Symbols and multipliers of the By the Rivers of Buffalo slot machine

By The Rivers of Buffalo features regular and special pictures. Special symbols of the slot have advanced features:

  • Wild symbol — a totem. This icon replaces the common symbols of the slot if it is needed to create a combination. Wins for combos with a joker are doubled
  • Scatter — the picture with a gold coin and the corresponding writing. Three, four and five of these pictures award you regardless of their position on the reels. You will get access to the bonus round of free spins.

Other images create winning patterns when appearing in boxes of adjacent reels beginning from the leftmost reel. To form a combination, you need to get 3-5 identical symbols.

Developers designed eleven regular symbols for the slot. 3, 4 or 5 of them in a row pay:

  • Buffalo — 1, 4 or 6 times your total bet
  • Leopard — 0.8, 3 or 5
  • Eagle — 0.6, 2 or 4
  • Wolf — 0.5, 1.4 or 2.4
  • Bear — 0.4, 1.2 or 1.8
  • A and K — 0.3, 0.8 or 1.2
  • Q and J — 0.2, 0.4 or 0.5
  • 10 — 0.1, 0.3 or 0.4
  • 9 — 0.1, 0.2 or 0.3

When several combinations occur, all winnings are added together. You can transfer your prize to your balance or take part in the double-or-nothing round.


After each successful spin, the Gamble button appears on the right side of the control console. By clicking it, you will confirm your desire to participate in the risk game. Your latest payout will be used for betting.

The picture of a face-down card appears on the screen. The task is to guess its colour or suit. It's up to you to decide what you are going to guess.

The correct guess of colour will double your prize, the correct suit will quadruple it. In both variations, you can continue playing. Each correct guess multiplies your reward by 2 or 4 respectively. The risk game allows you a five-stage round.

However, the wrong guess leads to zeroing of your win. If this happens, you will return to the basic game mode without your latest winnings.
