Great Fun!

I enjoy having the ability to play bridge 24/7!! I play with friend online three times a week with friends I’ve met online. But, I enjoy being able to practice whenever I wish… on my own.

Well done, app designers! Plus, anyone can reach out to them… via email and they are quick to get back to you with answers, support. It’s the best app online!!

AI Imbalanced

Another Update:
AI’s bidding is getting more atrocious, which I didn’t think was possible! Oh, and, it cheats! West bids 4 Clubs while holding a hand of 5 points and two lowly cards in clubs. East meanwhile has 7 cards in Clubs including A, K & J, which West seems to be aware of. I doubled and took them down -3.
Similar scenarios have happened so often that I’ve given up taking screenshots since it doesn’t seem that the Devs have any interest in improving the AI. Time to uninstall and move on.

Update: I’m truly glad to know that you are dedicated to improving the AI. I’ve taken a bunch of screenshots that I can email you, if that will help. I’ll try and report the hands via the button but, I don’t think it’s possible after the hand has been played. That button is not accessible when Shark shows on the pop up screen what it would have bid and scored.
Rather than playing online, which depends on the schedule of others, I prefer to play against the AI. I would be happy to pay if I saw some real improvements with the AI’s bidding algorithm.
Thanks for your response.

I much preferred the previous version of this app. The “improvements “ to AI in this version are a joke!
Even on the conservative setting, the Robot makes very aggressive bids for my partner North, invariably leading to a loss.
What’s most galling is that, at the end of the game, Shark’s own analysis is that North should have bid differently!

Developer Response ,


The AI have not been neglected, for us that is the fun part of this project . We would like to see the boards for which you are not happy with the bidding, please use the Report button on the bottom right of the bridge table, it will send us the info we need to look at it and improve it.

As for money, the $20 are there not to make us rich, compared to any other bridge App Shark is practically free, it is there so that only people serious about the game of bridge stay on our system.

Shark is coded by and for bridge enthusiast !!!
