Spades Plus Card Game: Play and Win Against Tough Opponents | Best Android Spades Game by Zynga
Two main challenges before the developers who want to create a game like Spades Plus are,
1) writing codes that quickly calculate the score
2) an algorithm that shuffles the card well
Now most of the android games I played faired well in first challenge. If you extract the apk of an existing game and go through their codes, you'll see, they are more or less the same. It was the second challenge where the best of the developers struggle.
Before Spades Plus I played Ace of Spades multiplayer. Great graphics. Fast. Detailed and accurate scoring. But the shuffling is so bad, it's almost predictable. You rarely get more than four cards in each suit.
In this particular challenge Zynga beats all the rest. The shuffling is ultra-realistic. It almost feels like you're sitting on a real table.
