The Blackjack River formerly known as Rivers is a solitaire tile-placement and set collection standard deck playing card game. Ace through 10 represent river segments, each pip represents a fish. The face cards represent fishermen that can fish at a river segment or from the top of your deck. Play river segments and fishermen to form distributaries of 21 fish off of the Blackjack River. Once the river runs dry, tally your score based on the amount and composition of fish and fisherman in your distributaries. Distributaries with pairs and triples of the same color or suit score more points!
