You can play Chicago Bridge against the computer. A game consists of four hands, each independent of the others.
There are no ads and no in-app purchases.
The bidding convention used is SAYC. Since this app cannot handle overcalls, cue bids, and slam conventional bidding, the dealt hands are chosen so that these types of bids do not come up.
Likewise, since the computer defense cannot handle no trump bids, the dealt hands are chosen so that no trump contracts do not come up.
The dealt hands are limited to those which are opened with 1H or 1S. The following types of hands are rejected:
1) final contract is at the one level;
2) final contract is no trumps;
3) responder has a hand that would make a jump bid;
4) misfits;
5) an opponent would open or make an overcall.
