Two challenges, one app

Both sides of the table

🃏

Declarer Challenge

You are South. Make the contract against perfect defenders: safety plays, hold-ups, eliminations, dummy reversals, squeezes and more.

🛡️

Defence Challenge NEW

You sit East or West, with the computer as your partner. Find the lead, the switch, the ruff or the discard that beats a perfect declarer.

How it works

Every hand has a problem only you can solve

Hands come in challenges of three. Get the hand right first time for 10 points, second time for 6, third time for 3, with a bonus for extra tricks. The clock only breaks ties. After every hand a full written explanation walks you through the winning play, trick by trick, and a replay shows it card by card.

🎯

A growing library of real problems

New challenges are added regularly, for declarers and defenders alike.

🏆

Live leaderboards

📱

Works on any device

Phone, tablet or laptop. Install it once and play offline — perfect for a cruise ship.

The Top Ten

Top ten for one challenge:

Challenge a friend

Send your score, see who comes out on top

Once you've finished a challenge, send it to a friend with your score attached — they play the same three hands and find out whether they can beat you. Most points wins; time breaks a tie.

No friend needed. Challenging someone is entirely optional — every hand is yours to play on your own, at your own pace. And once you've finished a hand, the Practise button lets you play it again as often as you like, just for fun, without affecting your score.

Free to start, low cost to continue
