Slots O' Luck Free Spins is an Inspired Gaming video slot with a cheerful Irish theme. The game has a standard 5×4 grid and 40 paylines. The game offers medium volatility and a RTP of 95%, which is slightly below the industry average. Players can bet between $0.20 and $100 per spin, with the maximum win capped at 2500 times the bet.
Slot symbols include the classic A-10 Royals and three premium gems (emerald, diamond and ruby). All symbols land in stacks and wins require at least three of the same symbol to land on adjacent reels. There's also a wild symbol that appears on reels 2, 3 and 4 and substitutes for other symbols to complete winning combinations.
The main bonus feature is the Free Spins round. Players can trigger this feature in two ways: by landing three Scatter symbols on reels 1, 3 and 5 during the base game, or by gambling their winnings in the Gamble feature. The Free Spins round awards eight free spins with only wild and highest-paid gem symbols on the reels, increasing the chances of landing bigger wins.
The Gamble feature allows players to take a risk and potentially increase their winnings or win additional free spins. After a winning spin, players can activate the Gamble feature. Two wheels appear, one offering the chance to multiply wins by varying amounts and the other offering the chance to win free spins. Landing on a green segment of the wheel wins the prize, while landing on a red segment forfeits the prize or gamble for free spins. This feature can be repeated until the maximum prize or free spins are reached.
Finally, the Spin Chance feature is automatically activated when a player's balance falls below the current bet amount. This feature offers a chance to wager the remaining credits on one additional spin at the previously selected bet amount. Similar to the Gamble feature, a wheel determines if the player wins the extra spin.
