How the Lead Gym grades a lead
Bots bid a random deal and you lead. The hidden hands are re-dealt to fit the auction and solved double dummy, so every card gets a score: how often it beats the contract (IMPs) or how many tricks it costs (matchpoints).
1 diamond per deal. Beginners read the stars; stronger players check the card-by-card table.
Lead Gym questions
- What does the Lead Gym cost?
- 1 diamond per deal. Every account gets free diamonds each month.
- How is my opening lead scored?
- Your hand stays fixed. The other three hands are re-dealt to fit the bidding and solved double dummy, so the grade reflects the auction, not one lucky deal.
- Which bidding system do the bots use?
- 2/1 Game Force by default. You can change either side's system before dealing.
- How is this different from lead puzzles?
- Puzzles are curated hands graded on 1,000+ simulated deals, with stars and ELO. The Lead Gym is practice on random deals that doesn't touch your record.
