Declaration Practice: what to know before playing
Take a moment to read the table. Check whether a complete 13-card hand can satisfy every declaration requirement. Return to the explanation when a decision is unclear. Look at the complete hand before deciding. Start a 10-question session. Read the visible rule label and wild rank, if shown. Check the relevant controls before continuing.
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.
Build familiarity through play
Keep the active rule in mind. 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.
The objective of a round
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.
A walkthrough of the rules
- 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.
Getting comfortable with the controls
Tap the answer buttons or selected card; the deadwood exercise uses a numeric input. Next question appears after an answer. Check the relevant controls before continuing. Use the rule sheet as a reference.
One way to understand the rules
Example hand: 10♥ 2♦ 4♦ 4♥ 6♥ 10♣ 5♣ 2♠ 6♦ 7♦ 3♦ 9♣ 5♥. Wild rank 4. No full grouping meets the two-sequence and pure-sequence requirement. The penalty for this hand is 35 points. The same rule applies on a phone and on a computer.
Watch out for this
Before making a move, check the cards in view. Do not judge only the best three cards; every remaining card matters. 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. Use the rule sheet as a reference. 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. A clear plan starts with the current position. 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. Begin with the objective. The same rule applies on a phone and on a computer.

All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Before making a move, check the cards in view. 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. Work at your own pace. 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. For a calm first round, focus on one decision. Return to the explanation when a decision is unclear.
