Rules, controls and help for Declaration Practice
A clear plan starts with the current position. Check whether a complete 13-card hand can satisfy every declaration requirement. The same rule applies on a phone and on a computer. Use the rule sheet as a reference. Start a 10-question session. Read the visible rule label and wild rank, if shown. Return to the explanation when a decision is unclear.
500 stored and rule-checked questions; ten questions per session. Questions can repeat across sessions. Practice is solo, with no rating, cash reward or account.
Take a closer look while playing
Use the rule sheet as a reference. All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Check the relevant controls before continuing.
Your goal
Check whether a complete 13-card hand can satisfy every declaration requirement. Use another round to revisit a decision. Work at your own pace.
Start here and follow along
- Start a 10-question session. Read the visible rule label and wild rank, if shown.
- All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence.
- Study the complete hand before answering. Choose Valid or Not valid.
- Read the explanation after submitting. Each question accepts one submitted answer.
- Continue to the tenth question for a session score; start another session for a new selection.
Choosing and moving on screen
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. The same rule applies on a phone and on a computer. Before making a move, check the cards in view.
An example before you play
Example hand: 5♠ 5♥ 5♣ 8♥ 4♥ 4♣ 5♦ Joker 4♠ 6♣ 7♥ 5♣ 9♥. Wild rank 12. All thirteen cards can be split into legal non-overlapping melds, including two sequences and a pure sequence. Take the next action only when the current step is clear.
One detail worth checking
Begin with the objective. Do not judge only the best three cards; every remaining card matters. Return to the explanation when a decision is unclear.
