At the biggining of the hands, each player set a $-5 to $+6 for each suite's value of cards.
There are two decks. One for Suits. One for Ranks.
Players plays a set of both cards. Yes, you can combine Suite and Rank.
Trump is automatically determine by lead suite. For example to 3 players game, if an Airplane are led, Ship is trump for that trick.
You must follow the lead Suit if you can. If tie, earliest card wins.
I played this game with my wife and 6 years old daughter.
We enjoyed very much.
Rank and Suit combination is very interesting point.
Lead and Trump combination is another point.
Deciding Suit card's value is change mechanics of hand.
We think, this is a interesting tricky game.
