A free program for Android, by John Goacher.
The Bridge Solver app is a powerful tool for solving bridge problems. It combines the power of the interactive card game with the latest computer technology to solve your problems in no time.
The application is based on the same concept as the classic card game. The main difference is that in the Solver version, the cards are replaced with digital symbols and the game is played with a computer. This makes the game much easier to play and easier to understand.
It is a very versatile tool. Not only can it be used to find the best line of play, it can also be used to find the best contract for any hand.
