St Louis 1904

Blue Guru Games builds St Louis 1904 around the chaotic 1904 Olympic marathon, setting its reels against a sun-bleached, dusty course dotted with period detail — insects, thermometers, worn signage — that hints at how brutal that race really was. Five reels and three rows carry the action across 10 fixed paylines.

Low-value symbols take the form of water buckets, apples, thermometers, shoes and bottles, paying 5x to 20x the stake for five matching icons on a line. Money Medal symbols and four runner-themed characters sit above them, worth 50x to 200x the stake for a full line of five.

During free spins, a Wild Collector symbol occupies every reel and substitutes for anything except the scatter. Outside that round, landing three Money Medal symbols on the leftmost reel can set off Money Medal Respins, sending reels two through five spinning again in search of extra Money Medals to complete an instant cash payline; Money Medals themselves are worth anywhere from 2x to 5,000x the stake, and in free spins one pays out the moment it shares the grid with a Wild Collector.

Three, four or five scatters open the Free Spins round for 10, 15 or 20 spins in turn. Two scatters landing in the base game can also spark a smaller consolation effect — either the scatters shift down a row while the rest of the grid respins, or a Whirlwind effect conjures a fresh scatter onto a random reel. Before a free spins round begins, as many as five reel modifiers can be dealt at random: extra Money Medals or Wild Collectors seeded onto the reels, more of the low-value Car, Rotten Apple and Dog symbols, a starting multiplier locked at x2, or two bonus spins added both to the starting count and to each retrigger.

Once the round is under way, every Wild Collector sweeps up the value of any Money Medal it touches and also feeds a running collection tally of its own; that tally hands out extra spins and a climbing multiplier — x2, then x3, then x10 — each time it completes another full cycle of four, with the current multiplier applying to whatever Money Medals get collected next. If a spin ends with Wild Collectors showing but no Money Medals on the grid, the Rotten Apples effect can turn other symbols into fresh ones; the opposite case, Money Medals with no Wild Collector present, can bring a new one in through the Car feature, while the Pack of Dogs effect separately seeds extra Money Medals onto empty positions.

A bonus buy menu skips straight to the feature: 70x the stake guarantees three scatters and 10 free spins at a 96.22% RTP, 145x guarantees four scatters, 15 spins and one modifier at 96.15%, and 270x guarantees five scatters, 20 spins and two modifiers at 96.16%. Away from the buy screen, the base game runs at a 95.95% RTP, rated high volatility, for stakes between 0.10 and 50 a spin; the outright ceiling on any single spin is 10,000x the stake.
