Also known as Seven Up, All Fours is an addictive point-trick card game where players compete for points in several rounds, tallying up for the overall championship.
When the dealer turns up the Trump suite in each round, you must develop your strategy to vie for Game points, or fish out and hang your opponent's Jack. Trump cards are the key. You can also accumulate points for playing High Trump, Low Trump, and turning up key cards as the dealer.
You can play against 3 other computer players in Single mode or battle an opponent in the Multi Player mode via Bonjour.
This game seems to have originated in the UK, where it is still very popular in pubs. The 4 player-team version has also become the unofficial national card game of Trinidad and Tobago.
