Wild West Duels is a 5-reel and 5-row online slot game from Pragmatic Play that is set in a dusty western town. The game features multiple bonus rounds and innovative mechanics that make it stand out. Here are some features and mechanics to expect from the game:

- Expanding Wilds: Wild symbols can expand at random to fill the whole reel, which can lead to some big wins. When this happens, a shootout takes place, and the winning gunfighter's multiplier determines the Wild multiplier, which can reach up to x100.
- Three Bonus Rounds: The game features three different bonus rounds that offer players exciting opportunities to win big:

1. Beer Game: Trigger this bonus round by landing three or more Beer Game scatters in view. This round comes with 10 free spins and Beer mug wilds that become sticky for the duration of the round. The wilds come with multiplier values of x2 or x3 and can add up if more than one wild is part of the same win. Expanding Wilds do not appear in the Beer Game, and there is no retrigger.

2. Duel Game: Trigger this bonus round by landing three or more Duel scatters in view. This round also comes with 10 free spins, and every spin guarantees at least one wild in a random position. Wilds can expand to become dueling multiplier wilds in this feature. There is no way to retrigger.

3. Lost Relics: Trigger this bonus round by landing at least three Lost Relics scatters in view. This bonus round gives you three free spins after selecting nine picks from 25 available shovels. The picks increase the win multiplier and/or the amount of guaranteed wilds. Each pick can award up to +5 wilds or +1, +2, +3, or +5 added to the multiplier tally. The accumulated amount of wilds per free spin, and the achieved multiplier boosts all wins. This round has no retrigger possibilities, and players cannot get expanding dueling wilds.

- Pay Symbols: The game's premium symbols pay between 5 and 20 x your stake for 5 of a kind wins. There is also a gold bag Wild that can appear anywhere to substitute for pay symbols and help complete or improve wins.

- Bonus Buy Menu: Available only for non-UK players and those who are eligible, the Bonus Buy menu allows players to purchase all three of the bonus rounds. The Beer Game costs 100x, the Duel Game costs 200x, and the Lost Relics feature costs 400x. The RTP remains the same for purchased bonus rounds.

Overall, Wild West Duels is a fun and innovative online slot game that offers multiple exciting bonus features and mechanics to keep players engaged.
