The Ribeirinhos are a group of native South Americans who live by rivers. Join these happy-go-lucky folk for a game of river bingo. You’ll get to watch the sun set behind huts teetering on stilts, and see a man paddle listlessly in a boat. The payouts are just as enticing as the game’s graphics; 11 patterns trigger wins, and one pattern triggers a bonus round that’ll have you collecting coins as you pick up baskets of fish. If you find yourself struggling to land these wins, take advantage of the game’s Extra Ball feature. You can buy up to 13 spare balls when you’re one number short of a winning pattern.
