Stadium of Riches: Play'n GO's Sports-Themed Expanding Symbol Slot

How the Reels and Paylines Work

With 10 fixed paylines, every spin covers the same set of lines, so there is no payline selection to manage. Wins are formed by landing matching symbols from the leftmost reel rightwards along an active line. The trophy is the symbol to watch: it acts as both wild and scatter, substituting for regular symbols to complete line wins and triggering the bonus when enough of them land. The compact 5x3 layout keeps the game readable and the pace brisk, which suits the high-variance maths underneath.

Free Spins and the Expanding Symbol Feature

The heart of Stadium of Riches is its free spins round. Landing three or more trophy wild/scatter symbols awards 8 free spins. At the start of the feature, one regular symbol is selected at random to become an expanding symbol for the duration of the round. Whenever enough instances of that symbol land to form a win, it expands to fill its entire reel and pays across all 10 paylines, even when the positions are not adjacent.

The feature can build from there. Additional trophy symbols landing during free spins retrigger the round and add another expanding symbol to the mix, stacking up to a total of nine expanding symbols. With multiple symbols all capable of filling reels and paying across every line, the later stages of a well-fed free spins round are where the biggest payouts come together.

RTP and Volatility

Stadium of Riches ships with a default RTP of 96.58%, which sits comfortably above the industry average. As is standard for Play'n GO, operators can also choose from lower-return configurations (94.51%, 91.51%, 87.56% and 84.55%), so it is worth checking the paytable of whichever casino you play at to confirm the version on offer.

The volatility is high. In practice that means a relatively frequent stream of modest base-game hits punctuated by longer waits for the free spins round, where the real value of the game is concentrated. If you prefer steady, low-variance play, this is not the title for you, but the expanding symbol mechanic gives the bonus genuine upside.

Max Win and Betting Range

The maximum win is capped at 5,000x your stake, a figure realistically reached through a strong free spins round with several expanding symbols paying across all lines at once. Bets run from 0.10 per spin, covering casual players and higher rollers alike. There is also an optional Gamble feature on wins, letting you double your payout by guessing a card color or quadruple it by picking the correct suit, a classic Play'n GO touch for players willing to take the risk.

Play Stadium of Riches on Mobile

The 5x3 grid scales cleanly to smaller screens, and the touch controls for setting your bet, spinning and opening the paytable are straightforward. All features, including the expanding symbol free spins and the Gamble option, work identically across devices.

Should You Play Stadium of Riches?

Stadium of Riches is a focused, high-volatility slot that leans entirely on its expanding symbol free spins to deliver excitement. The 96.58% default RTP is fair, the 5,000x ceiling is solid for this style of game, and the ability to stack up to nine expanding symbols gives the bonus real teeth. It is a good fit for players who enjoy chasing feature rounds rather than constant small wins. Try the free demo at the top of the page to see how the expanding symbols play out.
