Stadium of Riches by Play'n GO features a groundbreaking expanding symbols mechanic where you can stack up to 9 different expanding symbols during free spins. When trophy wilds land in groups of three or more, they trigger the free spins feature and randomly select expanding symbols that fill entire reels when they appear.
The golden boot symbol pays 5,000 coins for five-of-a-kind, matching the wild trophy payout. During free spins, expanding symbols create massive win potential across the 5x3 grid with 10 selectable paylines.
5 Reels × 3 Rows × 10 Paylines
The expanding symbol mechanic in Stadium of Riches differs significantly from standard free spins features. When three or more wild trophy scatter symbols appear anywhere on the reels, they trigger the free spins round and one symbol is randomly chosen as the expanding symbol. This chosen symbol expands to fill entire reels when it appears, paying on any position rather than requiring left-to-right alignment.
The unique aspect of Stadium of Riches is the ability to activate up to 9 different expanding symbols. Each time you re-trigger free spins by landing three or more scatters during the bonus round, an additional symbol becomes an expanding symbol. With a maximum of 9 expanding symbols active simultaneously, virtually every symbol on the reels can expand to fill entire columns, creating unprecedented win potential across the 10 paylines.
The wild trophy and golden boot both pay 5,000 coins for five matching symbols, making them the highest-value symbols. The football pays 1,600 coins for five-of-a-kind, while goalkeeper gloves and the referee whistle both award 600 coins. Card symbols range from 120 coins for five Aces or Kings down to 80 coins for five Tens, Jacks, or Queens. All line wins multiply by the coins staked per line, while scatter wins multiply by the total bet amount.
After any base game win, Stadium of Riches offers a gamble feature where you predict either the color or suit of a face-down playing card. Choosing the correct color (red or black) doubles your win with 50% odds, while correctly guessing the specific suit (hearts, diamonds, clubs, or spades) quadruples your win at 25% odds.
The gamble feature has two built-in limits: you can gamble a maximum of 5 consecutive times, and winnings are capped at 2,500 coins per gamble session. Previous cards are displayed at the bottom of the gamble screen, allowing you to track which cards have already been drawn, though this does not technically alter the odds as each draw appears independent.
Stadium of Riches allows adjustment of three betting parameters: coin value ranges from 0.01 to values like 0.20, coins per line can be set from 1 to higher amounts, and paylines can be adjusted from 1 to 10. The total bet equals coin value multiplied by coins per line multiplied by active paylines. At maximum settings with 10 active paylines, a single spin bet could range from modest amounts to several currency units depending on your coin value selection.
Stadium of Riches uses 10 distinct payline patterns across the 5x3 grid. Lines 1-3 are horizontal straight lines through the top, middle, and bottom rows. Lines 4-5 form V-shaped patterns. Lines 6-7 create zigzag waves. Lines 8-9 form M and W shapes, while line 10 creates a diamond pattern through the middle positions.
Win Rules: All line wins multiply by bet per line. Scatter wins multiply by total bet. Wins pay left to right except scatter symbols which pay on any position. Only the highest win per line is paid.

Features autoplay with customizable stop conditions, spacebar spin activation, adjustable game speed, and keyboard navigation for motor impairment accommodation.
Stadium of Riches includes comprehensive autoplay functionality allowing 10, 20, 50, 75, or 100 automatic spins. Stop conditions include triggering on any win, stopping if free spins are won, and three slider-based limits: if a single win exceeds a set amount, if balance increases by a specified amount, or if balance decreases beyond a threshold.
The settings panel provides toggles for sound on/off, auto-adjust bet (automatically reduces bet if balance is insufficient), fast play mode (accelerates reel animations), and spacebar to spin (enables keyboard shortcut). The turbo button on the main screen provides quick access to accelerated gameplay without entering settings.
For visually impaired players, all buttons and controls are keyboard accessible with logical tab order. Colorblind players benefit from symbols identified by distinct letters and numbers rather than color alone, though symbols do use color coding (A=red, K=orange, Q=purple, J=green, 10=blue). Motor impairment accommodations include large clickable buttons, autoplay to reduce repeated clicking, and keyboard controls eliminating mouse precision requirements.
The stadium setting creates atmospheric immersion with floodlight effects, crowd silhouettes, and a football pitch visible at the bottom of the screen. The symbol set includes authentic football equipment: a World Cup-style golden trophy serving as the wild, a professional golden boot with white and gold coloring, a red and white football with star panel design, neon green and yellow goalkeeper gloves, and a silver referee whistle with gold attachment ring.
Visual effects enhance the football atmosphere through stadium lighting creating blue-tinted atmospheric effects, goal posts visible on screen edges, and crowd silhouettes with raised arms suggesting celebration. The metallic 3D title treatment with golden and silver gradients evokes trophy aesthetics, while the green felt surface in the gamble feature maintains the sports theme through card table presentation.
Stadium of Riches demonstrates Play'n GO's technical capabilities through smooth reel animations, expanding symbol effects that fill entire reels, win highlighting with golden glow effects, and responsive controls across desktop and mobile devices. The game maintains the developer's reputation for mathematical model integrity, with stated payouts matching actual performance in certified testing.
