Rules, controls and help for Declaration Practice
Work at your own pace. Check whether a complete 13-card hand can satisfy every declaration requirement. Take the next action only when the current step is clear. 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.
An idea for your next attempt
Treat this as a chance to practise one rule. 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.

An example before you play
Example hand: 4♦ 7♠ 8♥ K♥ A♦ Joker 5♠ 6♣ 7♦ 7♦ 4♠ Q♥ 8♣. Wild rank 1. No full grouping meets the two-sequence and pure-sequence requirement. The penalty for this hand is 76 points. Return to the explanation when a decision is unclear.
Watch out for this
Use the rule sheet as a reference. Do not judge only the best three cards; every remaining card matters. Take the next action only when the current step is clear.
Game-specific help

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. Use the rule sheet as a reference. Take the next action only when the current step is clear.
What should I check before a move?

Can you give an example?
One pure run, another joker-assisted run and two complete sets can cover a valid 13-card hand. Look at the complete hand before deciding. Check the relevant controls before continuing.
How many questions are available?
This exercise contains 500 stored questions. A session selects ten without repeating within that session. Take a moment to read the table. 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. Before making a move, check the cards in view. 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. The same rule applies on a phone and on a computer.
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. The same rule applies on a phone and on a computer.
