would last. The game joins a lobby that Spree says contains more than 3,000 slots and receives new titles weekly.
Koala Games lists the title as high volatility with a maximum win of 5,500 times the stake. Some third-party slot databases show a 2,000x maximum win, but the developer’s 5,500x figure is the stated maximum on its own listing.
The developer publishes four mathematical versions, with return-to-player settings ranging from 90.33% to 96.33%. It does not identify which version runs at Spree, so players would need to consult the game’s information screen for the applicable RTP.
The difference matters over the long run. At the highest listed rate, 100 Spree Coins of play has a theoretical return of 96.33 Spree Coins, compared with 90.33 at the lowest rate, a gap of 6 Spree Coins. Those figures are long-run averages rather than predictions for an individual session, and high volatility can produce results substantially above or below the theoretical return.
The Hold & Win bonus begins when a Blue, Green or Red Pig lands. The Blue Pig applies random x2, x3 or x5 multipliers to every prize; the Green Pig raises the respin count to four; and the Red Pig opens a second reel set, doubling the on-screen potential.
During the feature, filling a column collects its prizes and clears space for more symbols. A column filled for the first time awards one letter, and collecting G-R-A-N-D triggers the Grand jackpot. The double-reel version can award the Grand jackpot twice in a single feature.
Koala Games also lists Perceived Persistence, Jackpots and a Buy Feature among the title’s functions. Players can first use Gold Coins, which have no monetary value, before playing with Spree Coins; prizes may be redeemed under Spree’s terms. The release illustrates how exclusive games have become a means of differentiation in increasingly crowded sweepstakes-casino lobbies.
