Your guide to Declaration Practice
Begin with the objective. Check whether a complete 13-card hand can satisfy every declaration requirement. Take the next action only when the current step is clear. Take a moment to read the table. 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.
A focus for your next round
Use the rule sheet as a reference. All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Return to the explanation when a decision is unclear.
The goal to keep in mind
Check whether a complete 13-card hand can satisfy every declaration requirement. Take the next action only when the current step is clear. Before making a move, check the cards in view.
Making your moves
- 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.
The controls to know
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. Treat this as a chance to practise one rule.
Follow the example
Example hand: 4♦ 7♣ Q♠ 8♣ Q♥ 8♦ Joker 8♥ 5♦ 9♣ Q♣ 8♣ 8♠. Wild rank 4. 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.
Avoid this misunderstanding
Keep the active rule in mind. Do not judge only the best three cards; every remaining card matters. Use another round to revisit a decision.
Game-specific help
What is the aim?
Check whether a complete 13-card hand can satisfy every declaration requirement. Take a moment to read the table. Return to the explanation when a decision is unclear.
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. For a calm first round, focus on one decision. 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. Look at the complete hand before deciding. Use another round to revisit a decision.
What should I check before a move?
Do not judge only the best three cards; every remaining card matters. Treat this as a chance to practise one rule. Check the relevant controls before continuing.
Can you give an example?
One pure run, another joker-assisted run and two complete sets can cover a valid 13-card hand. Begin with the objective. Return to the explanation when a decision is unclear.
How many questions are available?
This exercise contains 500 stored questions. A session selects ten without repeating within that session. Begin with the objective. Take the next action only when the current step is clear.
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. The same rule applies on a phone and on a computer.
Are the answers checked against the rules?
All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Treat this as a chance to practise one rule. Check the relevant controls before continuing.
Will I always see new cards?
No. The bank is finite, so another session may include a previously played question. Look at the complete hand before deciding. Take the next action only when the current step is clear.
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. Return to the explanation when a decision is unclear.
