Making your first moves in Declaration Practice
Keep the active rule in mind. Check whether a complete 13-card hand can satisfy every declaration requirement. Use another round to revisit a decision. Use the rule sheet as a reference. Start a 10-question session. Read the visible rule label and wild rank, if shown. Take the next action only when the current step is clear.
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.
Bring this focus to a round
Take a moment to read the table. All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Check the relevant controls before continuing.
Your objective
Check whether a complete 13-card hand can satisfy every declaration requirement. Check the relevant controls before continuing. Begin with the objective.
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.
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. Use the rule sheet as a reference.
An example before you play
Example hand: A♥ 5♠ 6♦ 2♠ 5♦ 2♥ 2♣ 2♦ A♠ 7♦ Joker 6♠ A♣. Wild rank 12. All thirteen cards can be split into legal non-overlapping melds, including two sequences and a pure sequence. Use another round to revisit a decision.
Check this before moving on
Work at your own pace. Do not judge only the best three cards; every remaining card matters. Return to the explanation when a decision is unclear.
Questions that come up during play
What is the aim?
Check whether a complete 13-card hand can satisfy every declaration requirement. Before making a move, check the cards in view. Use another round to revisit a decision.
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. Take a moment to read the table. Use another round to revisit a decision.
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. A clear plan starts with the current position. Return to the explanation when a decision is unclear.
What should I check before a move?
Do not judge only the best three cards; every remaining card matters. Begin with the objective. Return to the explanation when a decision is unclear.
Can you give an example?
One pure run, another joker-assisted run and two complete sets can cover a valid 13-card hand. Work at your own pace. Take the next action only when the current step is clear.
How many questions are available?
This exercise contains 500 stored questions. A session selects ten without repeating within that session. For a calm first round, focus on one decision. Use another round to revisit a decision.
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. Take the next action only when the current step is clear.
Will I always see new cards?
No. The bank is finite, so another session may include a previously played question. Take a moment to read the table. 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. Look at the complete hand before deciding. Check the relevant controls before continuing.
