Detective's Dream Slot by BigPot Gaming

At 85x per entry, the buy option drops you straight into free spins - and that's where the one mechanic that matters kicks in. When the bonus starts, a random high symbol gets designated as the "extension symbol." Binoculars, revolver, magnifying glass, pocket watch, boot, or the feather quill with its ink bottle - whichever gets picked will expand across an entire reel whenever it lands as part of a winning combination on that reel. So if the magnifying glass is selected and three magnifying glasses connect across reels 1 through 3 on any of the 20 paylines, those symbols stretch to fill their reel positions and payouts calculate on the expanded result.

Ten free spins to start, and the retrigger condition is what gives the round its ceiling. Two or more Scatter Wild symbols during free spins add 10 more spins AND select a second extension symbol. Hit the retrigger again and a third symbol joins. Each new extension symbol stacks onto the previous ones, so by the third wave you could have three different high symbols all expanding on wins simultaneously. The interaction between multiple expanding symbols across 20 paylines is the only path to the 4,000x cap - the base game with its single Wild substitution and no multipliers won't get you there.

Sepia-toned detective tools against a muted damask wallpaper, brass gears and cogs built into the reel frame, payline markers in dark metallic boxes on both sides. Everything is rendered in warm browns and golds with that steampunk brass-and-leather look - ornate Victorian card royals (A, K, Q, J, 10) take up most of the reel real estate while the detective instruments sit above them in the paytable. The golden pocket watch Wild is the most detailed symbol on the grid, though it only substitutes without carrying a multiplier.
