Shaker Club Slot by Yggdrasil Gaming

Hit Free Spins on three scatters and the round opens with a question. Take the X3 starting multiplier and play out the 8 spins, or gamble it for a chance at X10. Win that and you can gamble again for X25. Lose either gamble and the entire bonus is forfeit - no spins, no consolation, the trigger gone. Yggdrasil rarely puts a forfeit-everything choice in front of a player who just earned a feature, and most won't take it. The math is genuinely interesting on a marginal trigger though, because four scatters opens at X10 and five at X25 directly, so the only path from a cheap 3-scatter pull to a top-tier session is through the gamble.

Once inside the round the multiplier is the entire engine. Whatever value you start at climbs +1 per spin completed, with another +1 added for every Free Spins scatter that lands during the round (only on reels 2 and 4 in bonus mode, and they no longer add spins). The cap is X250, and once it hits that ceiling the remaining spins continue at X250 without resetting. An X25 starting tier with a few mid-round scatters can comfortably saturate the cap by spin 5, leaving three spins of X250 still to play out. That ceiling and the 10,000x payout cap pull in opposite directions on long runs.

Base play swaps the climbing multiplier for a Random one. A golden cocktail shaker drops in unannounced on a paying spin and stamps a value up to X250 on the total win. The shaker icon parked at the upper-left of the reels shows the active multiplier when one is live. Wilds appear on reels 2-5 only, never on reel 1, and substitute everything except the Free Spins scatter.

The buy menu is a clean two-tier setup. The 100x bet entry rolls a random starting multiplier weighted to mirror the 3/4/5-scatter natural distribution. The 600x bet tier guarantees the X25 maximum tier from the first spin and skips the gamble decision entirely. 600x is the only path to a guaranteed top-tier opening hand from cold.

The cabinet is staged inside an upscale cocktail lounge at midnight. Silhouetted patrons line a wooden bar counter, shelves of liquor bottles glow purple and teal in the back, and the SHAKER CLUB sign burns hot pink above the reels with two bartender icons either side. Highs are photoreal cocktail glasses (red martini, blue tropical, lime mojito, orange garnish) and lows are stylised neon card suits. The Wild art is a portrait of a female bartender with WILD stamped pink across the front. A 1980s Miami neon-noir vibe rather than the studio's recent stage-spotlight or Asian-noir cabinets, and closer in mood to Neon West than anything else in their Boost lineup.
