I finally got a chance to play Canyon, which was a gift to me from my Germany-refugee friend, Russ. Six of us started the game.
We all enjoyed the five suits. Five suits made it much less likely that a high off-trump card would not get trumped. That is, until you get to the final trick that you DON'T want.
I was lodged in 3rd place approaching the rapids. By luck (it was each of our first times playing the game) I was able to take two tricks for the +3 bonus and launch my canoe far into the rapids. This shot me to the lead and I was able to play safe to get home. My fellow players enjoyed the game so much that they played until the 5th and 6th places were determined!
