Horses on twenty lines

The artwork follows the American frontier, with cowboys and horses taking center stage. Beneath it sits a standard 5-reel layout with 20 paylines, which most players will recognize immediately. The in-game paytable holds the symbol values.

Booming Games has a varied catalogue, from Burning Classics 2 to Cash Pig 2, all gathered on the Booming Games page.

Low RTP, high volatility

At 95.4%, the long-run house edge is 4.6%, which is noticeably wider than the 4% a 96% slot implies. That is an average over millions of spins; it does not tell you how a single session will go. The RTP guide goes through the arithmetic.

High volatility means big payouts, if they come, are rare, and long losing runs are normal. Pairing that with a below-par RTP makes careful budgeting more important here than in a medium-volatility game. See the volatility guide for the full picture. Your casino chooses which RTP setting it runs.

Free spins and the buy option

Wilds help form winning lines, free spins act as the bonus round, and the bonus buy skips ahead to it for a multiple of your stake. The public material does not describe the free-spin mechanics, so none are claimed here.

A purchased bonus is expensive, and with high volatility a single buy can end without much return. It carries no better odds than regular play. Set a firm limit, never chase losses, and play only if you are 18 or older.
