Find your footing in Declaration Practice
Before making a move, check the cards in view. Check whether a complete 13-card hand can satisfy every declaration requirement. Use another round to revisit a decision. For a calm first round, focus on one decision. Start a 10-question session. Read the visible rule label and wild rank, if shown. Use another round to revisit a decision.
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.
Try a more deliberate round
Work at your own pace. All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. The same rule applies on a phone and on a computer.
What you need to achieve
Check whether a complete 13-card hand can satisfy every declaration requirement. Use another round to revisit a decision. For a calm first round, focus on one decision.
Follow these playing steps
- 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.
How to use the controls
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. Take the next action only when the current step is clear. For a calm first round, focus on one decision.
See how the rules apply
Example hand: Q♠ Q♦ 6♠ Q♥ Q♣ 4♦ 5♣ Joker 5♦ 5♠ 7♠ 6♦ 5♥. Wild rank 11. All thirteen cards can be split into legal non-overlapping melds, including two sequences and a pure sequence. The same rule applies on a phone and on a computer.
A mistake to avoid
For a calm first round, focus on one decision. Do not judge only the best three cards; every remaining card matters. Take the next action only when the current step is clear.
If you are unsure
What is the aim?
Check whether a complete 13-card hand can satisfy every declaration requirement. Take a moment to read the table. Check the relevant controls before continuing.
How do I use the controls?
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. Work at your own pace. Check the relevant controls before continuing.
Which format is available?
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. Keep the active rule in mind. Check the relevant controls before continuing.
What should I check before a move?
Do not judge only the best three cards; every remaining card matters. A clear plan starts with the current position. Take the next action only when the current step is clear.
Can you give an example?
One pure run, another joker-assisted run and two complete sets can cover a valid 13-card hand. Treat this as a chance to practise one rule. The same rule applies on a phone and on a computer.
How many questions are available?
This exercise contains 500 stored questions. A session selects ten without repeating within that session. Look at the complete hand before deciding. The same rule applies on a phone and on a computer.
Can I change a submitted answer?
No. Read the explanation, then continue. Start another session to practise again. Take a moment to read the table. Return to the explanation when a decision is unclear.
Are the answers checked against the rules?
All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Use the rule sheet as a reference. Return to the explanation when a decision is unclear.
Will I always see new cards?
No. The bank is finite, so another session may include a previously played question. For a calm first round, focus on one decision. Check the relevant controls before continuing.
What does the score measure?
The score is the number of correct answers in this ten-question session. It is not a skill certificate or a prediction of match results. Treat this as a chance to practise one rule. Use another round to revisit a decision.
