Declaration Practice: rules and examples
Work at your own pace. Check whether a complete 13-card hand can satisfy every declaration requirement. The same rule applies on a phone and on a computer. A clear plan starts with the current position. 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.
Bring this focus to a round
For a calm first round, focus on one decision. 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 challenge in front of you
Check whether a complete 13-card hand can satisfy every declaration requirement. Check the relevant controls before continuing. Keep the active rule in mind.
How to proceed
- 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 interact with the game
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. Keep the active rule in mind.
An example to follow
Example hand: Joker 2♣ 5♣ K♥ 4♠ 10♦ 6♠ A♣ 5♣ J♠ J♠ 4♥ 8♥. Wild rank 5. No full grouping meets the two-sequence and pure-sequence requirement. The penalty for this hand is 74 points. The same rule applies on a phone and on a computer.
A useful caution
Begin with the objective. Do not judge only the best three cards; every remaining card matters. The same rule applies on a phone and on a computer.
