Follow the steps for 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. For a calm first round, focus on one decision. 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.
Practice beyond the first move
A clear plan starts with the current position. All cards need a non-overlapping grouping, at least two sequences and at least one pure sequence. Take the next action only when the current step is clear.

A closer look at one example
Example hand: 5♦ 7♠ 2♥ 3♥ 8♣ A♥ Q♣ 2♦ Q♥ 2♦ 6♣ 5♣ 8♥. Wild rank 10. No full grouping meets the two-sequence and pure-sequence requirement. The penalty for this hand is 63 points. The same rule applies on a phone and on a computer.
Watch out for this
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.
